Command History
Usage Guidelines This command applies to HSRP running over FDDI only. Packets are sent every 10 seconds to refresh
the MAC cache on learning bridges or switches. By default, the MAC cache entries age out in
300 seconds (5 minutes).
All other routers participating in HSRP on the FDDI ring receive the refresh packets, although the
packets are intended only for the learning bridge or switch. Use this command to change the interval.
Set the interval to 0 if you want to prevent refresh packets (if you have FDDI but do not have a learning
bridge or switch).
Examples This example shows how to change the MAC-refresh interval to 100 seconds. In this example, a learning
bridge needs to miss three packets before the entry ages out.
ssl-proxy (config-vlan)# standby mac-refresh 100
ssl-proxy (config-vlan)#
seconds Number of seconds in the interval at which a packet is sent to refresh the MAC
cache; valid values are from 1 to 255 seconds.
