Description
Set the minimum interval to be allowed between back-to-back failovers for the specified redundancy group (affects manual failovers, as well as automatic failovers associated with monitoring failures).
For redundancy group 0, this setting prevents back-to-back failovers from occurring less than 5 minutes (300 seconds) apart. Note that a redundancy group 0 failover implies a Routing Engine failure.
For some configurations, such as ones with a large number of routes or logical interfaces, the default or specified interval for redundancy group 0 might not be sufficient. In such cases, the system automatically extends the dampening time in increments of 60 seconds until the system is ready for failover.
Options
number—Number
of seconds specified for the interval.
Range: For redundancy group 0, 300 through 1800 seconds; for redundancy group 1 through 128, 0 through 1800 seconds.
Default: For redundancy group 0, 300 seconds; for redundancy group 1 through 128, 1 second.
Required Privilege Level
