Preface xiii

IES-1000 User’s Guide

Chapter 1

Getting

This chapter describes the key features, benefits and applications of your IES-1000.

The IES-1000 is an integrated Ethernet switch that allows you to multiplex traffic from up to 16 G.SHDSL or
ADSL subscribers (or eight of each) to an Ethernet network using existing phone line wiring before it is
forwarded to the Internet. When deployed together with ZyXEL’s DSL modems and WAN routers, the
combination forms an integrated solution for providing broadband services to multiple tenant units such as
apartments, hotels, offices and campus buildings.

G.SHDSL is an acronym for Single-pair High-speed Digital Subscriber Line. ITU-T G.991.2 defines the “G.” in
“G.SHDSL”.

ADSL is an acronym for Asymmetric Digital Subscriber Line.

to Know the IES-1000

1.1 Features

Two-Slot Chassis

The IES-1000 has two slots that accept multiplexer network modules. The chassis design gives you the flexibility
to initially install a single module and then add another as demand increases.

Multiplexer Network Modules

Up to two hot-swappable multiplexing network modules may be installed in each IES-1000 chassis.

The SAM1008 (G.SHDSL Access Module) is an 8-port G.SHDSL multiplexer network module that aggregates
traffic from eight lines to an Ethernet port.

The AAM1008 (ADSL Access Module) is an 8-port ADSL multiplexer network module that aggregates traffic
from eight lines to an Ethernet port and has integrated splitters to allow voice and ADSL to be carried over the
same phone line wiring.

10/100 Mbps Auto-negotiating Ethernet Port

This 10/100 Mbps auto-negotiating Ethernet port connects the IES-1000 to an Ethernet network. With Ethernet as
the backbone, you can create a network that provides G.SHDSL and or ADSL service to hundreds of subscribers.

G.SHDSL Compliance (SAM1008)

• ITU-T G.991.2

• G.hs (ITU-T G.994.1)

• Rate adaptation support

ADSL Compliance (AAM1008)

• Multi-Mode ADSL standard

 G.lite (ITU-T G.992.2)

 G.hs (ITU-T G.994.1)

 ANSI T1.413 issue 2

• Rate adaptation support

Port Bonding (SAM1008)

The port bonding feature allows you to combine two to four G.SHDSL connections between two IES-1000s into a
single logical connection. This can give increased bandwidth for LAN-to-LAN applications.

Bridging

• IEEE 802.1D transparent bridging

• Up to 4096 MAC entries address table

• Port-based VLAN (Virtual Local Area Network)

IEEE 802.1Q Tagged VLAN

Your IES-1000 uses the IEEE 802.1Q Tagged VLAN (Virtual Local Area Network), which allows your device to
deliver tagged/untagged frames to and from its ports. The IES-1000 supports up to 255 VLANs and up to 4094
VLAN IDs.

IEEE 802.1p Priority

Your IES-1000 uses IEEE 802.1p Priority to assign priority levels to individual ports.

Fast Mode

The fast mode makes use of the “tag” subset of the IEEE 802.1Q standard to identify the source port of a frame
and speed traffic through a service gateway.

MAC (Media Access Control) Filtering

Use MAC filter commands to filter incoming frames based on MAC (Media Access Control) address(es) that you
specify. You may enable/disable specific ports. You may specify up to five MAC addresses per port.

Secured Host

Allow up to ten remote hosts to access your IES-1000 via IP addresses you specify.

System Error Logging

The system error log will record error logs locally to the IES-1000 memory. These logs may be viewed again after
a warm restart.

UNIX Syslog Logging

Use UNIX syslog commands to send logs to your UNIX server.

Protocol

• Multiple Protocols over AAL5 (RFC 1483)

1-2 Getting to Know the IES-1000

IES-1000 User’s Guide

Management

• Remote configuration backup/restore and firmware upgrade

• SNMP manageable

• Text-based management locally via console port and remotely via telnet

• Web configurator with online help

Security

• Password protection for system management

• VLAN

IGMP Snooping

IGMP (Internet Group Management Protocol) snooping reduces multicast traffic for maximum performance.

Overheating Detection, Warning and Safegaurd

An ALM LED turns on when the IES-1000’s internal temperature is too high and turns off when the temperature
has returned to a normal level. Internal fans cool the unit.

Compact Design for Limited Space

The IES-1000 occupies only 1 U of standard Telco rack space. Its compactness is perfect for collocation
(installation in a central office) and basement installation.

Scalable Platform for Future Expansion

The flexible design of the IES-1000 series allows service providers to start with minimum cost. As the number of
subscribers and applications increases additional IES-1000s can be added to provide greater bandwidth.

1.2 Physical Specifications

1.2.1 Physical Interfaces

1.3 Applications

1.3.1 MTU Application

The following figure depicts a typical application of the IES-1000 is in a large residential building, or multiple
tenant unit (MTU), that leverages the existing phone line wiring to provide Internet access to all tenants.

A tenant connects a computer to the phone line in a unit using a G.SHDSL or ADSL modem. The other end of the
phone line is connected to a port on the IES-1000. The IES-1000 aggregates the traffic from tenants to the
Ethernet port and then forwards it to a router. The router then routes the traffic further to the Internet.

IES-1000 User’s Guide

2.3 Front Panel Connections

2.3.1 LAN Port (Ethernet)

Connect the LAN port of the network module to an Ethernet switch using a straight-through category 5 UTP
(Unshielded Twisted Pair) cable with RJ-45 connectors if you are connecting to a hub or switch. Use a crossover
cable if you are connecting to a single computer.

2.3.2 CONSOLE Port

For initial configuration, you need to use terminal emulator software on a computer and connect it to the network
module through the console port. Connect the RJ-11 connector on one end of the RS-232 console cable to the
console port of the network module. Connect the DB-9 connector on the other end of the console cable to a serial
port (COM1, COM2 or other COM port) of your computer. You can use an extension cable if the enclosed one is
too short. After the initial setup, you can modify the configuration remotely through Telnet.

2.3.3 Ports 1-8 (SAM1008 Ports)

To complete a G.SHDSL connection, connect a telephone line from the subscriber equipment to one of the
SHDSL ports on the SAM1008.

2.3.4 Ports 1-8 (AAM1008 Ports)

The line from the subscriber carries both the ADSL and the voice signals. For each line, the AAM1008 has a
built-in splitter that separates the high frequency ADSL signal from the voice band signal and feeds the ADSL
signal to the AAM1008, while the voice band signal is diverted to the CO port.

To complete an ADSL connection, connect a telephone line from the subscriber equipment to one of the upper
ADSL ports on the AAM1008. Connect a telephone line from one of the lower ADSL ports on the AAM1008 to
the CO switch or PBX (Private Branch Exchange).

2.3.5 POWER Port

Connect the female end of the power cord to the power receptacle on the front panel of your IES-1000. Connect
the other end of the cord to a power outlet. Make sure that no objects obstruct the airflow of the fans. If you are
facing the IES-1000 front panel, the fan vents are located on the left side of the unit.

Make sure you are using a 100 - 240 VAC, 50/60 Hz power source.

System

This section describes basic configuration and system-related commands.

Commands

5.1 Command Line Interface (CI)

The IES-1000 uses text command lines as the user interface for software configuration. Before discussing the
details of configuration, the rules of the commands are listed next.

The command keywords are in courier new font.

1. The command keywords must be entered exactly as shown, that is, no abbreviations are allowed.

2. The required fields in a command are enclosed in angle brackets (<>), for instance,

list port <port #>

means that you must specify the port number for this command.

3. The optional fields in a command are enclosed in square brackets ([]), for instance,

config [save]

means that the save field is optional.

4. A “|” means “or”

[on|off]

means that you can use either on or off.

5. “Command” refers to a command used in the command line interface (CI command).

Using commands not documented in this User’s Guide can damage the unit and possibly render

it unusable.

5.2 Console Connection

For the initial configuration, you must use the console port. After the initial setup, you can telnet to the system and
perform additional management tasks. Connect the RJ-11 connector on one end of the RS-232 console cable to the
console port of the network module. Connect the DB-9 connector on the other end of the console cable to a serial
port (COM1, COM2 or other COM port) of your computer. You can use an extension cable if the enclosed one is
too short. After the initial setup, you can modify the configuration remotely through Telnet

You can use any terminal emulation program (Windows’ built-in HyperTerminal for example) with the following
parameters:

• VT100 terminal emulation

• 9600 bps

System Commands 5-1

IES-1000 User’s Guide

• No parity, 8 data bits, 1 stop bit

• No flow control

5.3 Command Structure

The system uses a two-level command structure. The commands related to one subsystem are grouped under a
primary command of that subsystem, for instance, to configure the Ethernet parameters, you must first enter the
Ethernet subsystem by entering the ethernet command. When you are in a subsystem, the system reminds you
by including the subsystem name in the command prompt, for example,

192.168.1.1 ethernet>

To get back to the top level prompt from a subsystem, use the home command.

The remainder of this User’s Guide describes CI Commands that are helpful for configuring

network modules.

5.3.1 Help Facility

The system includes a help facility to provide you with online assistance.

You can issue the help or ? command at any time. The system will display a list of available commands in
response.

You can issue help with a command name to get more details about it, for instance, the command

192.168.1.1> help version

yields

G.SHDSL

The G.SHDSL (G.991.2 Single-pair High-speed Digital Subscriber Line) subsystem allows you to

configure and monitor the G.SHDSL ports on the SAM1008 network module.

Commands

6.1 G.SHDSL Standards

The IES-1000 supports both G.991.2 and the G.hs standards.

Table 6-1 Data Rates of the SAM1008’s SHDSL Ports

STANDARD MAXIMUM UPSTREAM AND

DOWNSTREAM RATE

G.991.2 2304 Kbps 192 Kbps

MINIMUM UPSTREAM AND

DOWNSTREAM RATE

6.2 Profiles

A profile is a table that contains a list of pre-configured SHDSL settings. Each G.SHDSL port has one (and only
one) profile assigned to it at any given time. The profile defines the maximum and minimum transfer rates, of all
the G.SHDSL ports that have this profile. You can configure multiple profiles, including profiles for
troubleshooting.

Profiles allow you to configure G.SHDSL ports efficiently. You can configure all of the G.SHDSL ports with the
same profile by modifying the profile, thus removing the need to configure the G.SHDSL ports one-by-one. You
can also change an individual G.SHDSL port by assigning it a different profile.

For example, you could set up different profiles for different kinds of accounts (say economy, standard and
premium). Assign the appropriate profile to a G.SHDSL port and it takes care of a large part of the port’s
configuration. You still get to individually enable or disable each port, as well as configure its encapsulation type,
multiplexing mode, VPI and VCI. See later in this chapter for how to configure profiles.

6.3 Configured Versus Actual Speed

You configure the maximum and minimum speed of individual G.SHDSL ports using the set profile

command. However, due to noise and other factors on the line, the actual speed may not reach the maximum that
you specify.

Even though you can specify arbitrary numbers in the set profile command, the actual speed is always a
multiple of 64 Kbps. If you enter a speed that is not a multiple of 64 Kbps, the actual speed will be the next lower
multiple of 64Kbps. For instance, if you specify 600 Kbps for a port, the actual speed for that port will not exceed
576 Kbps, and if you specify 660 Kbps, the actual speed will not be over 640Kbps.

Note that when you configure a G.SHDSL port, the upstream and downstream speeds are the same. The list
port command displays the configured parameters and actual speed of a G.SHDSL port.

G.SHDSL Commands 6-1

IES-1000 User’s Guide

6.4 Port Bonding

The port bonding feature allows you to send IP packets over two to four G.SHDSL connections as a single
connection. This can give increased bandwidth in LAN-to-LAN applications between IES-1000s.

You can easily select two to four G.SHDSL ports to bond together. IES-1000 checks the transfer rates of the
individual G.SHDSL ports when they connect. The IES-1000 retrains any of the bonded ports that have a lower
speed up to three times in an attempt to get them to reach the higher speed. If a port does not reach the higher
speed (or at least within a 640 Kbps tolerance of the higher speed) by the third attempt, that port is dropped.

You can bond multiple groups of ports on a single IES-1000 (or even within a single SAM1008 module) as long
as they do not overlap.

6.5 Default Settings

The default profile always exists and all of the G.SHDSL ports belong to it when the SAM1008 is shipped. The
default profile's name is set to DEFVAL.

6.5.1 Default Profile Settings

The following are the settings of the default profile.

• Name: DEFVAL

• Minimum Transmission Rate: 192 Kbps

• Maximum Transmission Rate: 2304 Kbps

6.6 G.SHDSL Commands

The commands related to one subsystem are grouped under a primary command of that subsystem, for instance, to
configure the G.SHDSL parameters, you must first enter the G.SHDSL subsystem by entering the gshdsl
command as shown next.

G.SHDSL Commands 6-5

IES-1000 User’s Guide

This command shows the configured minimum speeds (if applicable), maximum speeds, states and statuses of all
G.SHDSL ports. Here is a description of the various status field messages:

Failed =

Dropped =

BondC =

BondR =

Normal =

The system was unable to download firmware to the DSL chipset.

The port is a member of a bonded group but was dropped because it could not connect
within at least 640 Kbps of the rate of the other bonded ports. Both the central and remote
sides of the connection must disable and re-enable the dropped port to attempt to bring up
the connection again.

The port is connected and functioning as part of a central side group of bonded ports. See
the Set Central Side Port Bonding Command section.

The port is connected and functioning as part of remote side group of bonded ports. See
the Set Remote Side Port Bonding Command section.

where

<name> =

<Cmax> =

<Cmin> =

The name of the profile (up to 18 characters except DEFVAL).

The maximum transmission rate in Kbps.

The minimum transmission rate in Kbps. This setting is optional. 192 Kbps is the
default if you do not configure a value for this parameter. Setting Cmax and Cmin to
the same rate fixes the rate for that port.

Configure <Cmax> and <Cmin> parameters between 192 and 2304 Kbps.

Speed Configuration

Even though you can specify arbitrary numbers for port speeds using the set profile command, the

SAM1008 port speed is always adjusted to be a multiple of 64 Kbps. If you enter a speed that is not a multiple of
64 Kbps, the SAM1008 will use the next lower multiple of 64 Kbps. For instance, if you specify 600 Kbps for a
port, the SAM1008 port will not exceed 576 Kbps; if you specify 660 Kbps, the SAM1008 port will not exceed
640 Kbps. See the examples shown next.

Example 1:

The configuration

192.168.1.1 gshdsl> set profile economy 2000 200

sets the speed for the economy profile between 1984 and 192 Kbps.

ADSL

The ADSL (Asymmetrical Digital Subscriber Line) subsystem allows you to configure and monitor the

ADSL ports on the AAM1008 network module.

Commands

7.1 ADSL Standards

The AAM1008 supports both the G.lite and the G.dmt standards. G.lite is intended to minimize the cost for the
consumer market.

Table 7-1 Maximum Transfer Rates of the AAM1008’s ADSL Ports

STANDARD MAXIMUM DOWNSTREAM MAXIMUM UPSTREAM

G.dmt 8160 Kbps 1024 Kbps

G.dmt Annex B 8160 Kbps 1024 Kbps

G.lite 1536 Kbps 512 Kbps

ANSI T1.413 issue 2 8160 Kbps 1024 Kbps

7.2 Profiles

A profile is a table that contains a list of pre-configured ADSL settings. Each ADSL port has one (and only one)
profile assigned to it at any given time. The profile defines the maximum and minimum upstream/downstream
rates, the target upstream/downstream signal noise margins, and the maximum and minimum
upstream/downstream acceptable noise margins of all the ADSL ports that have this profile. You can configure
multiple profiles, including profiles for troubleshooting.

Profiles allow you to configure ADSL ports efficiently. You can configure all of the ADSL ports with the same
profile by modifying the profile, thus removing the need to configure the ADSL ports one-by-one. You can also
change an individual ADSL port by assigning it a different profile.

For example, you could set up different profiles for different kinds of accounts (say economy, standard and
premium). Assign the appropriate profile to an ADSL port and it takes care of a large part of the port’s
configuration. You still get to individually enable or disable each port, as well as configure its encapsulation type,
multiplexing mode, VPI, VCI and operational mode. See later in this chapter for how to configure profiles.

7.3 Configured Vs. Actual Rate

You configure the maximum rate of an individual ADSL port by modifying its profile (see the set profile
command) or assigning the port to a different profile (see the set port command). However, due to noise and
other factors on the line, the actual rate may not reach the maximum that you specify.

ADSL Commands 7-1

IES-1000 User’s Guide

Even though you can specify arbitrary numbers in the set profile command, the actual rate is always a
multiple of 32 Kbps. If you enter a rate that is not a multiple of 32 Kbps, the actual rate will be the next lower
multiple of 32Kbps. For instance, if you specify 60 Kbps for a port, the actual rate for that port will not exceed 32
Kbps, and if you specify 66 Kbps, the actual rate will not be over 64Kbps.

Note that when you configure an ADSL port, the upstream rate must be less than or equal to the downstream rate.
Note also that the list port command displays the configured parameters of the ADSL port, while the show
port command displays the actual rates.

7.4 Default Settings

The default profile always exists and all of the ADSL ports belong to it when the AAM1008 is shipped. The
default profile's name is set to DEFVAL. The default profile’s maximum downstream rate can only be obtained
when using the G.dmt standard. Configure a profile with a maximum downstream rate of 1536 Kbps or less for
use with G.lite.

7.4.1 Default Profile Settings

The following are the settings of the default profile.

• Name: DEFVAL

• Profile Status: Active

Downstream ADSL settings:

• Target Signal/Noise Rate: 6 db

• Maximum Signal/Noise Rate: 31 db

• Minimum Signal/Noise Rate: 0 db

• Minimum Transmission Rate: 32 Kbps

• Maximum Transmission Rate: 2048 Kbps

Upstream ADSL settings:

• Target Signal/Noise Rate: 6 db

• Maximum Signal/Noise Rate: 31 db

• Minimum Signal/Noise Rate: 0 db

• Minimum Transmission Rate: 32 Kbps

• Maximum Transmission Rate: 512 Kbps

7.4.2 Other Default Settings

The factory default settings for all ADSL ports of the AAM1008 are

• Encapsulation: RFC 1483

ATU-C (atuc) stands for ADSL Termination Unit-Central and refers to downstream transmission and ATU-R
(atur) stands for ADSL Termination Unit-Remote and refers to upstream transmission.

The profile is a table that contains information on ADSL line configuration. Each entry in this table reflects a
parameter defined by a manager, which can be used to configure the ADSL line.

Note that the default value will be used for any of the above fields that are omitted.

The upstream rate must be less than or equal to the downstream rate.

Even though you can specify arbitrary numbers in the set profile command, the actual rate is always a
multiple of 32 Kbps. If you enter a rate that is not a multiple of 32 Kbps, the actual rate will be the next lower
multiple of 32Kbps. For instance, if you specify 60 Kbps for a port, the actual rate for that port will not exceed 32
Kbps, and if you specify 66 Kbps, the actual rate will not be over 64Kbps.

An example is shown next.

192.168.1.1 adsl> set profile debug 800 8000

10/100M

The Ethernet subsystem allows you to configure and monitor the 10/100M fast Ethernet port.

Fast Ethernet Port Commands

8.1 10/100M Auto-Sensing Ethernet

The IES-1000 supports 10/100Mbps auto-negotiating Ethernet. There are two factors related to the connection of
two Ethernet ports: speed and duplex mode. In a 10/100Mbps fast Ethernet, the speed can be 10Mbps or 100Mbps
and the duplex mode can be half duplex or full duplex. The auto-negotiation capability makes one Ethernet port
able to negotiate with a peer automatically to obtain the optimal connection speed and duplex mode.

When auto-negotiation is turned on, the Ethernet port of the IES-1000 negotiates with the peer Ethernet port on
the Ethernet cable automatically to determine the optimal connection speed and duplex mode. If the peer Ethernet
port does not support auto-negotiation or turns off this feature, the IES-1000 determines the connection speed by
detecting the signal on the cable and using half duplex mode. When the IES-1000’s auto-negotiation is turned off,
the Ethernet port uses the pre-configured speed and duplex mode settings when making a connection, thus
requiring you to check the settings of the peer Ethernet port in order to connect.

8.2 Ethernet Commands

8.2.1 Set Auto Command

Syntax:

192.168.1.1 ethernet> set auto <on|off>

where

<on|off> = on or off

Bridge

This chapter discusses the bridge subsystem. It allows you to configure and monitor the bridging,

configure MAC filters, port-based VLANs and tagged frame functions of the IES-1000.

The IES-1000 supports IEEE 802.1D transparent bridging; but not the static filtering feature or spanning tree
protocol. The bridge learns the source MAC addresses of sender hosts by inspecting incoming Ethernet frames
and recording the learned MAC addresses with their incoming port numbers into its filtering database. Based on
the database, the bridge forwards each incoming frame to its destination port.

Commands

9.1 IGMP Snooping

Traditionally, IP packets are transmitted in one of either two ways - Unicast (1 sender to 1 recipient) or Broadcast
(1 sender to everybody on the network). Multicast delivers IP packets to just a group of hosts on the network.

IGMP (Internet Group Multicast Protocol) is a session-layer protocol used to establish membership in a multicast
group - it is not used to carry user data. Refer to RFC 1112 and RFC 2236 for information on IGMP versions 1
and 2 respectively.

A layer-2 switch can passively snoop on IGMP Query, Report and Leave (IGMP version 2) packets transferred
between IP multicast routers/switches and IP multicast hosts to learn the IP multicast group membership. It checks
IGMP packets passing through it, picks out the group registration information, and configures multicasting
accordingly.

Without IGMP snooping, multicast traffic is treated in the same manner as broadcast traffic, that is, it is forwarded
to all ports. With IGMP snooping, group multicast traffic is only forwarded to ports that are members of that
group. IGMP Snooping generates no additional network traffic, allowing you to significantly reduce multicast
traffic passing through your switch.

9.2 Bridge Port Numbers

The bridge subsystem of the IES-1000 defines its own numbering convention for ports.

The bridge has a total of nine ports: bridge port 1 stands for the Ethernet port, bridge port 2

stands for DSL port 1, bridge port 3 stands for DSL port 2, and so on.

Be sure you have clarified the relation between bridge ports and DSL ports.

9.6 Port-Based VLAN Commands

The IES-1000 VLAN (Virtual Local Area Network) mechanism can be used to limit the broadcast domain to the
members of a VLAN group only. In this way, VLAN increases network performance by limiting broadcasts to a
smaller and more manageable logical broadcast domain. In traditional switched environments, all broadcast
frames go to each and every individual port.

The stations on a logical network belong to one group; however, a station can belong to more than one group.
Subscribers of one group are not allowed to access the resources of other groups and a higher level of security is
achieved. This isolates the subscribers from one another and prevents a subscriber from discovering the resources,
for example, shared drives or printers, of another subscriber.

In the IES-1000 port-based VLAN, the allowable outgoing port(s) of each incoming port must be defined.
Ethernet frames are forwarded according to these rules. Therefore, if you wish to allow two subscriber ports to
talk to each other, for example, between conference rooms in a hotel, you must define the egress port (outgoing
port) for both ports. An egress port is an outgoing port, that is, a port through which a data frame leaves. Port­based VLANs are specific only to the switch on which they were created.

The factory default settings for the port-based VLAN of the IES-1000 are:

- Bridge port 1 (Ethernet port) allowed to all bridge ports

- Bridge port 2 (DSL port 1) allowed to bridge port 1 (Ethernet port) only

- Bridge port 3 (DSL port 2) allowed to bridge port 1 (Ethernet port) only

- Bridge port 4 (DSL port 3) allowed to bridge port 1 (Ethernet port) only

- Bridge port 5 (DSL port 4) allowed to bridge port 1 (Ethernet port) only

- Bridge port 6 (DSL port 5) allowed to bridge port 1 (Ethernet port) only

- Bridge port 7 (DSL port 6) allowed to bridge port 1 (Ethernet port) only

- Bridge port 8 (DSL port 7) allowed to bridge port 1 (Ethernet port) only

- Bridge port 9 (DSL port 8) allowed to bridge port 1 (Ethernet port) only

The default VLAN settings allow each DSL port to communicate back and forth with only the Ethernet port, and
not with other DSL ports. The following figure illustrates this.

9-6 Bridge Commands

Bridge Commands 9-7

IES-1000 User’s Guide

This example sets the allowed outgoing bridge ports of port 2 (DSL port 1) to port 1 (Ethernet port) and port 3
(DSL port 2). The allowed outgoing bridge ports of port 3 (DSL port 2) are set to port 1 (Ethernet port) and port
2 (DSL port1). This way, DSL ports 2 and 3 can communicate with each other and the Ethernet port. You can
see the effects of this example by using the following command:

192.168.1.1 bridge> portfilter

Port 1 (ethernet): all

Port 2 (dsl1): 1 3

Port 3 (dsl2): 1 2

9.7 Tagged Ethernet Frames Commands (Fast Mode)

The network module’s fast mode makes use of the “tag” subset of the IEEE 802.1Q standard to identify the source
port of an Ethernet frame and speed traffic through a service gateway. In this way, the source port of a frame can
be recognized across switches. Fast mode reduces overhead by basing the forwarding decisions on the 802.1Q tag
instead of checking and filtering MAC addresses. Fast mode allows only one port per PVID. Use normal mode
(see 5.5.5) and the 802.1Q VLAN commands (see Chapter 10 ) to configure VLANs or PVIDs with multiple ports.

9.7.1 FPVID Command

Syntax:

where

192.168.1.1 bridge> fpvid [<port> <vid>]

<port> =

The port number on the network module. Port 0 is the CPU’s port, port 1 is the
Ethernet port and ports 2-9 are the bridge ports on network module modules.
These are logical ports.

Bridge Commands 9-9

IES-1000 User’s Guide

<vid> =

The tag number (or IEEE 802.1Q identification) that identifies the source port of
an Ethernet frame. Allocate tag numbers for all logical ports on your network
module.

This command lets you allocate IEEE 802.1Q identification numbers (tags) on a port-by-port basis.

The command 192.168.1.1 bridge> fpvid displays the default port identification of all network
module ports.

The IEEE 802.1Q standard uses an explicit tag in the header to specify the VLAN ID (VID) of an Ethernet frame.
In this way, the VLAN membership of a frame can be carried across switches. The following table displays the
physical port and corresponding default PVID tag on the IES-1000.

10.1 Introduction

The IEEE 802.1Q Tagged VLAN allows your network module to deliver tagged/untagged frames to and from its
ports. The standard gives the network module the ability to recognize VLAN-aware and VLAN-unaware devices
and automatically strips tags from frames destined for ports that would normally drop tagged frames.

10.2 IEEE 802.1Q Tagged VLAN -Tags

When a LAN bridge receives a frame from a workstation, the VLAN from whence it came must be known so the
bridge may respond, if necessary, to the source of the frame. This is accomplished by tagging. There are two kinds
of tagging:

1. Explicit Tagging

• A VLAN identifier is added to the frame header that identifies the source VLAN.

2. Implicit Tagging

• The MAC (Media Access Control) number, the port or other information is used to identify the source of a
VLAN frame.

The IEEE 802.1Q Tagged VLAN uses both explicit and implicit tagging.

10.3 VLAN-Aware/VLAN-Unaware Devices

It is important for the LAN bridge to determine what devices are VLAN-aware and VLAN-unaware, so that it can
decide whether to forward a tagged frame (to a VLAN-aware device) or first strip the tag from a frame and then
forward it (to a VLAN-unaware device).

10.4 Filtering Databases

A filtering database stores and organizes VLAN registration information useful for switching frames to and from a
LAN bridge. A filtering database consists of a static entries (Static VLAN or SVLAN table) and dynamic entries
(Dynamic VLAN or DVLAN table).

10.4.1 Static Entries (SVLAN Table)

Static entry registration information is added, modified and removed by management only.

IEEE 802.1Q Tagged VLAN Commands 10-1

IES-1000 User’s Guide

10.4.2 Dynamic Entries (DVLAN Table)

Dynamic entries are learned by the bridge and cannot be created or updated by management. The bridge learns
this information by observing what port, source address and VLAN ID (or VID) is associated with a frame.
Entries are added and deleted using GARP VLAN Registration Protocol (GVRP), where GARP is the Generic
Attribute Registration Protocol.

10.5 Configuring the Tagged VLAN

In a typical setup, each DSL port is assigned a different VLAN ID (VID) to isolate the subscribers, while the
uplink port should be a member of every subscriber VID and the management VID. The port-based VLAN is
always active; it is NOT mutually exclusive of the tag-based VLAN. The system performs tagged-VLAN
processing first and then port-based VLAN in tandem.

The deletion of the default management VLAN and the enabling of the VLAN MUST be the last steps in the
configuration procedure, because once you change the settings, you will not be able to connect to the network
module with your computer, which is without tagged VLAN capability. You can configure the VLAN associated
with the DSL ports before the uplink ports, or you can do this over the network after the network module is put
into service.

See the examples with the following procedure.

Procedure:

Step 1. Use the IEEE 802.1Q tagged VLAN commands to configure tag-based VLAN for the subscribers.

• Use the svlan setentry command to configure a VLAN ID for each subscriber.

 For a typical setup, use “fixed” for the administration control for the DSL port (numbered 2-9)

and the uplink port (number 1).

 Select “untag” for the tag control for the DSL port and “tag” for the uplink port.

 Ignore any messages telling you to use the enable vlan command in order to enable GVRP.

Use the enable vlan command when you are finished configuring the VLAN (see the last
step).

• Use the pvid command to set the VLAN ID you created for a port to that specific port in the PVID
table.

• Repeat these steps for the rest of the DSL ports.

Configure your management VLAN.

• Use the svlan setentry command to configure a VLAN ID for your device (the “management” or
“CPU” VLAN.

• Use the svlan cpu command to register your device as a member of the management VLAN.

Example:

1.

2.

Step 2.

192.168.1.1 vlan1q> svlan setentry 2 1 fixed tag

192.168.1.1 vlan1q> svlan cpu 2

Perform the procedure below to complete the VLAN setup after you have configured all the network
modules in the chassis. Note that this must be the last step before you lose the connection to the
network module.

a. Telnet to the operational IP address of a network module.

b. Use the svlan delentry command to remove the default VLAN ID (1).

c. Use the vlan enable command to activate the VLAN after you have finished all of your

configuration.

Forwarding Process Example

The switch uses the SVLAN in making frame-forwarding decisions.

First the switch checks the MAC address in a frames header against the MAC filtering database.

Next the switch checks the VLAN ID (VID) of tagged frames or assigns temporary VIDs to untagged frames (see
the PVID Command).

The switch then checks the VID in a frame’s tag against the SVLAN table.

The switch notes what the SVLAN table says (that is, the SVLAN tells the switch whether or not to forward a
frame and if the forwarded frames should have tags).

Then the switch applies the port filter to finish the forwarding decision. This means that frames may be dropped
even if the SVLAN says to forward them. Frames might also be dropped if they are sent to a CPE (customer
premises equipment) DSL device that does not accept tagged frames.

The following figure shows the flow of the decision process used with a broadcast frame (one that is meant to go
to all of the ports).

IEEE 802.1Q Tagged VLAN Commands 10-7

IES-1000 User’s Guide

Figure 10-4 SVLAN Example

An untagged frame comes in from the LAN.

The switch checks the PVID table and assigns a temporary VID of 1.

The switch ignores port# 1 (the LAN port where the frame came in), because the switch does not send a frame to
the port that it came in through.

The switch sees that port #s 2, 3, 4, 6, 8 and 9 (DSL ports 1, 2, 3, 5, 7 and 9) are all set to “fixed” and “untag”
which means the SVLAN allows the frame to be sent to those ports without a tag.

Port # 5 is “forbidden” so the frame is not forwarded to DSL port # 4.

Port # 7 (DSL port 6) is “normal” which means that it was entered dynamically, so the frame is permitted to be
forwarded to port # 7 if port # 7 is registered in the DVLAN table.

After looking at the SVLAN, the switch sees that the port filter is set for port 1 (the LAN port) to forward frames
to all of the ADSL ports, so the switch forwards everything that the SVLAN permits.

Please note that the switch also sends the frame to “CPU” (the switch itself), because the switch is a member of
this VLAN. The switch can be a member of only one VLAN at a time.

802.1p Priority Commands

This chapter explains IEEE 802.1p Priority CI Commands.

11.1 Introduction

IEEE 802.1p Priority CI Commands assign priority levels to individual ports. IEEE 802.1p defines up to eight
priorities (0-7) by inserting a tag into a MAC-layer frame that contains bits to define priority of service.

11.2 IEEE 802.1p Priority Commands

Bridge port 1 stands for the Ethernet port, bridge port 2 stands for DSL port 1, bridge port 3

stands for DSL port 2, and so on.

11.2.1 Priority Port Command

Syntax:

192.168.1.1 vlan1q> priority port <port #> <priority>

where

This command sets the default priority that is assigned to untagged frames from a specified ingress port.

To display the default port priority table, simply use the Priority Port command without parameters, as
shown next.

<port #> =

<priority> =

192.168.1.1 vlan1q> priority port

A bridge port number. Valid parameter range = [1 - 9].

The default priority for the specified port. Valid parameter range = [0 - 7],
where 0 is the lowest priority and 7 is the highest priority.

11.2.2 Regen Port Command

Syntax:

192.168.1.1 vlan1q> regen port [<port #> <user priority> <regened
priority>]

where

<port #> =

<user priority> =

A bridge port number. Valid parameter range = [1 – 9].

The user priority for a frame received on this port. Valid
parameter range = [0 – 7 or *], where 0 is the lowest priority, 7 is
the highest priority and * means all user priorities.

<regened priority> =

The regenerated user priority the incoming user priority is
mapped to for <port #>. Valid parameter range = [0 - 7],
where 0 is the lowest priority and 7 is the highest priority.

This command changes the priority of a tagged frame from a specified ingress port from the original user
priority to the regened priority.

IP

Commands

This chapter shows you how to configure the IP (Internet Protocol) parameters. The IP host

implementation in the IES-1000 allows you to manage it over the network.

More often than not, you have more than one IES-1000 for a particular installation. Before you start configuring
the IES-1000s, make sure that you

1. Plan ahead.

2. Have a complete diagram showing the whole network.

3. Record the IP parameters assigned to the equipment in your network.

12.1 Setting the IP Address

To set the IP address, default gateway and the subnet mask of the Ethernet port of a network module, use the
following command sequence.

1.

2.

3.

4.

5.

where

Line 1 brings you to the IP subsystem.

Line 2 allows you to add a new IP address for the IES-1000. The IP address of the IES-1000 is displayed in the
command prompt. The system automatically computes the subnet mask when the system is restarted. If you want
to specify a subnet manually, add the following two commands before line 4:

192.168.1.1 ip> subnet delete ether.home

192.168.1.1 ip> subnet add ether.home ether <subnet address> <subnet mask>

where <subnet mask> is the subnet mask in hexadecimal, for example “ff:ff:ff:00”.

192.168.1.1> ip

192.168.1.1 ip> enable ether <new ip address>

<new ip address> ip> route delete default

<new ip address> ip> route add default 0.0.0.0 <default gateway>
00:00:00:00

<new ip address> ip> config save

<new ip address> =

<default gateway> =

The IP address you want to configure for the network module.

The default gateway IP address of the network module.

Line 3 deletes the existing default route.

Line 4 adds the new default route. The default route tells the system where the gateway (next hop) is when the
IES-1000 sends packets to a destination that is not on the same subnet as the IES-1000.

Line 5 saves the new configuration to the nonvolatile memory.

IP Commands 12-1

IES-1000 User’s Guide

For example, if you want the IES-1000 to have 172.21.100.1 as the IP address, 255.255.255.0 for the subnet mask
and 172.21.100.254 for the default gateway, you may use the following command sequence:

192.168.1.1> ip

192.168.1.1 ip> enable ether 172.21.100.1

192.168.1.1 ip> subnet delete ether.home

192.168.1.1 ip> subnet add ether.home ether 172.21.100.0 ff:ff:ff:00

192.168.1.1 ip> route delete default

192.168.1.1 ip> route add default 0.0.0.0 172.21.100.254 00:00:00:00

192.168.1.1 ip> config save

Figure 12-1 Setting IP Address and Default Gateway

The IES-1000 leaves the factory with a default IP address of 192.168.1.1 and a subnet mask of 255.255.255.0, or
FF.FF.FF.0 in hexadecimal notation, and the default gateway set at 192.168.1.254. Make sure that you configure
the IP parameters correctly before you connect an IES-1000 to the network, otherwise, you may interrupt services
already running.

12.2 General IP Commands

Remote

This chapter shows you how to manage the IES-1000 remotely.

More often than not, you will have the IES-1000 located remotely making its remote management features very
useful.

Management

13.1 Management by Telnet

After you have set up the IP parameters and connected the IES-1000 to the network, you can manage it remotely
with telnet. You can use any telnet client that you find convenient. The configuration procedures with telnet are
exactly the same as those using the direct connection via the console port. The default password for a telnet
session is “1234”. Although telnet will work while the console port is being used, only one telnet session is
allowed at a time.

13.2 SNMP Management

SNMP (Simple Network Management Protocol) is a protocol used for exchanging management information
between network devices. The IES-1000 supports SNMP versions one and two (SNMPv1 and SNMPv2) agent
functionality, which allows a manager station to manage and monitor it through the network.

The next figure illustrates an SNMP management operation.

IES-1000 User’s Guide

Figure 13-1 SNMP Management Model

An SNMP managed network consists of two main component types: agents and a manager.

An agent is a management software module that resides in a managed device (the IES-1000). An agent translates
the local management information from the managed device into a form compatible with SNMP. The manager is
the station through which network administrators perform network management functions. It executes operations
that control and monitor the managed devices.

The managed devices contain objects that define each piece of information to be collected about a device.
Examples of variables include the number of packets received, node port status, etc. A Management Information
Base (MIB) is a collection of managed objects. SNMP allows manager and agents to communicate for the purpose
of accessing these objects.

SNMP itself is a simple request/response protocol based on the manager/agent model. The manager issues a
request and the agent returns responses using the following protocol operations:

♦ Get

Allows the manager to retrieve an object variable from the agent.

♦ GetNext

Allows the manager to retrieve the next object variable from a table or list within an agent. In SNMPv1, when a
manager wants to retrieve all elements of a table from an agent, it initiates a Get operation, followed by a series of
GetNext operations.

♦ Set

Allows the manager to set values for object variables within an agent.

IES-1000 User’s Guide

♦ Trap

Used by the agent to inform the manager of some events.

13.2.1 Supported MIBs

The network module supports MIB II that is defined in RFC 1213 and RFC 1215 as well as transparent bridge
MIBs defined in RFC 1493. The network module can also respond with specific data from the ZyXEL private
MIB (ZYXEL-MIB).

13.3 SNMP Access Configuration

To control access to the agent in the network module, use the access commands in the SNMP subsystem. Note

that “community” is SNMP’s terminology for password. After configuring the SNMP access parameters, save the
configuration to the nonvolatile memory with the config save command. The default write community string
is “1234”, and the default read community string is “public”.

13.3.1 SNMP Access Read/Write Command

Syntax:

access <read | write> <community> [<IP addr>]

where

<read | write> =

<community> =

[<IP addr>] =

This command allows read-only or read-write access. If the IP address is specified, access is allowed for the
manager station with that address only.

Specifies read-only/read-write permission.

The password needed to access the SNMP agent on the network module.

The optional IP address of the allowed SNMP manager.

13.3.2 SNMP Access Delete Command

Syntax:

access delete <community> [<IP addr>]

This command revokes SNMP access by the specified community (password). If the IP address is specified,
access is denied for that manager station only.

13.3.3 SNMP Access Flush Command

Syntax:

access flush

Remote Management 13-3

IES-1000 User’s Guide

This command revokes access by any and all manager stations.

13.3.4 SNMP Access List Command

Syntax:

access list

This command shows the allowed access.

13.4 SNMP Trap Configuration

The network module uses the SNMP trapping facility to proactively report unusual events to one or more trap
servers. To configure the trap parameters, use the trap commands in the SNMP subsystem. After configuring the
SNMP trap parameters, save the configuration to the nonvolatile memory with the config save command.

13.4.1 Supported Traps

The network module supports the following traps

♦ coldStart Trap (defined in RFC 1215) :

This trap is sent at system start-up.

♦ authenticationFailure Trap (defined in RFC 1215) :

This trap is sent if a request arrives with an invalid community string.

♦ linkUp Trap (defined in RFC 1215) :

This trap is sent when a DSL port is up.

♦ linkDown Trap (defined in RFC 1215) :

This trap is sent when a DSL port is down.

♦ overheat Trap (defined in ZYXEL-MIB) :

This trap is sent periodically when a network module is overheated.

♦ overheatOver Trap (defined in ZYXEL-MIB) :

This trap is sent when the network module is no longer overheated.

13.4.2 Trap Add Command

Syntax:

trap add <community> <IP addr>

where

<community> =
