Configuring AAA Services on Cisco IOS-XR Software module of the Cisco IOS-XR
System Security Configuration Guide.
This command is ignored when issued on interfaces that do not use ARP. Also,
ARP entries that correspond to the local interface or that are statically
configured by the user never time out.
The show interfaces command displays the ARP timeout value in
hours:minutes:seconds, as follows:
* * * * * * * * * * * * * * * * START OF LISTING * * * * * * * * * * * * * * * *
ARP type: ARPA, ARP Timeout 04:00:00
* * * * * * * * * * * * * * * * END OF LISTING * * * * * * * * * * * * * * * *
EXAMPLES
The following example shows how to set the ARP timeout to 3600 seconds to
allow entries to time out more quickly than the default:
* * * * * * * * * * * * * * * * START OF LISTING * * * * * * * * * * * * * * * *
RP/0/RP0/CPU0:router# configure
RP/0/RP0/CPU0:router(config)# interface MgmtEth 0/RP1/CPU0/0
RP/0/RP0/CPU0:router(config-if)# arp timeout 3600
* * * * * * * * * * * * * * * * END OF LISTING * * * * * * * * * * * * * * * *
