Rep Lsl-Age-Timer - Cisco Catalyst 4500 Series Command Reference Manual

Chapter 2 Cisco IOS Commands for the Catalyst 4500 Series Switches

rep lsl-age-timer

Use the rep lsl-age-timer interface configuration command on a Resilient Ethernet Protocol (REP) port
to configure the Link Status Layer (LSL) age timer for the time period that the REP interface remains
up without receiving a hello from the REP neighbor. Use the no form of this command to return to the
default time.
Syntax Description value
Defaults
The REP link shuts down if it does not receive a hello message from a neighbor within 5000 ms.
Command Modes
Interface configuration
Command History Release
12.2(44)SG
Usage Guidelines
The LSL hello timer is set to the age-timer value divided by 3 so that there should be at least two LSL
hellos sent during the LSL age-timer period. If no hellos are received within that time, the REP link shuts
down.
In Cisco IOS Release 12.2(52)SE, the LSL age-timer range changed from 3000 to 10000 ms in 500-ms
increments to 120 to 10000 ms in 40-ms increments. If the REP neighbor device is not running Cisco
IOS Release 12.2(52)SE or later, you must use the shorter time range because the device does not accept
values out of the earlier range.
EtherChannel port channel interfaces do not support LSL age-timer values less than 1000 ms. If you try
to configure a value less than 1000 ms on a port channel, you receive an error message and the command
is rejected.
Examples
This example shows how to configure the REP LSL age timer on a REP link to 7000 ms:
Switch(config)# interface GigabitEthernet1/1
Switch(config-if)# rep lsl-age-timer 7000
Switch(config-if)# exit
You can verify the configured ageout time by entering the show interfaces rep detail privileged EXEC
command.
