Response messages
Table 12-8: List of response messages for the swap vrrp(IPv4) command
Notes
•
If this command is executed from a virtual router that has lower or equal priority (including
the default priority), the device status might not be changed to the master status.
•
This command cannot be entered for an address owner's virtual router, a follower virtual
router, or a virtual router in the initial status.
•
If a switch-back command is executed while switch-back is suppressed, the command is given
priority and switch-back is performed.
•
If the command is executed when switch-back is not suppressed, switch-back is performed,
even though that does not seem to be the case because the status of the virtual router with the
higher priority is changed to the master status by the automatic switch-back functionality.
•
When the command is executed, both virtual routers are swapped to the backup or master
status temporarily, but they are changed back to the master or backup status automatically.
•
When switch-back cannot be performed due to a failure of other devices, if the command is
executed, communication is suspended for 4 seconds by default.
•
In a configuration where the
no vrrp preempt
and the
vrrp timers non-preempt-swap
configuration commands are set for all devices that make up the VRRP, if a switch-back
command is executed in the master device, all devices change to the backup status until the
period set for the
vrrp timers non-preempt-swap
command elapses. To avoid this situation,
do not set the
vrrp timers non-preempt-swap
command for at least one of the devices that
makes up the VRRP. If all the devices are in the backup status, you can make one of the
devices the master device by executing the
swap vrrp
command and specifying the device.
The table below lists the results of executing this command. No status change in the following table
indicates situation where it does not seem that switch-back is performed.
