Release Information
Statement introduced before Junos OS Release 7.4.
Description
Configure the time period that must elapse before the backup router takes mastership when it detects loss of the keepalive signal.
Default
The on-loss-of-keepalives statement at the [edit chassis redundancy failover] hierarchy level must be included for failover to occur.
When the on-loss-of-keepalives statement is included and graceful Routing Engine switchover is not configured, failover occurs after 300 seconds (5 minutes).
When the on-loss-of-keepalives statement is included and graceful Routing Engine switchover is configured, the keepalive signal is automatically enabled and the failover time is set to 2 seconds (4 seconds on M20 routers). You cannot manually reset the keepalive time.
Options
seconds—Time before the backup router takes mastership when it detects loss of the keepalive signal. The range of values is 2 through 10,000.
Required Privilege Level
interface—To view this statement in the configuration.
interface-control—To add this statement to the configuration.
