Release Information
Statement introduced in Junos OS Release 9.2 for EX Series switches.
Statement introduced in Junos OS Release 11.1 for the QFX Series.
Description
Instruct the backup router to take mastership if it detects a loss of keepalive signal from the master Routing Engine.
Default
The on-loss-of-keepalives statement must be included at the [edit chassis redundancy failover] hierarchy level for failover to occur.
When the on-loss-of-keepalives statement is included but 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.
