Do not create a standby
group before executing
this command.
 Note:
z You may configure different authentication modes and authentication keys for the
standby groups on an interface. However, the members of the same standby group
must use the same authentication mode and authentication key.
z Factors like excessive traffic or different timer setting on switches can cause the
Backup timer to time-out abnormally and trigger a change of the state. To solve this
problem, you can prolong the time interval to send VRRP packets and configure a
preemption delay.
