Displaying VRRP and VRRP-E information

current priority

The current VRRP, VRRP v3, VRRP-E, or IPv6 VRRP-E priority of this Layer 3
switch for the VRID. The current priority can differ from the configured priority
(refer to the priority field) for the following reason:
The current priority can differ from the configured priority in the VRID if the
VRID is configured with track ports and the link on a tracked interface has
gone down. Refer to

“Track ports and track priority”

on page 416.

hello-interval

The configured value for the Hello interval. This is the amount of time, in
milliseconds, between Hello messages from the Master to the Backups for a
given VRID.
NOTE: In some VRRP command outputs, Hello interval timers are displayed in

seconds instead of milliseconds.

dead interval

The configured value for the dead interval. This is the amount of time, in
milliseconds, that a Backup waits for a Hello message from the Master for the
VRID before determining that the Master is no longer active.
If the Master does not send a Hello message before the dead interval expires,
the Backups negotiate (compare priorities) to select a new Master for the VRID.
NOTE: If the value is 0, then you have not configured this parameter.
NOTE: This field does not apply to VRRP Owners.
NOTE: All timer fields (Hello interval, dead interval, current dead interval, and

so on) are displayed in milliseconds.

current dead interval

The current value of the dead interval. This value is equal to the value
configured for the dead interval.
If the value for the dead interval is not configured, then the current dead
interval is equal to three times the Hello interval plus Skew time (where Skew
time is equal to 256 minus priority divided by 256).
NOTE: This field does not apply to VRRP Owners.

preempt mode

Whether the backup preempt mode is enabled.
NOTE: This field does not apply to VRRP Owners.

virtual ip address

The virtual IP addresses that this VRID is backing up. The address can be an
IPv4 or IPv6 address.

virtual mac address

The virtual MAC addresses for the VRID. The MAC address can be an IPv4 or
IPv6 address.

advertise backup

The IP addresses of Backups that have advertised themselves to this Layer 3
switch by sending Hello messages.
NOTE: Hello messages from Backups are disabled by default. You must

enable the Hello messages on the Backup for the Backup to advertise
itself to the current Master. Refer to

“Hello messages”

on page 415.

backup router ip-addr expires in
time

The IP addresses of Backups that have advertised themselves to this Master
by sending Hello messages.
The time value indicates how long before the Backup expires. A Backup
expires if you disable the advertise backup option on the Backup or the
Backup becomes unavailable. Otherwise, the Backup next Hello message
arrives before the Backup expires. The Hello message resets the expiration
timer.
An expired Backup does not necessarily affect the Master. However, if you
have not disabled the advertise backup option on the Backup, then the
expiration may indicate a problem with the Backup.
NOTE: This field applies only when Hello messages are enabled on the

Backups (using the advertise backup option).
