About This Guide

This guide is for personnel who administer Avaya Aura™ Communication Manager, Avaya Aura Communication Manager Branch (formerly known as Avaya Distributed Office), DHCP, HTTP/ HTTPS servers for Avaya 1600 Series IP Deskphones, a Local Area Network (LAN), or a Web server.

The 1600 Series IP Telephones use Internet Protocol (IP) technology with Ethernet line interfaces and support the H.323 protocol only. The 1600 Series IP Telephones provide support for DHCP, HTTP, and HTTPS over IPv4/UDP, which enhance the administration and servicing of the telephones. These telephones use DHCP to obtain dynamic IP Addresses, and HTTPS or HTTP to download new versions of software or customized settings for the telephones.

CAUTION:

CAUTION: Avaya does not support many of the products mentioned in this document. Take

care to ensure that there is adequate technical support available for servers used with any 1600 Series IP Telephone system. If the servers are not functioning correctly, the 1600 Series IP Telephones might not operate correctly.

1600 Series IP Telephones

The 1600 Series IP Telephones currently support the H.323 signaling protocol.

The H.323 standard provides for real time audio, video, and data communications transmission over a packet network. An H.323 telephone protocol stack comprises several protocols:

● H.225 for registration, admission, status (RAS), and call signaling,

● H.245 for control signaling,

● Real Time Transfer Protocol (RTP), and

● Real Time Control Protocol (RTCP)

The parameters under which the 1600 Series IP Telephones need to operate are summarized as follows:

● Telephone and System Administration on the Avaya Media Server, as covered in

Chapter 4:

Avaya Aura Communication Manager Administration.

● IP address management for the telephone, as covered in DHCP and File Servers on

page 43 for dynamic addressing. For static addressing, see the Avaya 1600 Series IP Deskphones Installation and Maintenance Guide.

● Tagging Control and VLAN administration for the telephone, if appropriate, as covered in

Chapter 7:

● Quality of Service (QoS) administration for the telephone, if appropriate. QoS is covered in

QoS

● Interface administration for the telephone, as appropriate. Administer the telephone to

LAN interface using the PHY1 parameter described in Chapter 3:

Administering Telephone Options.

on page 25 and QoS on page 34.

Network Requirements.

Administer the telephone to PC interface using the PHY2 parameter described in “Local Procedures” in the Avaya 1600 Series IP Deskphones Installation and Maintenance

Guide.

● Application-specific telephone administration, if appropriate, as described in Chapter

8: Administering Applications and Options. An example of application-specific data is

specifying the extent to which users can add/edit/delete data for Contacts entries.

● Protocol administration, for example, Simple Network Management Protocol (SNMP) and

Link Layer Discovery Protocol (LLDP).

Parameter Data Precedence

If a given parameter is administered in multiple places, the last server to provide the parameter has precedence. The precedence, from lowest to highest, is:

1. LLDP,

2. Manual administration, with the two exceptions described for the system parameter

STATIC

3. DHCP,

4. HTTP/HTTPS script file,

5. the Avaya Media Server, and finally,

6. Backup files, if administered and if permitted.

Settings the IP telephone receives from backup files or the media server overwrite any previous settings, including manual settings. The only exception to this sequence is in the case of VLAN IDs. In the case of VLAN IDs, LLDP settings of VLAN IDs are the absolute authority. Then the usual sequence applies through HTTP/HTTPS.

on page 72,

Parameter Data Precedence

Note:

Note: For the L2QVLAN and L2Q system values, LLDP settings of VLAN IDs are the

absolute authority only if the LLDP task receives the VLAN IDs before DHCP and HTTP, and the DHCP client of the telephone is activated at all. If the LLDP task receives the VLAN IDs after DHCP negotiation, several criteria must be successful before the telephone accepts VLAN IDs from LLDP. For more information, see Link Layer Discovery Protocol (LLDP)

The Administrative Process

The following list depicts administration for a typical 1600 Series IP Telephone network. Your own configuration might differ depending on the servers and system you have in place.

1. LAN and applicable servers administered to accept the telephones.

2. Telephone software downloaded from the Avaya support site.

3. 46xxsettings file updated with site-specific information, as applicable.

4. 1600 Series Telephones installed. For more information, see the Avaya 1600 Series IP Deskphones Installation and Maintenance Guide.

Telephone Initialization Process

These steps offer a high-level description of the information exchanged when the telephone initializes and registers. This description assumes that all equipment is properly administered ahead of time. This description can help you understand how the 1600 Series IP Telephones relate to the routers and servers in your network.

Step 1: Telephone to Network

The telephone is appropriately installed and powered. After a short initialization process, the telephone identifies the LAN speed and sends a message out into the network, identifying itself and requesting further information. A router on the network receives and relays this message to the appropriate DHCP server if the phone IP address is 0.0.0.0.

Issue 5 April 2010 17

Page 18

Administration Overview and Requirements

Step 2: DHCP Server to Telephone

The DHCP file server provides information to the telephone, as described in DHCP and File

Servers on page 43. Among other data passed to the telephone is the IP address of the HTTP

or HTTPS server.

Step 3: Telephone and File Server

The 1600 Series IP Telephones can download script files and settings files from either an HTTP or HTTPS server. These telephones can also download the application files from the HTTP server. The telephone queries the file server, which transmits a script file to the telephone. This script file, at a minimum, tells the telephone which application file the telephone must use. The application file is the software that has the telephony functionality.

The telephone uses the script file to determine if it has the proper application file. If the telephone determines the proper application file is missing, the telephone requests an application file download from the HTTP server. The telephone then downloads the file and conducts some checks to ensure that the file was downloaded properly. If the telephone determines it already has the proper file, the telephone proceeds as described in the next paragraph without downloading the application file again.

The telephone checks and loads the application file, then uses the script file to look for a settings file, if appropriate. The optional settings file can contain settings you have administered for any or all of the 1600 Series IP Telephones in your network. For more information about this download process and settings file, see Chapter 6:

Step 4: Telephone and the Call Server

The call server referred to in this step is the Avaya Media Server.

In this step, the telephone might prompt the user for an extension and password. The telephone uses that information to exchange a series of messages with the call server. For a new installation and for full service, the user can enter the telephone extension and password. For a restart of an existing installation, this information is already stored on the telephone, but the user might have to confirm the information. The telephone and the call server exchange more messaging. The expected result is that the telephone is appropriately registered and call server data such as feature button assignments are downloaded.

Error Conditions

The 1600 Series IP Telephones support a feature called Unnamed Registration. Unnamed Registration allows a telephone to register with the Avaya Media Server without an extension, assuming the Avaya Media Server also supports this feature. To invoke Unnamed Registration, take no action. Allow the Extension... prompt to display for 60 seconds without making an entry. The telephone automatically attempts to register by means of Unnamed Registration. A telephone registered with Unnamed Registration has the following characteristics:

● only one call appearance,

● no administrable features,

● can make only outgoing calls, subject to call server Class of Restriction/Class of Service

limitations, and

● can be converted to normal “named” registration by the user entering a valid extension and

password (that is, logging in).

Note:

Note: Unnamed Registration requires administration on the Avaya Aura

Communication Manager system.

You can also administer the telephone to avoid unnamed registration and remain unregistered if no extension and password are provided. For more information, see UNNAMEDSTAT

Table 8

For more information about the installation process, see the Avaya 1600 Series IP Deskphones Installation and Maintenance Guide.

Error Conditions

Assuming proper administration, most of the problems reported by telephone users are likely to be LAN-based. Quality of Service, server administration, and other issues can impact user perception of IP telephone performance.

The Avaya 1600 Series IP Deskphones Installation and Maintenance Guide covers possible operational problems that might be encountered after successful 1600 Series IP Telephone installation.

Chapter 3: Network Requirements

Network Assessment

Perform a network assessment to ensure that the network will have the capacity for the expected data and voice traffic, and that it can support for all applications:

● H.323,

● DHCP,

● HTTP/HTTPS, and

● Jitter buffers

Also, QoS support is required to run VoIP on your configuration. For more information, see

Appendix B: Related Documentation

and UDP Port Selection on page 34.

Hardware Requirements

To operate properly, you need:

● Category 5e cables designed to the IEEE 802.3af-2003 standard, for LAN powering,

● For Avaya Aura Communication Manager: TN2602 IP Media Processor circuit pack. Sites

with a TN2302 IP Media Processor circuit pack are strongly encouraged to install a TN2602 circuit pack.

● For Avaya Aura Communication Manager: TN799C or D Control-LAN (CLAN) circuit pack.

Important:

Important: IP telephone firmware Release 1.0 or greater requires TN799C V3 or greater

CLAN circuit pack(s). For more information, see the Avaya Aura Communication Manager Software and Firmware Compatibility Matrix on the Avaya support Web site

Network Requirements

Server Requirements

Two server types can be configured for the 1600 Series IP Telephones:

● DHCP

● HTTP or HTTPS

Note:

Note: HTTPS does not provide all of the functionality of HTTP. For example, backup/

restore is unavailable via HTTPS, and firmware cannot be downloaded via HTTPS.

While the servers listed provide different functions that relate to the 1600 Series IP Telephones, they are not necessarily different boxes. For example, DHCP provides file management whereas HTTP provides application management, yet both functions can co-exist on one hardware unit. Any standards-based server is recommended.

For parameters related to Avaya Media Server information, see Chapter 4:

Communication Manager Administration, and the administration documentation for your call

server. For parameters related to DHCP and file servers, see Chapter 5:

CAUTION:

CAUTION: The telephones obtain important information from the script files on the file server

and depend on the application file for software upgrades. If the DHCP file server is unavailable when the telephones reset, the telephones register with the media server and operate. Some features might not be available. To restore them you need to reset the telephone(s) when the file server is available.

DHCP Server

Avaya recommends that a DHCP server and application be installed and that static addressing be avoided. Install the DHCP server and application as described in DHCP and File Servers page 43.

Required Network Information

Before you administer DHCP and HTTP, and TLS, as applicable, complete the information in

Table 3

Gatekeeper in your configuration, complete Table 3

The 1600 Series IP Telephones support specifying a list of IP addresses for a gateway/router, HTTP/HTTPS server, and Avaya Media Server Gatekeeper(s). Each list can contain up to 255 total ASCII characters, with IP addresses separated by commas with no intervening spaces. Depending on the specific DHCP application, only 127 characters might be supported.

When specifying IP addresses for the file server or media server, use either dotted decimal format (“xxx.xxx.xxx.xxx”) or DNS names. If you use DNS, the system value DOMAIN is appended to the IP addresses you specify. If DOMAIN is null, the DNS names must be fully qualified, in accordance with IETF RFCs 1034 and 1035. For more information about DNS, see

Network Requirements

Other Network Considerations

SNMP

The 1600 Series IP Telephones are fully compatible with SNMPv2c and with Structure of Management Information Version 2 (SMIv2). The telephones respond correctly to queries from entities that comply with earlier versions of SNMP, such as SNMPv1. “Fully compatible” means that the telephones respond to queries directed either at the MIB-II or the read-only Custom MIB. Read-only means that the values therein cannot be changed externally by means of network management tools.

You can use the system value SNMPADD to restrict the IP addresses from which the telephone accepts SNMP queries. You can also customize your community string with the system value SNMPSTRING. For more information, see Chapter 5:

Series IP Telephone Customizable System Parameters.

Note:

Note: As of Release 1.0, SNMP is disabled by default. Administrators must initiate

SNMP by setting the SNMPADD and SNMPSTRING system values appropriately.

Reliability and Performance

Other Network Considerations

QoS

All 1600 Series IP Telephones respond to a ping or traceroute message sent from the DEFINITY

, MultiVantage™, Avaya Aura Communication Manager, or Avaya Aura Communication Manager Branch system (formerly known as Avaya Distributed Office) or any other network source. The telephones do not originate a ping or traceroute. The 1600 Series IP Telephones offer and support “remote ping” and “remote traceroute.” The switch can instruct the telephone to originate a ping or a traceroute to a specified IP address. The telephone carries out that instruction and sends a message to the switch indicating the results. For more information, see your switch administration documentation.

If applicable, the telephones test whether the network Ethernet switch port supports IEEE

802.1P/Q tagged frames by ARPing the router with a tagged frame. For more information, see

VLAN Considerations

on page 73. If your LAN environment includes Virtual LANs (VLANs),

your router must respond to ARPs for VLAN tagging to work properly.

For more information about the extent to which your network can support any or all of the QoS initiatives, see your LAN equipment documentation. See QoS

on page 34 about QoS

implications for the 1600 Series IP Telephones.

All 1600 Series IP Telephones provide some detail about network audio quality. For more information see, Network Audio Quality Display on

1600 Series IP Telephones on page 26.

IEEE 802.1P and 802.1Q

For more information about IEEE 802.1P and IEEE 802.1Q and the 1600 Series IP Telephones, see IEEE 802.1 the 802.1Q tag are reserved for identifying packet priority to allow any one of eight priorities to be assigned to a specific packet.

● 7: Network management traffic

● 6: Voice traffic with less than 10ms latency

● 5: Voice traffic with less than 100ms latency

● 4: “Controlled-load” traffic for critical data applications

● 3: Traffic meriting “extra-effort” by the network for prompt delivery, for example, executive

e-mail

● 2: Reserved for future use

● 0: The default priority for traffic meriting the “best-effort” for prompt delivery of the network.

Note: Priority 0 is a higher priority than Priority 1.

Network Audio Quality Display on 1600 Series IP Telephones

All 1600 Series IP Telephones give the user an opportunity to monitor network audio performance while on a call. For more information, see the telephone user guide.

While on a call, the telephones display network audio quality parameters in real-time, as shown in Ta bl e 4

Table 4: Parameters in Real-Time

Parameter Possible Values

Received Audio Coding G. 711 , G.711u, G.711a, G.72 6, G.729A, or G.729B.

Packet Loss "No data" or a percentage. Late and out-of-sequence packets

are counted as lost if they are discarded. Packets are not counted as lost until a subsequent packet is received and the loss confirmed by the RTP sequence number.

Packetization Delay "No data" or an integer number of milliseconds. The number

reflects the amount of delay in received audio packets, and includes any potential delay associated with the codec.

One-way Network Delay "No data" or an integer number of milliseconds. The number is

one-half the value RTCP computes for the round-trip delay.

Network Jitter Compensation Delay

"No data" or an integer number of milliseconds reporting the average delay introduced by the jitter buffer of the telephone.

The implication for LAN administration depends on the values the user reports and the specific nature of your LAN, like topology, loading, and QoS administration. This information gives the user an idea of how network conditions affect the audio quality of the current call. Avaya assumes you have more detailed tools available for LAN troubleshooting.

IP Address Lists and Station Number Portability

The 1600 Series IP Telephones provide the capability to specify IP address lists. On startup or a reboot, the telephone attempts to establish communication with these various network elements in turn. The telephone starts with the first address on the respective list. If the communication is denied or times out, the telephone proceeds to the next address on the appropriate list and tries that one. The telephone does not report failure unless all the addresses on a given list fail, thereby improving the reliability of IP telephony.

26 Avaya 1600 Series IP Deskphones Administrator Guide

Page 27

Other Network Considerations

This capability also has the advantage of making station number portability easier. Assume a situation where the company has multiple locations in London and New York, all sharing a corporate IP network. Users want to take their telephones from their offices in London and bring them to New York. When users start up their telephones in the new location, the local DHCP server usually routes them to the local call server. With proper administration of the local DHCP server, the telephone knows to try a second call server IP address, this one in London. The user can then be automatically registered with the London call server.

Chapter 5:

Server Administration contains details on administration of DHCP servers for lists of

alternate media servers, router/gateways, and HTTP/HTTPS servers. For more information, see DNS Addressing

on page 76.

TCP/UDP Port Utilization

The 1600 Series IP Telephones use a variety of protocols, particularly TCP and UDP, to communicate with other equipment in the network. Part of this communication identifies which TCP or UDP ports each piece of equipment uses to support each protocol and each task within the protocol. For additional TCP/UDP port utilization information as it applies to Avaya Aura Communication Manager, see UDP Port Selection

Depending on your network, you might need to know what ports or ranges are used in the operation of 1600 Series IP Telephones. Knowing these ports or ranges helps you administer your networking infrastructure.

uses the IP Interfaces screen. For more information, see Administration for Network Connectivity for Avaya Aura™ Communication Manager (Document 555-233-504).

● On the Customer Options form, verify that the IP Stations field is set to “y” (Yes). If it is

not, contact your Avaya sales representative. The IP Softphone field does not have to be set to “y” (Yes).

UDP Port Selection

The 1600 Series IP Telephones can be administered from the Avaya Aura Communication Manager Network Region form to support UDP port selection. Locate specific port assignment diagrams in the 1600 IP Telephone Installation and Maintenance Guide. For information about Avaya Aura Communication Manager implementation, see Administration for Network Connectivity for Avaya Aura™ Communication Manager (Document Number 555-233-504) on the Avaya support Web site.

Administer the switch to use a port within the proper range for the specific LAN, and the IP telephone(s) copy that port. If no UDP port range is administered on the switch, the IP telephone uses an even-numbered port, randomly selected from the interval 4000 to 10000.

RSVP and RTCP

Avaya IP Telephones implement the Resource ReSerVation Protocol (RSVP) administered from the media server and the RTP Control Protocol (RTCP). The Avaya Voice over IP (VoIP) Monitoring Manager (VMON) software can then provide real-time monitoring and historical data of audio quality for VoIP calls.

The only way to change these parameters is by appropriate switch administration. For more information, see your Avaya Media Server administration documentation and Administration for Network Connectivity for Avaya Aura™ Communication Manager (Document Number 555-233-504).

QoS

The 1600 Series IP Telephones support both IEEE 802.1P/Q and DiffServ. Other network-based QoS initiatives such as UDP port selection do not require support by the telephones. However, they contribute to improved QoS for the entire network.

IEEE 802.1P and 802.1Q

The 1600 Series IP Telephones can simultaneously support receipt of packets using, or not using, 802.1Q parameters. To support IEEE 802.1P/Q, you can administer 1600 Series IP Telephones from the network by appropriate administration of the DHCP or HTTP/HTTPS servers, or by using dialpad input at the telephone.

NAT

Media Server (Switch) Administration

Important:

Important: Avaya Aura Communication Manager administration always takes precedence

over manual administration of IEEE 802.1P/Q data.

The four IEEE 802.IP/Q QoS parameters in the telephones that can be administered on the IP Network Region form are L2Q, L2QVLAN, L2QAUD, and L2QSIG. To set these parameters at the switch, see “About Quality of Service (QoS) and voice quality administration” in Administration for Network Connectivity for Avaya Aura™ Communication Manager (Document Number 555-233-504). To set these parameters manually see the 1600 IP Telephone Installation and Maintenance Guide. You can specify VLAN ID and VLANTEST values with the ADDR Local Administrative Option.

Note:

Note: All local administrative procedures are on a phone-by-phone basis.

Administration using Avaya Aura Communication Manager, DHCP, and HTTP applies to the telephone system itself or to a range of telephones.

Network Address Translation (NAT) usage can lead to problems that affect the consistency of addressing throughout your network. All H.323 IP Telephones support NAT interworking. Support for NAT does not imply support for Network Address Port Translation (NAPT). The telephones do not support communication to the PBX through any NAPT device.

NAT requires specific administration on the media server. A direct Avaya IP Telephone-to-Avaya IP Telephone call with NAT requires Avaya Aura Communication Manager Release 3.0 or greater software. For more information, see Administration for Network Connectivity for Avaya Aura™ Communication Manager (Document Number 555-233-504) on the Avaya support Web site.

DIFFSERV

The DiffServ values change to the values administered on the media server as soon as the telephone registers. For more information, see Chapter 4 “Network Quality Administration” in Administration for Network Connectivity for Avaya Aura™ Communication Manager (Document Number 555-233-504). Unless there is a specific need in your enterprise LAN, Avaya recommends that you do not change the default values.

Voice Mail Integration

1600 Series IP Telephones with Avaya Aura Communication Manager 5.2 Native Support

Release 1.1 provides native support for 1600 Series IP Telephones running on Avaya Aura Communication Manager Release 5.2 or later. When native support applies, pressing the Messages button causes the telephone to first determine if the call server has a dedicated number for retrieving voice mail and when found, to proceed with voice mail retrieval.

1600 Series IP Telephones Aliased as 4600 Series IP Telephones

When native support does not apply, 1600 Series IP Telephones are aliased as 4600 Series IP Telephones and run under an Avaya Aura Communication Manager Release earlier than 5.2. In this case, use the settings file to configure the Messages button by setting the system parameter MSGNUM

to any dialable string. MSGNUM examples are:

● a standard telephone number the telephone should dial to access your voice mail system,

such as AUDIX or Octel.

● a Feature Access Code (FAC) that allows users to transfer an active call directly to voice

mail. FACs are supported only for QSIG-integrated voice mail systems like AUDIX or Octel. QSIG is an enhanced signaling system that allows the voice mail system and Avaya Aura Communication Manager Automated Call Processing (ACP) to exchange information.

When the user presses the Messages button on the telephone, that number or FAC is automatically dialed, giving the user one-touch access to voice mail.

The settings file specifies the telephone number to be dialed automatically when the user presses this button. The command is:

SET MSGNUM 1234

where 1234 is the Voice Mail extension (Avaya Aura Communication Manager hunt group or VDN). For more information, see Table 8

MSGNUM is used both in native support and when the telephone is aliased using non-native support. Messaging must be configured for native support.

A separate Voice Mail extension can be administered for each station.

Release 1.1 supports the functionality introduced on Avaya Aura Communication Manager Release 5.2 that allows call server administration of the GROUP parameter on a station-by-station basis. As covered in The GROUP System Value Identifier can be used in conjunction with the 46xxsettings file to allow administration to apply to specific “groups” of telephones. Before Release 1.1, the Group Identifier had to be administered locally on each applicable telephone. As of Release 1.1, the Group Identifier can be administered centrally, and downloaded to each applicable telephone. The GROUP ID parameter is administered on page 3 of the Change Station Form. Once downloaded, the Group Identifier takes effect starting with the next telephone boot-up.

Chapter 5: Server Administration

Software Checklist

Ensure that you own licenses to use the DHCP, HTTP, and HTTPS server software.

Note:

Note: You can install the DHCP and HTTP server software on the same machine.

CAUTION:

CAUTION: The firmware in the 1600 Series IP Telephones reserves IP addresses of the form

192.168.0.24 and 192.168.1.x for internal communications. The telephone(s) improperly use addresses you specify if they are of that form.

DHCP and File Servers

Dynamic Host Configuration Protocol (DHCP) minimizes maintenance for a 1600 Series IP Telephone network by removing the need to individually assign and maintain IP addresses and other parameters for each IP telephone on the network.

The DHCP server provides the following information to the 1600 Series IP Telephones:

● IP address of the 1600 Series IP Telephone(s)

● IP address of the Gatekeeper board on the Avaya Media Server

● IP address of the HTTP or HTTPS server

● The subnet mask

● IP address of the router

● DNS Server IP address

Administer the LAN so each IP telephone can access a DHCP server that contains the IP addresses and subnet mask.

The IP telephone cannot function without an IP address. The failure of a DHCP server at boot time leaves all the affected telephones unusable. A user can manually assign an IP address to an IP telephone. When the DHCP server finally returns, the telephone never looks for a DHCP server unless the static IP data is unassigned manually. In addition, manual entry of IP data is an error-prone process.

Issue 5 April 2010 43

Page 44

Server Administration

Avaya recommends that:

● A minimum of two DHCP servers be available for reliability.

● A DHCP server be available when the IP telephone reboots.

● A DHCP server be available at remote sites if WAN failures isolate IP telephones from the

central site DHCP server(s).

The file server provides the 1600 Series IP Telephone with a script file and, if appropriate, new or updated application software. See Step 3: Telephone and File Server

Telephone Initialization Process

. In addition, you can edit an associated settings file to customize telephone parameters for your specific environment. For more information, see

CAUTION:

CAUTION: Before you start, understand your current network configuration. An improper

installation can cause network failures or reduce the reliability and performance of your network.

DHCP Generic Setup

This document is limited to describing a generic administration that works with the 1600 Series IP Telephones. Three DHCP software alternatives are common to Windows operating systems:

● Windows NT

● Windows 2000

● Windows 2003

4.0 DHCP Server

DHCP Server

44 Avaya 1600 Series IP Deskphones Administrator Guide

Page 45

DHCP Server Administration

Any other DHCP application might work. It is the responsibility of the customer to install and configure the DHCP server correctly.

DHCP server setup involves:

1. Installing the DHCP server software according to vendor instructions.

2. Configuring the DHCP server with:

● IP addresses available for the 1600 Series IP Telephones.

● The following DHCP options:

- Option 1 - Subnet mask.

As described in Table 3

, item 3.

- Option 3 - Gateway (router) IP address(es).

As described in Table 3

, item 1. If using more than one address, the total list can contain up to 255 total ASCII characters. You must separate IP addresses with commas with no intervening spaces.

- Option 6 - DNS server(s) address list.

If using more than one address, the total list can contain up to 127 total ASCII characters. You must separate IP addresses with commas with no intervening spaces. At least one address in Option 6 must be a valid, non zero, dotted decimal address.

- Option 12 - Host Name.

Value is AVohhhhhh, where: o is “A” if the OID (first three octets) of the MAC address for the telephone is 00-04-0D. “E” if the OID is 00-09-6E, “L” if the OID is 00-60-1D, and “X” if the OID is anything else and where hhhhhh are ASCII characters for the hexadecimal representation of the last three octets of the MAC address for the telephone.

- Option 15 - DNS Domain Name.

This string contains the domain name to be used when DNS names in system parameters are resolved into IP addresses. This domain name is appended to the DNS name before the 1600 IP Telephone attempts to resolve the DNS address. Option 15 is necessary if you want to use a DNS name for the HTTP server. Otherwise, you can specify a DOMAIN as part of customizing HTTP as indicated in

DNS Addressing

on page 76.

- Option 51 - DHCP lease time.

If this option is not received, the DHCPOFFER is not be accepted. Avaya recommends a lease time of six weeks or greater. If this option has a value of FFFFFFFF hex, the IP address lease is assumed to be infinite as per RFC 2131, Section 3.3, so that renewal and rebinding procedures are not necessary even if Options 58 and 59 are received. Expired leases cause Avaya IP Telephones to reboot. Avaya recommends providing enough leases so an IP address for an IP telephone does not change if it is briefly taken offline.

Issue 5 April 2010 45

Page 46

Server Administration

Note:

Note: The DHCP standard states that when a DHCP lease expires, the device should

immediately cease using its assigned IP address. If the network has problems and the only DHCP server is centralized, the server is not accessible to the given telephone. In this case the telephone is not usable until the server can be reached. Avaya recommends, once assigned an IP address, the telephone continues using that address after the DHCP lease expires, until a conflict with another device is detected. As Ta bl e 8:

Parameters indicates, the system parameter DHCPSTD allows an administrator

to specify that the telephone will either: a). Comply with the DHCP standard by setting DHCPSTD to “1”, or b). Continue to use its IP address after the DHCP lease expires by setting DHCPSTD to “0.”

The latter case is the default. If the default is invoked, after the DHCP lease expires the telephone sends an ARP Request for its own IP address every five seconds. The request continues either forever, or until the telephone receives an ARP Reply. After receiving an ARP Reply, the telephone displays an error message, sets its IP address to 0.0.0.0, and attempts to contact the DHCP server again.

1600 Series IP Telephone Customizable System

- Option 52 - Overload Option, if desired. If this option is received in a message, the telephone interprets the sname and file fields in accordance with IETF RFC 2132, Section 9.3, listed in Appendix B: Related Documentation

- Option 53 - DHCP message type. Value is 1 (DHCPDISCOVER) or 3 (DHCPREQUEST).

- Option 55 - Parameter Request List. Acceptable values are:

1 (subnet mask), 3 (router IP address[es]) 6 (domain name server IP address[es]) 15 (domain name) NVSSON (site-specific option number)

- Option 57 - Maximum DHCP message size.

- Option 58 - DHCP lease renew time. If not received or if this value is greater than that for Option 51, the default value of T1 (renewal timer) is used as per IETF RFC 2131, Section 4.5, listed in Related

Documentation.

- Option 59 - DHCP lease rebind time. If not received or if this value is greater than that for Option 51, the default value of T2 (rebinding timer) is used as per RFC 2131, Section 4.5

DHCP Server Administration

The 1600 Series IP Telephones do not support Regular Expression Matching, and therefore, do not use wildcards. For more information, see Administering Options for the

1600 Series IP

Telephones on page 67.

In configurations where the upgrade script and application files are in the default directory on the HTTP server, do not use the HTTPDIR=<path>.

You do not have to use Option 242. If you do not use this option, you must ensure that the key information, especially HTTPSRVR and MCIPADD, is administered appropriately elsewhere.

Avaya recommends that you administer DHCP servers to deliver only the options specified in this document. Administering additional, unexpected options might have unexpected results, including causing the IP telephone to ignore the DHCP server.

The media server name and HTTP server name must each be no more than 32 characters in length.

Examples of good DNS administration include:

- Option 6: “aaa.aaa.aaa.aaa”

- Option 15: “dnsexample.yourco.com,zzz.zzz.zzz.zzz”

- Option 242: “MCIPADD=xxxx.xxx.xxx.xxx”

Depending on the DHCP application you choose, be aware that the application most likely does not immediately recycle expired DHCP leases. An expired lease might remain reserved for the original client a day or more. For example, Windows NT

DHCP reserves expired leases for about one day. This reservation period protects a lease for a short time. If the client and the DHCP server are in two different time zones, the clocks of the computers are not in sync, or the client is not on the network when the lease expires, there is time to correct the situation.

The following example shows the implication of having a reservation period: Assume two IP addresses, therefore two possible DHCP leases. Assume three IP telephones, two of which are using the two available IP addresses. When the lease for the first two telephones expires, the third telephone cannot get a lease until the reservation period expires. Even if the other two telephones are removed from the network, the third telephone remains without a lease until the reservation period expires.

HTTP Generic Setup

You can store the same application software, script file, and settings file on an HTTP server as you can on a TFTP server. TFTP is not supported for 1600 Series IP Telephones. With proper administration, the telephone seeks out and uses that material. Some functionality might be lost by a reset if the HTTP server is unavailable. For more information, see DHCP and File

Servers on page 43.

HTTP Generic Setup

CAUTION:

CAUTION: The files defined by HTTP server configuration must be accessible from all IP

telephones invoking those files. Ensure that the file names match the names in the upgrade script, including case, since UNIX systems are case-sensitive.

Note:

Note: Use any HTTP application you want. Commonly used HTTP applications include

Apache

Important:

Important: You must use the Avaya Web configuration server to obtain HTTPS so

and Microsoft® IIS™.

information is authenticated.

The Avaya Web configuration server does not support backup/restore. If you intend to use HTTP for backup/restore purposes, you must use an HTTP server that is independent of the Avaya Web configuration server.

To set up an HTTP server:

● Install the HTTP server application.

● Administer the system parameter HTTPSRVR to the address(es) of the HTTP server.

Include these parameters in DHCP Option 242, or the appropriate SSON Option.

● Download the upgrade script file and application file(s) from the Avaya Web site

http://www.avaya.com/support Contents of the Settings File

to the HTTP server. For more information, see

on page 64.

Note:

Note: Many LINUX servers distinguish between upper and lower case names. Ensure

that you specify the settings file name accurately, as well as the names and values of the data within the file.

If you choose to enhance the security of your HTTP environment by using Transport Layer Security (TLS), you also need to:

● Install the TLS server application.

● Administer the system parameter TLSSRVR to the address(es) of the Avaya HTTPS

server.

HTTP Configuration for Backup/Restore

For IIS Web Servers

For IIS 4.0 (WinNT4.0), IIS 5.0 (Win2000), IIS 5.1 (WinXP), IIS 6.0 (Win2003):

1. Create a “backup” folder under the root directory of your Web server. All backup files will be stored in that directory.

For example, if your backup folder is C:/Inetpub/wwwroot/backup the 46xxsettings.txt file should have a line similar to:

[SET BRURI http://www.website.com/backup/

If your backup folder is the root directory, the 46xxsettings.txt file should have a line similar to:

[SET BRURI http://www.website.com/

2. Use Internet Information Services Manager or Internet Information Services depending on your OS. Go to Start --> Settings --> Control Panel --> Administrative Tools.

3. Right click on the folder created for backup, or right click on Default Web Site if there is no specific backup directory.

4. Select Properties.

5. In the Directory tab, make sure the Write box is checked.

]

56 Avaya 1600 Series IP Deskphones Administrator Guide

Page 57

HTTP Configuration for Backup/Restore

Additional step for IIS 6.0 (Win2003):

1. Use Internet Information Services. Go to Start --> Settings --> Control Panel --> Administrative Tools.

2. Below Default Web Site select Web Services Extension.

3. Make sure the WebDAV option is set to Allowed.

For Apache Web servers:

1. Create a “backup” folder under the root directory of your Web server, and make the folder writable by everyone. All backup files will be stored in that directory.

If your backup folder is for instance C:/Program Files/Apache Group/Apache2/htdocs/ backup, the 46xxsettings.txt file should have a line similar to:

[SET BRURI http://www.website.com/backup/

]

If your backup folder is the root directory, the 46xxsettings.txt file should have a line similar to:

[SET BRURI http://www.website.com/

]

2. Edit your Web server configuration file httpd.conf.

3. Uncomment the two LoadModule lines associated with DAV:

LoadModule dav_module modules/mod_dav.so

LoadModule dav_fs_module modules/mod_dav_fs.so

Note:

Note: If these modules are not available on your system, typically the case on some

Unix/Linux Apache servers, you have to recompile these two modules (mod_dav & mod_dav_fs) into the server. Other ways to load these modules might be available. Check your Apache documentation at http://httpd.apache.org/docs/ more details.

4. Add the following lines in the httpd.conf file:

# WebDAV configuration

DavLockDB "C:/Program Files/Apache Group/Apache2/var/DAVLock"

for

Dav On

</Location>

For Unix/Linux Web servers the fourth line might look more like:

DavLockDB/usr/local/apache2/var/DAVLock

5. Create the var directory and make it writable by everyone. Right click Properties-->Security-->Add-->Everyone-->Full Control.

Chapter 6: Telephone Software and Application

Files

General Download Process

The 1600 Series IP Telephones download script files and settings files from either an HTTP or HTTPS server. These telephones download the application files from the HTTP server. The HTTPS server applies only if the server supports Transport Layer Security (TLS) encryption.

Note:

Note: The script files, application files, and settings files discussed in this chapter are

identical for HTTP and HTTPS servers. The generic term “file server” refers to both “HTTP server” and “HTTPS server.”

The file downloading process is the same for both servers, except when you use an HTTPS server, a TLS server is contacted first. The telephone queries the file server, which transmits a script file to the telephone. The script file tells the telephone which application file the telephone must use. The application file is the software that has the telephony functionality, and is easily updated for future enhancements. In a newly installed telephone, the application file might be missing. In a previously installed telephone, the application file might not be the proper one. In both cases, the telephone requests a download of the proper application file from the HTTP server. The file server downloads the file and conducts some checks to ensure that the file was downloaded properly. If the telephone determines it already has the proper file, the telephone proceeds to the next step without downloading the application file again.

After checking and loading the application file, the 1600 Series IP Telephone, if appropriate, uses the script file to look for a settings file. The settings file contains options you have administered for any or all of the 1600 Series IP Telephones in your network. For more information about the settings file, see Contents of the Settings File

Software

When shipped from the factory, the1600 Series IP Telephones might not contain sufficient software for registration and operation. When the telephone is first plugged in, a software download from an HTTP server starts to give the phone its proper functionality.

For software upgrade downloads, the call server provides the capability for a remote restart of the 1600 Series IP Telephone. As a result of restarting, the telephone automatically starts reboot procedures. If new software is available on the server, the telephone downloads it as part of the reboot process. The Avaya 1600 Series IP Deskphones Installation and Maintenance Guide covers upgrades to a previously installed telephone and related information.

1600 Series IP Telephone Scripts and Application Files

Choosing the Right Application File and Upgrade Script File

The software releases containing the files needed to operate the 1600 Series IP Telephones are bundled together. You download this self-extracting executable file to your file server from the Avaya support Web site at: http://www.avaya.com/support and unzipped format.

The bundle contains:

● An upgrade script file and a settings file, which allow you to upgrade to new software

releases and new functionality without having to replace IP telephones.

● Application files for all current 1600 Series IP Telephones.

● Other useful information such as a ReadMe file and a settings file template to customize

parameters and settings, and the latest binary code.

. The file is available in both zipped

● Font files

● Language files

Upgrade Script File

An upgrade script file tells the IP telephone whether the telephone needs to upgrade software. The Avaya IP Telephones attempt to read this file whenever they reset. The upgrade script file also points to the settings file.

You download a default upgrade script file, sometimes called the “script file,” from

http://www.avaya.com/support

customer-definable options. This file must reside in the same directory as the upgrade script file, and must be called 46xxsettings.txt. The settings file contains settings for 1600, 9600, and 4600 Series IP Telephones.

Note:

Note: Avaya recommends that the settings file have the extension *.txt. The Avaya IP

Telephones can operate without this file. You can also change these settings with DHCP or, in some cases, from the dialpad of the telephone.

. This file allows the telephone to use default settings for

62 Avaya 1600 Series IP Deskphones Administrator Guide

Page 63

Settings File

The settings file contains the option settings you need to customize the Avaya IP Telephones for your enterprise.

Note:

Note: You can use one settings file for all your Avaya IP Telephones. The settings file

includes the 1600 Series IP Telephones covered in this document as well as 9600 Series IP Telephones and 4600 Series IP Telephones.

The settings file can include any of five types of statements, one per line:

● Comments, which are statements with a “#” character in the first column.

● Tags, which are comments that have exactly one space character after the initial #,

followed by a text string with no spaces.

● Goto commands, of the form GOTO tag. Goto commands cause the telephone to

continue interpreting the configuration file at the next line after a # tag statement. If no such statement exists, the rest of the configuration file is ignored.

● Conditionals, of the form IF $name SEQ string GOTO tag. Conditionals cause the Goto

command to be processed if the value of name is a case-insensitive equivalent to string. If no such name exists, the entire conditional is ignored. The only system values that can be used in a conditional statement are: BOOTNAME, GROUP, and SIG.

● SET commands, of the form SET parameter_name value. Invalid values cause the

specified value to be ignored for the associated parameter_name so the default or previously administered value is retained. All values must be text strings, even if the value itself is numeric, a dotted decimal IP address, and so on.

1600 Series IP Telephone Scripts and Application Files

Note:

Note: Enclose all data in quotation marks for proper interpretation.

The upgrade script file Avaya provides includes a line that tell the telephone to GET 46xxsettings.txt. This lines causes the telephone to use HTTP or HTTPS to attempt to download the file specified in the GET command. If the file is obtained, its contents are interpreted as an additional script file. That is how your settings are changed from the default settings. If the file cannot be obtained, the telephone continues processing the upgrade script file.

If the configuration file is successfully obtained but does not include any setting changes the telephone stops using HTTP. This happens when you initially download the script file template from the Avaya support Web site, before you make any changes. When the configuration file contains no setting changes, the telephone does not go back to the upgrade script file.

Avaya recommends that you do not alter the upgrade script file. If Avaya changes the upgrade script file in the future, any changes you have made will be lost. Avaya recommends that you use the 46xxsettings file to customize your settings instead. However, you can change the settings file name, if desired, as long as you also edit the corresponding GET command in the upgrade script file.

For more information on customizing your settings file, see Contents of the Settings File

Issue 5 April 2010 63

Page 64

Telephone Software and Application Files

Contents of the Settings File

After checking the application software, the 1600 Series IP Telephone looks for a 46xxsettings file. This optional file is where you identify non-default option settings, application-specific parameters, and so on. You can download a template for this file from the Avaya support Web site. An example of what the file might look like follows.

Note:

Note: The following is intended only as a simple example. Your settings will vary from

the settings shown. This sample assumes specification of a DNS Server and turning off enhanced local dialing for 96xx Series IP Telephones.

DNSSRVR=”dnsexample.yourco.com”

ENDIALSTAT=0

See Chapter 7:

Administering Telephone Options for details about specific values. You

need only specify settings that vary from defaults, although specifying defaults is harmless.

VLAN separation controls whether or not traffic received on the secondary Ethernet interface are forwarded on the voice VLAN and whether network traffic received on the data VLAN are forwarded to the telephone. Add commands to the 46xxsettings.txt file to enable VLAN separation. The following example assumes the voice VLAN ID is “xxx”, the data VLAN ID is “yyy” and the data traffic priority is “z”:

SET VLANSEP 1 SET L2Q 1 (or 0 for auto) SET L2QVLAN xxx SET PHY2VLAN yyy SET PHY2PRIO z

Note:

Note: Also configure the network switch so that 802.1Q tags are not removed from

frames forwarded to the telephone.

The GROUP System Value

You might have different communities of users, all of which have the same telephone model, but which require different administered settings. For example, you might want to restrict Call Center agents from being able to Logoff, which might be an essential capability for “hot-desking” associates. We provide examples of the group settings for each of these situations later in this section.

Use the GROUP system value for this purpose:

1. identify which telephones are associated with which group, and designate a number for each group. The number can be any integer from 0 to 999, with 0 as the default, meaning your largest group is assigned as Group 0.

2. At each non-default telephone, instruct the installer or user to invoke the GROUP Local (dialpad) Administrative procedure as specified in the Avaya 1600 Series IP Deskphones Installation and Maintenance Guide and specify which GROUP number to use. The GROUP System value can only be set on a phone-by-phone basis.

3. Once the GROUP assignments are in place, edit the configuration file to allow each telephone of the appropriate group to download its proper settings.

The GROUP System Value

Here is an example of the configuration file for the Call Center agent:

IF $GROUP SEQ 1 goto CALLCENTER IF $GROUP SEQ 2 goto HOTDESK

{specify settings unique to Group 0}

goto END

# CALLCENTER

{specify settings unique to Group 1}

goto END

# HOTDESK

{specify settings unique to Group 2}

# END

{specify settings common to all Groups}

lists:

Avaya recommends that you administer options on the 1600 Series IP Telephones using script files. Some DHCP applications have limits on the amount of user-specified information. The administration required can exceed those limits for the more full-featured telephone models.

You might choose to completely disable the capability to enter or change option settings from the dialpad. You can set the system value, PROCPSWD, as part of standard DHCP/HTTP administration. Alternately, you can set PROCPSWD on the system-parameters ip-options form, as of Avaya Aura Communication Manager Release 5.2. If PROCPSWD is non-null and consists of 1 to 7 digits, the user cannot invoke any “dialpad options” without first pressing Mute and entering the PROCPSWD value. For more information on dialpad options, see the Avaya 1600 Series IP Deskphones Installation and Maintenance Guide.

CAUTION:

CAUTION: PROCPSWD is likely stored on the server “in the clear” and is sent to the

telephone in the clear. Therefore, do not consider PROCPSWD as a high-security technique to inhibit a sophisticated user from obtaining access to local procedures.

Administering this password can limit access to all local procedures, including V I E W. VIEW is a read-only option that allows review of the current telephone settings.

VLAN Considerations

If your LAN environment does not include Virtual LANs (VLANs), ignore this section. Otherwise, this section contains information on how to administer 1600 Series IP Telephones to minimize registration time and maximize performance in a VLAN environment.

VLAN Tagging

IEEE 802.1Q tagging (VLAN) is a useful method of managing VoIP traffic in your LAN. Avaya recommends that you establish a voice LAN, set L2QVLAN to that VLAN, and provide voice traffic with priority over other traffic. If LLDP was used to set the telephones’ VLAN, that setting

Administering Applications and Options.

Issue 5 April 2010 73

Page 74

Administering Telephone Options

has absolute authority. Otherwise, you can set VLAN tagging manually, by DHCP, or in the 46xxsettings.txt file.

If VLAN tagging is enabled (L2Q=0 or 1), the 1600 Series IP Telephones set the VLAN ID to L2QVLAN, and VLAN priority for packets from the telephone to L2QAUD for audio packets and L2QSIG for signalling packets. The default value (6) for these parameters is the recommended value for voice traffic in IEEE 802.1D.

Regardless of the tagging setting, a 1600 Series IP Telephone will always transmit packets from the telephone at absolute priority over packets from secondary Ethernet. The priority settings are useful only if the downstream equipment is administered to give the voice LAN priority.

VLAN Default Value and Priority Tagging

The system value L2QVLAN is initially set to “0” and identifies the 802.1Q VLAN Identifier. This default value indicates “priority tagging” as defined in IEEE 802.IQ Section 9.3.2.3. Priority tagging specifies that your network closet Ethernet switch automatically insert the switch port default VLAN without changing the user priority of the frame (cf. IEEE 802.1P and 802.1Q).

If you do not want the default VLAN to be used for voice traffic:

● Ensure that the switch configuration lets frames tagged by the 1600 Series IP Telephone

through without overwriting or removing them.

● Set the system value L2QVLAN to the VLAN ID appropriate for your voice LAN.

Another system value you can administer is VLANTEST. VLANTEST defines the number of seconds the 1600 IP Series Telephone waits for a DHCPOFFER message when using a non-zero VLAN ID. The VLANTEST default is “60” seconds. Using VLANTEST ensures that the telephone returns to the default VLAN if an invalid VLAN ID is administered or if the phone moves to a port where the L2QVLAN value is invalid. The default value is long, allowing for the scenario that a major power interruption is causing the phones to restart. Always allow time for network routers, the DHCP servers, etc. to be returned to service. If the telephone restarts for any reason and the VLANTEST time limit expires, the telephone assumes the administered VLAN ID is invalid. The telephone then initiates registration with the default VLAN ID.

Setting VLANTEST to “0” has the special meaning of telling the phone to use a non-zero VLAN indefinitely to attempt DHCP. In other words, the telephone does not return to the default VLAN.

Note:

Note: If the telephone returns to the default VLAN but must be put back on the

L2QVLAN VLAN ID, you must Reset the telephone. See the Reset procedure in the Avaya 1600 Series IP Deskphones Installation and Maintenance Guide.

VLAN Separation

VLAN separation controls whether or not traffic received on the secondary Ethernet interface can be forwarded on the voice VLAN. VLAN separation also controls whether network traffic received on the data VLAN can be forwarded to the telephone. The following system parameters control VLAN separation:

● VLANSEP - enables (1) or disables (0) VLAN separation. The default is 1 (on), which

allows full separation. When set to 0 (off), VLAN IDs are not used as a criteria for forwarding frames.

● L2Q - 802.1Q tagging must be set to 1 (on) or 0 (auto).

● L2QVLAN - must be set to the non-zero VLAN ID of the voice VLAN.

● PHY2VLAN - must be set to the non-zero VLAN ID of the data VLAN, which cannot be the

same as the voice VLAN ID.

● PHY2PRIO - the layer 2 priority value to be used for tagged frames received on the

secondary Ethernet interface.

VLAN Considerations

provides several VLAN separation guidelines.

If Then

or removed and the VLAN ID and tagged frames priority are not changed. The Ethernet switch forwarding logic determines that frames received on the Ethernet line interface are forwarded to the secondary Ethernet interface or to the telephone without regard to specific VLAN IDs or the existence of tags.

VLANSEP is “1” (On/Enabled) All tagged frames received on the secondary

Ethernet interface are changed before forwarding to make the VLAN ID equal to the PHY2VLAN value and the priority value equal to the PHY2PRIO value.

Untagged frames received on the secondary Ethernet interface are not changed before forwarding.

AND the telephone is not tagging frames,

OR if the telephone is tagging frames with a VLAN ID equal to PHY2VLAN,

OR if the PHY2VLAN value is zero.

AND the telephone is tagging frames with a VLAN ID not equal to PHY2VLAN,

AND the PHY2VLAN value is not zero.

The Ethernet switch forwarding logic determines that frames received on the Ethernet line interface are forwarded to the secondary Ethernet interface or to the telephone without regard to specific VLAN IDs or the existence of tags.

Tagged frames received on the Ethernet line interface will only be forwarded to the secondary Ethernet interface if the VLAN ID equals PHY2VLAN.

Tagged frames received on the Ethernet line interface will only be forwarded to the telephone if the VLAN ID equals the VLAN ID used by the telephone.

Untagged frames will continue to be forwarded or not forwarded as determined by the Ethernet switch forwarding logic.

DNS Addressing

The 1600 IP Telephones support DNS addresses and dotted decimal addresses. The telephone attempts to resolve a non-ASCII-encoded dotted decimal IP address by checking the contents of DHCP Option 6. See DHCP Generic Setup in Option 6 must be a valid, non-zero, dotted decimal address, otherwise, DNS fails. The text string for the DOMAIN system parameter (Option 15, Table 8 Option 6 before the telephone attempts DNS address resolution. If Option 6 contains a list of DNS addresses, those addresses are queried in the order given if no response is received from previous addresses on the list. As an alternative to administering DNS by DHCP, you can specify the DNS server and/or Domain name in the HTTP script file. But first SET the

DNSSRVR and DOMAIN values so you can use those names later in the script.

IEEE 802.1X

Certain 1600 Series IP Telephones support the IEEE 802.1X standard for pass-through and Supplicant operation. The system parameter DOT1X

802.1X multicast packets and proxy logoff, as follows:

● When DOT1X = 0, the telephone forwards 802.1X multicast packets from the

Authenticator to the PC attached to the telephone and forwards multicast packets from the attached PC to the Authenticator (multicast pass-through). Proxy Logoff is not supported.

● When DOT1X = 1, the telephone supports the same multicast pass-through as when

DOT1X=0. Proxy Logoff is supported.

● When DOT1X = 2, the telephone forwards multicast packets from the Authenticator only to

the telephone, ignoring multicast packets from the attached PC (no multicast pass-through). Proxy Logoff is not supported.

● Regardless of the DOT1X setting, the telephone always properly directs unicast packets

from the Authenticator to the telephone or its attached PC, as dictated by the MAC address in the packet.

IEEE 802.1X

determines how the telephones handle

All 1600 Series telephones support Supplicant operation and parameter values as specified in IEEE 802.1X, but, as of software Release 1.3, only if the value of the parameter DOT1XSTAT is "1" or "2". If DOT1XSTAT has any other value, Supplicant operation is not supported.

IP telephones will respond to unicast EAPOL frames (frames with the telephone’s MAC address as the destination MAC address, and a protocol type of 88-8E hex) received on the Ethernet line interface if the value of DOT1XSTAT is "1" or "2", but will only respond to EAPOL frames that have the PAE group multicast address as the destination MAC address if the value of DOT1XSTAT is "2". If the value of DOT1XSTAT is changed to "0" from any other value after the Supplicant has been authenticated, an EAPOL-Logoff will be transmitted before the Supplicant is disabled.

As of software Release 1.3, the system parameter DOT1XSTAT determines how the telephone handles Supplicants as follows:

● When DOT1XSTAT=0, Supplicant operation is completely disabled. This is the default

value.

● When DOT1XSTAT=1, Supplicant operation is enabled, but responds only to received

unicast EAPOL messages.

● When DOT1XSTAT=2, Supplicant operation is enabled and responds to received unicast

and multicast EAPOL messages.

Issue 5 April 2010 77

Page 78

Administering Telephone Options

Note:

Note: If the Ethernet line interface link fails, the 802.1X Supplicant, if enabled, enters

the Disconnected state. The 802.1X Supplicant variable userLogoff normally has a value of FALSE. This variable will be set to TRUE before the telephone drops the link on the Ethernet line interface (and back to FALSE after the link has been restored). The userLogoff variable may also be briefly set to TRUE to force the Supplicant into the LOGOFF state when new credentials are entered.

802.1X Pass-Through and Proxy Logoff

1600 Series IP Telephones with a secondary Ethernet interface support pass-through of 802.1X packets to and from an attached PC. This enables an attached PC running 802.1X supplicant software to be authenticated by an Ethernet data switch.

The IP Telephones support two pass-through modes:

● pass-through and

● pass-through with proxy logoff.

The DOT1X parameter setting controls the pass-through mode. In Proxy Logoff mode (DOT1X=1), when the secondary Ethernet interface loses link integrity, the telephone sends an

802.1X EAPOL-Logoff message to the data switch on behalf of the attached PC. The message alerts the switch that the device is no longer present. For example, a message would be sent when the attached PC is physically disconnected from the IP telephone. When DOT1X = 0 or 2, the Proxy Logoff function is not supported

802.1X Supplicant Operation

1600 IP Telephones that support Supplicant operation also support Extensible Authentication Protocol (EAP), but only with the MD5-Challenge authentication method as specified in IETF RFC 3748 [8.5-33a].

A Supplicant identity (ID) and password of no more than 12 numeric characters are stored in reprogrammable non-volatile memory. The ID and password are not overwritten by telephone software downloads. The default ID is the MAC address of the telephone, converted to ASCII format without colon separators, and the default password is null. Both the ID and password are set to defaults at manufacture. EAP-Response/Identity frames use the ID in the Type-Data field. EAP-Response/MD5-Challenge frames use the password to compute the digest for the Value field, leaving the Name field blank.

When a telephone is installed for the first time and 802.1x is in effect, the dynamic address process prompts the installer to enter the Supplicant identity and password. The IP telephone does not accept null value passwords. See “Dynamic Addressing Process” in the Avaya 1600 Series IP Deskphones Installation and Maintenance Guide. The IP telephone stores 802.1X credentials when successful authentication is achieved. Post-installation authentication

Link Layer Discovery Protocol (LLDP)

attempts occur using the stored 802.1X credentials, without prompting the user for ID and password entry.

An IP telephone can support several different 802.1X authentication scenarios, depending on the capabilities of the Ethernet data switch to which it is connected. Some switches may authenticate only a single device per switch port. This is known as single-supplicant or port-based operation. These switches typically send multicast 802.1X packets to authenticating devices.

These switches support the following three scenarios:

● Standalone telephone (Telephone Only Authenticates) - When the IP telephone is

configured for Supplicant Mode (DOT1XSTAT=2), the telephone can support authentication from the switch.

● Telephone with attached PC (Telephone Only Authenticates) - When the IP telephone

is configured for Supplicant Mode (DOT1X=2 and DOT1XSTAT=2), the telephone can support authentication from the switch. The attached PC in this scenario gains access to the network without being authenticated.

● Telephone with attached PC (PC Only Authenticates) - When the IP telephone is

configured for Pass-Through Mode or Pass-Through Mode with Logoff (DOT1X=0 or 1 and DOT1XSTAT=0), an attached PC running 802.1X supplicant software can be authenticated by the data switch. The telephone in this scenario gains access to the network without being authenticated.

Some switches support authentication of multiple devices connected through a single switch port. This is known as multi-supplicant or MAC-based operation. These switches typically send unicast 802.1X packets to authenticating devices. These switches support the following two scenarios:

● Standalone telephone (Telephone Only Authenticates) - When the IP telephone is

configured for Supplicant Mode (DOT1XSTAT=2), the telephone can support authentication from the switch. When DOT1X is "0" or "1", the telephone is unable to authenticate with the switch.

● Telephone and PC Dual Authentication - Both the IP telephone and the connected PC

can support 802.1X authentication from the switch. The IP telephone may be configured for Pass-Through Mode or Pass-Through Mode with Logoff (DOT1X=0 or 1 and DOT1XSTAT=1 or 2). The attached PC must be running 802.1X supplicant software.

Link Layer Discovery Protocol (LLDP)

Release 1.1 1600 Series IP Telephones support IEEE 802.1AB. Link Layer Discovery Protocol (LLDP) is an open standards layer 2 protocol IP Telephones use to advertise their identity and capabilities and to receive administration from an LLDP server. LAN equipment can use LLDP to manage power, administer VLANs, and provide some administration.

The transmission and reception of LLDP is specified in IEEE 802.1AB-2005. The 1600 Series IP Telephones use Type-Length-Value (TLV) elements specified in IEEE 802.1AB-2005, TIA

TR-41 Committee - Media Endpoint Discovery (LLDP-MED, ANSI/TIA-1057), and Proprietary elements. LLDP Data Units (LLDPDUs) are sent to the LLDP Multicast MAC address (01:80:c2:00:00:0e).

These telephones:

● do not support LLDP on the secondary Ethernet interface.

● will not forward frames received with the 802.1AB LLDP group multicast address as the

destination MAC address between the Ethernet line interface and the secondary Ethernet interface.

A 1600 Series IP Telephone initiates LLDP after receiving an LLDPDU message from an appropriate system. Once initiated, the telephones send an LLDPDU every 30 seconds with the following contents:

● DHCP Client is activated.

● The telephone is registered but is not tagging

layer 2 frames with a non-zero VLAN ID.

If VLAN Name causes the telephone to change VLAN and the telephone already has an IP Address the telephone will release the IP Address and reset.

If the TLV VLAN ID matches the VLAN ID the telephone is using, the VLAN ID is marked as set by LLDP. Otherwise, if already registered, the telephone waits until there are no active calls, releases its IP Address, turns on tagging with the TLV VLAN ID, sets L2Q to "on," changes the default L2Q to "on," and resets. If there is no valid IP Address, the telephone immediately starts tagging with the new VLAN ID without resetting.

● the value of USE_DHCP is “0” and the value

of IPADD is not “0.0.0.0”, or

● the Application Type is not 1 (Voice) and is

not 2 (Voice Signaling), or

● the Unknown Policy Flag (U) is set to 1.

MCIPADD will be set to this value if it has not already been set.

TLSSRVR and HTTPSRVR will be set to this value if neither of them have already been set.

L2Q Proprietary 802.1

Q Framing

Proprietary - PoE Conservation TLV

Extended Power-Via-MDI

The default L2Q is set to the value of this TLV. No change is made to the current L2 tagging, but the new default value is used on the next reboot. If TLV = 1, L2Q set to "1" (On). If TLV = 2, L2Q set to "2" (Off). If TLV = 3, L2Q set to "0" (Auto).

This proprietary TLV can initiate a power conservation mode. The telephones that support this will turn on/off the telephone backlight and the backlight of an attached Button Module in response to this TLV.

Power conservation mode will be enabled if the received binary Power Source value is 10, and power conservation mode will be disabled if the received binary Power Source value is not 10. Power conservation mode is enabled even if the telephone is not powered over Ethernet because the telephone sends information about the power source that it is using in a TIA LLDP MED Extended Power-Via-MDI TLV; it is assumed that the power management system intends to conserve local power as well.

Administering Telephone Options

Local Administrative Options Using the Telephone Dialpad

The local procedures you use most often as an administrator are:

● CLEAR - Remove all administered values, user-specified data, option settings, etc. and

return a telephone to its initial “out of the box” default values.

● DEBUG - Enable or disable debug mode for the button module serial port.

● GROUP - Set the group identifier on a per-phone basis.

● RESET - Reset all system values and system initialization values except AUTH, NVAUTH,

registration extension, and password to the default values. Also resets the 802.1X identity and password to the default values.

● VIEW - Review the 1600 IP Telephone system parameters to verify current values and file

versions.

● Ethernet (Hub) Interface Enable/Disable - Enable or disable the Ethernet hub locally.

Clear Procedure

Sometimes, you might want to remove all administered values, user-specified data, and option settings. Essentially, you want to return a telephone to its initial “clean slate” or out of the box condition. This is usually done when passing a telephone to a new, dedicated user when the user’s L O G O F F option is not sufficient. For example, a new user is assigned the same extension, but requires different permissions than the previous user.

The C L E A R option erases all administered data—static programming, file server and call server programming, and user settings including Contact button labels and locally programmed Feature button labels, and restores all such data to default values. The C L E A R option does not affect the software load itself. If you have upgraded the telephone, the telephone retains the latest software. Once you have cleared a telephone, you can administer it normally.

CAUTION:

CAUTION: This procedure erases all administered data, without any possibility of recovering

the data.

Use the following procedure to clear the telephone of its administrative, user-assigned and options values.

1. While the telephone is on-hook and idle, press the following sequence of keys on the faceplate of the telephone:

Mute 2 5 3 2 7 # (Mute C L E A R #)

Static Addressing Installation

The usual way to assign IP addresses to IP telephones is the automatic method. There might be times, however, when manual assignment of IP addresses is desired.

CAUTION:

CAUTION: Static addressing is necessary when a DHCP server is unavailable.

Because of the increased opportunities for text entry errors associated with static addressing, we very strongly recommend that a DHCP server be installed and static addressing avoided.

Use the following procedure to invoke manual address information programming.
