Description
A redundant secondary master controller in a branch controller deployment prevents a scenario in which a
master controller acts as a single point of failure if the link to the master controller goes down, or a co-located
Master-Standby VRRP controller pair fail due to a network failure or local natural disaster.
This command displays the status of both the primary and secondary (backup) master controllers. It also
shows the currently configured switchover-timeout value.
Syntax
Parameter Description
status
Displays the IP address and status of the Layer-3 master controller and the
secondary (backup)master controller.
switchover-timeout
This switchover period defines the number of minutes that a primary branch
master controller will wait before switching from an unreachable primary
controller to the backup controller.
l Switchover-timeout range: 15 - 60 minutes
l Default: 15 minutes
Usage Guidelines
You can run this command only from a branch controller.
Issue this command to:
l View the status of the primary and backup master controllers.
l View the current setting for the number of minutes configured to wait before the switchover is made from
the primary master controller to the backup Layer-3 master controller.
If there is no secondary master controller configured for the primary branch controller, the Master L3-
Redundancy feature is not enabled. In this case, the CLI displays the following message:
L3-domain master redundancy not configured.
