Chapter 2 Cisco IOS Commands for the Catalyst 4500 Series Switches
rep lsl-age-timer
rep lsl-age-ti mer
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 RE P neighbor. Use the no form of this command to return to the
default time.
rep lsl-age timer valu e
no rep lsl-age timer
Syntax Description
Defaults The REP link shuts down if it does not receive a hello message from a neighbor within 5000 ms.
Command Modes Interface configuration
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 in crements. If the REP neig hbor device is not running Cisc o
IOS Release 12.2(52)SE o r late r, you must use the short er 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 po rt channel , you recei ve an error m essage and the com mand
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 privilege d EXEC
command .

value The age-out time in milliseconds. The range is from 120 to 10000 ms in 4 0-ms
increments. The default is 5000 ms (5 seconds).
