1Introducing the HP Jetdirect Print Server

HP Color LaserJet 3600n/dn printers contain an HP Jetdirect embedded print server that is integrated directly on the printer. Using this print server, you can connect this device directly to a network and share it among multiple users or systems. Because the print server is built into the device, an external port is not needed for network connectivity and may be used for other purposes.

Network Connection

Using the embedded print server and built-in RJ-45 connector, the printer can connect to an IEEE 802.3 10/100Base-TX (Ethernet/Fast Ethernet) network through unshielded twisted-pair network cables.

Auto-negotiation (10/100Base-TX) is used to automatically configure link operation at 10 Mbps or 100 Mbps, and fullor half-duplex communication mode, as required by the network. However, link operation may be manually set using several configuration tools, such as the printer control panel (if supported), Telnet and TFTP commands, a Web browser, and network management software. These tools are described later in this guide.

NOTE Unless otherwise specified, the term print server in this manual refers to an HP Jetdirect print server and not a separate computer running print server software.

Identification

Product Number and Firmware Version

The features and capabilities of an HP Jetdirect print server depends on the print server's product model number and its operating firmware version. The print server in this printer does not support firmware upgrades.

The product model number and operating firmware version are listed on the HP Jetdirect configuration page. The HP Jetdirect configuration page will print when you print the printer's configuration page.

The features and capabilities described in this guide support the following HP Jetdirect print server and firmware version:

ENWW

3 TCP/IP Configuration

To operate properly on a TCP/IP network, the HP Jetdirect print server must be configured with valid TCP/IP network configuration parameters, such as an IP address that is valid for your network. For general information on TCP/IP networks, see TCP/IP Overview.

Server-Based and Manual TCP/IP Configuration

When in a factory-default state and initially powered on, the HP Jetdirect print server will systematically try to obtain its TCP/IP configuration using a server-based method (BOOTP, DHCP, and RARP, described later in this chapter). Up to two minutes are used. If configuration is not successful, a default IP address will be assigned.

The print server may also be configured manually. Manual-based tools include Telnet, a Web browser, the printer control panel, arp and ping commands (when the default IP address is 192.0.0.192), or SNMP-based management software. TCP/IP configuration values assigned manually will be retained when powered off/on.

The print server can be re-configured to use either server-based or manual configuration of TCP/IP settings at any time.

To identify the IP address that is configured on the print server at any time, see the HP Jetdirect configuration page.

Default IP Address

When in a factory-default state (for example, when shipped from the factory or after a cold reset), the HP Jetdirect print server has no IP address. A default IP address may or may not be assigned depending on the network environment.

Default IP Address Will Not Be Assigned

A default IP address will not be assigned if a server-based method (such as BOOTP or DHCP) is successful. And if the print server is powered off/on, the same method will again be used to retrieve IP configuration settings. If this method now fails to retrieve the IP configuration settings (for example, the BOOTP or DHCP server is no longer available), a default IP address will not be assigned. Instead, the print server will continue to send IP configuration requests indefinitely. You must cold-reset the print server to change this behavior.

In addition, a default IP address will not be assigned if a network cable is not attached to the print server.

ENWW

Server-Based and Manual TCP/IP Configuration

Default IP Address Will Be Assigned

A default IP address will be assigned if the factory-default methods fail, or if the print server has just been re-configured by an administrator to use a server-based method (such as BOOTP or DHCP) and it fails.

If a default IP address is assigned, the address will depend on the network to which the print server is connected. The print server senses broadcast packets on the network to determine the appropriate default IP settings:

■On small private networks that adhere to automated, standards-based IP address assignments, the print server uses a link-local addressing technique to assign a unique IP address. Link-local addressing may be referenced as Auto IP. The IP address assigned will be in the range of 169.254.1.0 to 169.254.254.255 (commonly referenced as 169.254/16), and should be valid. However, it can be further modified for your network using supported TCP/IP configuration tools if necessary.

With link-local addresses, subnetting is not used. The subnet mask will be 255.255.0.0, and cannot be changed.

Link-local addresses will not route off the local link, and access to or from the Internet will not be available. The default gateway address will be the same as the link-local address.

If a duplicate address is sensed, the HP Jetdirect print server will automatically reassign its address, if necessary, in accordance with standard link-local addressing methods.

■On large or enterprise IP networks, a temporary address of 192.0.0.192 will be assigned until it is re-configured with a valid address through supported TCP/IP configuration tools. We refer to this address as Legacy Default IP.

■On mixed-environment networks, the self-assigned default IP address may be either 169.254/16 or 192.0.0.192. In this case, you should verify on the Jetdirect configuration page that the assigned default IP address is as expected.

The IP address configured on your print server may be determined by inspecting the Jetdirect configuration page for the print server. See HP Jetdirect Configuration Page.

Default IP Address Configuration Options

Default IP Parameter Options

A Default IP configuration parameter on the print server controls how the default IP address is assigned. Whenever the print server is unable to obtain an IP address during a forced TCP/IP reconfiguration (for example, when manually configured to use BOOTP or DHCP), this parameter will determine the default IP address to use.

When the print server is in a factory-default state, this parameter is undefined.

If the print server is initially configured with a default IP address (either a link-local IP address or the legacy default 192.0.0.192 IP address), the Default IP parameter will be set to either Auto IP or

Legacy Default IP to match.

The Default IP parameter can be changed through a supported configuration tool, such as Telnet, a Web browser, the printer control panel, and SNMP management applications.

10 Chapter 3 TCP/IP Configuration

ENWW

DHCP Requests Enable/Disable

When a default IP address is assigned, you can choose to send, or not send, periodic DHCP requests. DHCP requests are used to retrieve IP configuration settings from a DHCP server on the network. By default, this parameter is enabled, allowing DHCP requests to be transmitted. However, this parameter may be disabled through supported configuration tools such as Telnet, a Web browser, and SNMP management applications.

TCP/IP Configuration Tools

Depending on your printer and operating system, an HP Jetdirect print server can be configured with valid TCP/IP parameters for your network in the following ways:

■Using Software. You can use your printer installation software on supported systems. For more information see HP Software Solutions Summary.

■BOOTP/TFTP. You can download the data from a network-based server using BOOTP (Bootstrap Protocol) and TFTP (Trivial File Transfer Protocol) each time the printer is turned on. For more information, see Using BOOTP/TFTP.

The BOOTP daemon, bootpd, must be running on a BOOTP server that is accessible by the printer.

■DHCP/TFTP. You can use Dynamic Host Configuration Protocol (DHCP) and TFTP (Trivial File Transfer Protocol) each time the printer is turned on. These protocols are supported on HP-UX, Solaris, Linux, Windows NT/2000/Server 2003, NetWare and Mac OS systems. (Refer to your network operating system manuals to verify that your server operating system supports DHCP.) For more information, see Using DHCP.

NOTE Linux and UNIX systems: For more information, see the bootpd man page.

On HP-UX systems, a sample DHCP configuration file (dhcptab) may be located in the / etc directory.

Since HP-UX presently does not provide Dynamic Domain Name Services (DDNS) for its DHCP implementations, HP recommends that you set all print server lease durations to infinite. This ensures that print server IP addresses remain static until such time as Dynamic Domain Name Services are provided.

■RARP. A network-based server can use RARP (Reverse Address Resolution Protocol) to answer the print server's RARP request and supplying the print server with the IP address. The RARP method only allows you to configure the IP address. For more information, see Using RARP.

■arp and ping commands. (For print servers configured with Legacy default IP address 192.0.0.192 only) You can use the arp and ping commands from your system. For more information, see Using the arp and ping Commands.

■Telnet. You can set configuration parameters using Telnet. In order to set configuration parameters, set up a Telnet connection from your system to the HP Jetdirect print server using the default IP address. Once configured, the print server saves the configuration when powered off/on. For more information, see Using Telnet.

■Embedded Web server. You can browse to the embedded Web server on the HP Jetdirect print server to set the configuration parameters. For more information, see Using the Embedded Web Server.

ENWW	Default IP Address 11

■Printer Control Panel. You can manually enter the configuration data using the printer control panel keys. The control panel method allows you to configure only a limited subset of configuration parameters. Therefore, control panel configuration is recommended only during troubleshooting or for simple installations. If control panel configuration is used, the print server saves the configuration when powered off/on. For more information, see Using the Printer Control Panel.

Using BOOTP/TFTP

BOOTP (Bootstrap Protocol) and TFTP (Trivial File Transfer Protocol) provide a convenient way to automatically configure the HP Jetdirect print server for TCP/IP network operation. When powered on, the Jetdirect print server sends a BOOTP request message onto the network. A properly configured BOOTP server on the network will respond with a message that contains basic network configuration data for the Jetdirect print server. The BOOTP server's response may also identify a file that contains extended configuration data for the print server. The Jetdirect print server downloads this file using TFTP. This TFTP configuration file may be located on the BOOTP server, or a separate TFTP server.

BOOTP/TFTP servers are typically UNIX or Linux systems. Windows NT/2000/Server 2003 and NetWare servers can respond to BOOTP requests. Windows NT/2000/Server 2003 servers are configured through Microsoft DHCP services (see Using DHCP). However, Windows NT/2000/Server 2003 systems may require third-party software for TFTP support. For setup of NetWare BOOTP servers, refer to your NetWare documentation.

NOTE If the Jetdirect print server and BOOTP/DHCP server are located on different subnets, IP configuration may fail unless the routing device supports “BOOTP Relay” (allows the transfer of BOOTP requests between subnets).

NOTE While the print server may be configured from systems that support BOOTP/DHCP services, this printer may not support printing from these systems (such as UNIX or NetWare systems).

Why Use BOOTP/TFTP?

Using BOOTP/TFTP to download configuration data has the following benefits:

■Enhanced configuration control of the HP Jetdirect print server. Configuration by other methods, such as a printer control panel, are limited to select parameters.

■Ease of configuration management. Network configuration parameters for the entire network can be in one location.

■Ease of HP Jetdirect print server configuration. Complete network configuration can be automatically downloaded each time the print server is powered on.

NOTE BOOTP operation is similar to DHCP, but the resulting IP parameters will be the same when powered off/on. In DHCP, IP configuration parameters are leased and may change over time.

When in its factory-default state and powered on, the HP Jetdirect print server will attempt to automatically configure itself using several dynamic methods, one of which is BOOTP.

12 Chapter 3 TCP/IP Configuration

ENWW

BOOTP/TFTP on UNIX

This section describes how to configure the print server using BOOTP (Bootstrap Protocol) and TFTP (Trivial File Transfer Protocol) services on UNIX servers. BOOTP and TFTP are used to download network configuration data from a server to the HP Jetdirect print server over the network.

Systems That Use Network Information Service (NIS)

If your system uses NIS, you may need to rebuild the NIS map with the BOOTP service before performing the BOOTP configuration steps. Refer to your system documentation.

Configuring the BOOTP Server

For the HP Jetdirect print server to obtain its configuration data over the network, the BOOTP/TFTP servers must be set up with the appropriate configuration files. BOOTP is used by the print server to obtain entries in the /etc/bootptab file on a BOOTP server, while TFTP is used to obtain additional configuration information from a configuration file on a TFTP server.

When the HP Jetdirect print server is powered on, it broadcasts a BOOTP request that contains its MAC (hardware) address. A BOOTP server daemon searches the /etc/bootptab file for a matching MAC address, and if successful, sends the corresponding configuration data to the Jetdirect print server as a BOOTP reply. The configuration data in the /etc/bootptab file must be properly entered. For a description of entries, see Bootptab File Entries.

The BOOTP reply may contain the name of a configuration file containing enhanced configuration parameters. If the HP Jetdirect print server finds such a file, it will use TFTP to download the file and configure itself with these parameters. For a description of entries, see TFTP Configuration File Entries. Configuration parameters retrieved through TFTP are optional.

NOTE HP recommends that the BOOTP server be located on the same subnet as the printers it serves. BOOTP broadcast packets may not be forwarded by routers unless the routers are properly configured.

Item

nodename

RFC 2132	Description
Option

--The name of the peripheral. This name identifies an entry point to a list of parameters for a specific peripheral. nodename must be the first field in an entry. (In the example above, nodename is “picasso”.)

--The hardware type tag. For the HP Jetdirect print server, set this to ether (for Ethernet). This tag must precede the ha tag.

--The BOOTP report format tag (required). Set this parameter to rfc1048.

--The hardware address tag. The hardware (MAC) address is the link-level, or station address of the HP Jetdirect print server. It can be found on the HP Jetdirect configuration page as the HARDWARE ADDRESS.

--The IP address tag (required). This address will be the HP Jetdirect print server's IP address.

1The subnet mask tag. The subnet mask will be used by the HP Jetdirect print server to identify the portions of an IP address that specify the network/subnetwork number and the host address.

3The gateway IP address tag. This address identifies the IP address of the default gateway (router) that the HP Jetdirect print server will use for communications with other subnets.

6DNS (Domain Name System) server's IP address tag. Only a single name server can be specified.

7The syslog server's IP address tag. It specifies the server that the HP Jetdirect print server sends syslog messages to. For more information, see TCP/IP Overview.

12The host name tag. This tag does not take a value but causes the BOOTP daemon to download the host name to the HP Jetdirect print server. The host name will be printed on the Jetdirect configuration page, or returned on an SNMP sysName request by a network application.

15Domain name tag. Specifies the domain name for the HP Jetdirect print server (for example, support.hp.com). It does not include the host name; it is not the Fully Qualified Domain Name (such as printer1.support.hp.com).

18	Extensions file tag that specifies the relative path name of the TFTP configuration file.

NOTE This tag is similar to the vendor-specific tag T144, described below.

na	44	Tag for IP addresses of the NetBIOS-over-TCP/IP Name Server (NBNS). A primary and
		secondary server may be specified in order of preference.

lease-time	51	DHCP IP address lease duration time (seconds).

tr	58	DHCP T1 timeout, specifying the DHCP lease renewal time (seconds).

tv	59	DHCP T2 timeout, specifying the DHCP lease rebind time (seconds).

T69	69	The IP address (in hexadecimal) of the preferred outgoing e-mail SMTP (Simple Mail
		Transport Protocol) server, for use with supported Scan devices.

T144	--	An HP-proprietary tag that specifies the relative path name of the TFTP configuration file.
		Long path names may be truncated. The path name must be in double quotes (for
		example, “pathname”). For file format information, refer to TFTP Configuration File Entries.

NOTE Standard BOOTP option 18 (extensions file path) also allows a standard tag (ef) to specify the relative path name of the TFTP configuration file.

TCP/IP Other Settings

18 Chapter 3 TCP/IP Configuration

ENWW

Table 3-2 TFTP Configuration File Parameters (continued)

syslog-config:

■ Enables or disables syslog server operation on the print server: 0 disables, 1 (default) enables.

syslog-svr: (or syslog-srv:)

■The syslog server's IP address. It specifies the server that the HP Jetdirect print server sends syslog messages to. For more information, see TCP/IP Overview.

syslog-max:

■Specifies the maximum number of syslog messages that can be sent by the HP Jetdirect print server on a per-minute basis. This setting allows administrators to control the log file size. The default is 10 per minute. If it's set to zero, the number of syslog messages is not restricted.

syslog-priority:

■Controls the filtering of syslog messages sent to the syslog server. The filter range is 0 to 8, with 0 being the most specific and 8 the most general. Only messages that are lower than the filter level specified (or higher in priority) are reported. The default is 8, messages of all priorities are sent. If 0, all syslog messages are disabled.

syslog-facility:

■A code used to identify the source facility of a message (for example, to identify the source of selected messages during troubleshooting). By default, the HP Jetdirect print server uses LPR as the source facility code, but local user values of local0 through local7 can be used to isolate individual or groups of print servers.

slp-config:

■Enables or disables the Service Location Protocol (SLP) operation on the print server: 0 disables, 1 (default) enables.

slp-keep-alive:

■Specifies a time period for the print server to send multicast packets on the network to prevent being deleted from network device tables. Some infrastructure devices, such as switches, may delete active devices from their device tables due to inactivity on the network. To enable this feature, set a value from 1 to 1440 minutes. Set 0 to disable this feature.

ttl-slp:

■Specifies the IP multicast “Time To Live” (TTL) setting for Service Location Protocol (SLP) packets. The default value is 4 hops (the number of routers from the local network). The range is 1–15. When set to a -1, multicast capability is disabled.

mdns-config:

■Enables or disables Multicast Domain Name System (mDNS) services. 0 disables, 1 (default) enables. mDNS is typically used on small networks for IP address and name resolution (through UDP port 5353) where a conventional DNS server is neither used or available.

mdns-service-name:

■Specifies an alphanumeric string of up to 64 ASCII characters assigned to this device or service. This name is persistent and is used to resolve a particular device or service if socket information (such as the IP address) changes from session to session. Apple Rendezvous will display this service. The default service name is the printer model and the LAN Hardware (MAC) address.

ENWW	Using BOOTP/TFTP 19

Table 3-2 TFTP Configuration File Parameters (continued)

mdns-pri-svc:

■Specifies the mDNS highest priority service to use for printing.To set this parameter, choose one of the following printing option numbers:

1: Port 9100 printing

2: IPP port printing

3: The default LPD raw queue

4: The default LPD text queue

5: The default LPD auto queue

6: The default LPD binps (binary postscript) queue

7 through 12: If user-specified LPD queues are defined, corresponds to user-specified LPD queues 5 through 10.

The default selection will depend on the printer, typically port 9100 printing or LPD binps.

ipv4-multicast:

■Enables or disables the receipt and transmission of IP version 4 multicast packets by the print server. 0 disables, 1 (default) enables.

NOTE If this parameter is disabled, other protocols that use multicast protocols, such as mDNS and SLP, may also be disabled without notification.

idle-timeout:

■The number of seconds that an idle print data connection is allowed to remain open. Since the card supports only a single TCP connection, the idle timeout balances the opportunity of a host to recover or complete a print job against the ability of other hosts to access the printer. The acceptable values range from 0 to 3600 (1 hour). If “0” is typed, the timeout mechanism is disabled. The default is 270 seconds.

user-timeout: (or telnet-timeout:)

■An integer (1..3600) that specifies the number of seconds that your Telnet or FTP session can be idle before it will be automatically disconnected. The default is 900 seconds. 0 disables the timeout.

CAUTION Small values, such as 1–5, may effectively disable the use of Telnet. A Telnet session may terminate before any changes can be made.

ews-config: (or web:)

■Enables or disables the print server's embedded Web server to change configuration values: 0 disables, 1 (default) enables.

tcp-mss: (or subnets-local:)

■Specifies the maximum segment size (MSS) that the HP Jetdirect print server will advertise for use when communicating with local subnets (Ethernet MSS=1460 bytes or more) or remote subnets (MSS=536 bytes):

0 (default): All networks are assumed to be local (Ethernet MSS=1460 bytes or more).

1:Use MSS=1460 bytes (or more) for subnets, and MSS=536 bytes for remote networks.

2:All networks are assumed to be remote (MSS=536 bytes), except the local subnet.

MSS affects performance by helping to prevent IP fragmentation that may result in data retransmission.

20 Chapter 3 TCP/IP Configuration

ENWW

Table 3-2 TFTP Configuration File Parameters (continued)

tcp-msl:

■Specifies the maximum segment life (MSL) in seconds. The range is 5–120 seconds. The default is 15 seconds.

telnet-config: (or telnet:)

■If set to 0, this parameter instructs the print server not to allow incoming Telnet connections. To regain access, change the setting in the TFTP configuration file and power cycle the print server, or cold reset the print server to factory default values. If this parameter is set to 1, incoming Telnet connections are allowed.

default-ip:

■Specifies the IP address to use when the print server is unable to obtain an IP address from the network during a forced TCP/IP reconfiguration (for example, when powered off/on or manually configured to use BOOTP/DHCP).

DEFAULT_IP: sets the legacy default IP address 192.0.0.192. AUTO_IP: sets a link-local IP address 169.254.x.x.

The initial setting is determined by the IP address obtained when first powered on.

default-ip-dhcp:

■Specifies whether DHCP requests will be periodically transmitted when a legacy default IP address 192.0.0.192 or linklocal IP address 169.254.x.x has been automatically assigned.

0: Disables DHCP requests.

1 (default): Enables DHCP requests.

dhcp-arbitration:

■Specifies the amount of time, in seconds, that the print server will wait for DHCP configuration offers. A value from 1 to 10 may be set. The default is 5 seconds.

phone-home-config:

■Specifies privacy settings on the print server during embedded Web server access. This command controls whether statistical data on product use may be sent to HP. For HP to collect data, Internet access is required.

2: Prompt the user to allow sending data on initial access to the Networking tab of the embedded Web server. This is the factory-default and cold-reset value. Once changed, this value cannot be re-selected.

1: Allows the sending of data to HP without prompting the user.

0: Disables sending data to HP without prompting the user.

web-refresh:

■Specifies the time interval (1–99999 seconds) for embedded Web server diagnostic page updates. If set to 0, the refresh rate is disabled.

SNMP

snmp-config:

■Enables or disables SNMP operation on the print server. 0 disables, 1 (default) enables SNMP.

CAUTION Disabling SNMP will disable all SNMP agents (SNMP v1, v2c) as well as communications with HP Web Jetadmin. In addition, firmware upgrades through current HP downloading utilities will be disabled.

ENWW	Using BOOTP/TFTP 21

Table 3-2 TFTP Configuration File Parameters (continued)

get-cmnty-name: (or get-community-name:)

■Specifies a password that determines which SNMP GetRequests the HP Jetdirect print server will respond to. This is optional. If a user-specified get community name is set, the print server will respond to either a user-specified community name or the factory-default. The community name must be ASCII characters. The maximum length is 255 characters.

set-cmnty-name: (or set-community-name:)

■Specifies a password that determines which SNMP SetRequests (control functions) the HP Jetdirect print server will respond to. The community name of an incoming SNMP SetRequest must match the print server's “set community name” for the print server to respond. (For additional security, you may limit configuration access through the print server's host access list). Community names must be ASCII characters. The maximum length is 255 characters.

auth-trap: (or authentication-trap:)

■Configures the print server to send (on) or not send (off) SNMP authentication traps. Authentication traps indicate that an SNMP request was received, but the community name check failed. The default is “on.”

trap-dest: (or trap-destination:)

■ Enters a host's IP address into the HP Jetdirect print server's SNMP trap destination list. The command format is:

trap-dest: ip-address [community name] [port number]

The default community name is “public”; the default SNMP port number is “162”. The port number cannot be specified without a community name.

If a “trap-community-name” command is followed by “trap-dest” commands, the trap community name will be assigned to those entries unless a different community name is specified in each “trap-dest” command.

To delete the table, use “trap-dest: 0”.

If the list is empty, the print server does not send SNMP traps. The list may contain up to three entries. The default SNMP Trap Destination List is empty. To receive SNMP traps, the systems listed on the SNMP trap destination list must have a trap daemon to listen to those traps.

Other Settings

link-type:

■Sets the print server's link speed (10, 100 Mbps) and communication mode (Fullor Half-Duplex). The available linkspeed selections are AUTO, 100FULL, 100HALF, 10FULL, 10HALF.

For AUTO (default), the print server uses auto-negotiation to configure itself with the highest link speed and communication mode allowed. If auto-negotiation fails, either 100TX HALF or 10TX HALF is set depending on the detected link speed of the hub/switch port.

Support

support-name: (or support-contact:)

■Typically used to identify the name of a person to contact for support of this device.

support-number:

■Typically used to specify a phone number or extension to call for support of this device.
