Parameter
enable-delay: Failover delay, or the delay for the interface to switch its state from main
to standby. It is in the range 0 to 65535 seconds.
disable-delay: Fallback delay, or the delay for the interface to switch from backup to
main. It is in the range 0 to 65535 seconds. It defaults to 0, meaning switching without
delay.
Description
Use the standby timer delay command to set failover and fallback delays on the
interface, avoiding frequent switchover caused by instability of interface state.
Use the undo standby timer delay command to restore the default or 0, meaning
switching without delay.
Before you can use this command, you must use the standby interface command to
specify physical interfaces or logical channels to back up the interface.
Example
# Configure interface Serial 0/0/0 to use interface Serial 1/0/0 for backup, and to
experience 10 seconds of delay before failover or fallback.
[3Com -Serial0/0/0] standby interface serial1/0/0
