Configuring LAN Interfaces

Configuring a LAN Extender Interface

IC-54

Cisco IOS Interface Configuration Guide

To control priority queueing on a LAN Extender interface, perform the following tasks:

• Set the priority by protocol type.

• Assign a priority group to an interface.

To establish queueing priorities based on the protocol type, use one of the following commands in global

configuration mode:

You then assign a priority list to an interface. You can assign only one list per interface. To assign a

priority list to a LAN Extender interface, use the following command in interface configuration mode:

Controlling the Sending of Commands to the LAN Extender

Each time the core router sends a command to the LAN Extender, the LAN Extender responds with an

acknowledgment. The core router waits for the acknowledgment for a predetermined amount of time. If

it does not receive an acknowledgment in this time period, the core router sends the command again.

By default, the core router waits 2 seconds for an acknowledgment from the LAN Extender. You might

want to change this interval if your connection to the LAN Extender requires a different amount time.

To determine whether commands to the LAN Extender are timing out, use the debug lex rcmd privileged

EXEC command. To change this interval, use the following command in interface configuration mode:

By default, the core router sends each command ten times before giving up. The core router displays an

error message when it gives up sending commands to the LAN Extender. To change this default, use the

following command in interface configuration mode:

Command Purpose

priority-list list protocol protocol

{high | medium | normal | low}

priority-list list protocol bridge {high

| medium | normal | low} list list-number

Establishes queueing priorities based on the protocol type.

Command Purpose

lex priority-group group

Assigns a priority list to a LAN Extender interface, which activates priority

output queueing on the LAN Extender.

Command Purpose

lex timeout milliseconds

Sets the amount of time that the core router waits to receive an acknowledgment

from the LAN Extender.

Command Purpose

lex retry-count number

Sets the number of times the core router sends a command to the LAN Extender

before giving up.
