stack switch-over
With FastIron release 08.0.20, the
stack switch-over
command is allowed by default. In earlier releases, hitless failover must first be
enabled.
Global configuration mode on a stack controller
Use the
stack switch-over command before reloading or performing maintenance on the currently active controller.
Hitless failover must be enabled for the command to be used; otherwise, an error message
is issued.
The command cannot be used during stack election or during configuration of a multi-stack-trunk.
A standby controller must exist and must have learned stack protocols for the command to be used. The standby controller must have the same priority as the active controller for the command to be used.
More than 120 seconds must have passed since the previous switchover or failover for the command to be accepted.
The following example shows the
stack switch-over command being entered and the resulting output. You must confirm the switch-over
before it can take effect by entering
y when prompted.
device# stack switch-over Standby unit 8 will become active controller, and unit 1 will become standby Are you sure? (enter 'y' or 'n'): y Unit 1 is no longer the active controller
