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 rep lsl-age-timer interface configuration
command on a Resilient Ethernet Protocol (REP) port. Use the no form of this command to return to the
default time.

Command Modes Interface configuration
Command History
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.
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 gigabitethernet0/2
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.
