Virtual Router table
Port The interface number. All the device’s interfaces are listed.
ID The VRID configured on this interface. If multiple VRIDs are
configured on the interface, information for each VRID is listed
separately.
Hello Intv The number of seconds between Hello messages from the Master to
the Backups for a given VRID.
Activate Indicates whether this VRID is activated. After configuring the VRID,
you must activate it. The VRID is disabled by default.
IP List The IP addresses that this VRID is backing up.
Mode Indicates whether the Layer 3 Switch is the Owner or a Backup for the
VRID.
Note: The mode applies only to VRRP. All Layer 3 Switches
configured for VRRPE are Backups.
Backup – Priority The device’s preferability for becoming the Master for the VRID.
During negotiation, the router with the highest priority becomes the
Master.
If two or more devices are tied with the highest priority, the Backup
interface with the highest IP address becomes the active router for the
VRID.
Backup – Dead Intv The number of seconds 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Master for the VRID before determining that the Master is no longer
active.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.
Backup – Preempt The state of the Backup preempt mode. The Backup preempt mode
prevents a Backup with a higher VRRP priority from taking control of
the VRID from another Backup that has a lower priority but has
already assumed control of the VRID.
Track – Priority A VRRP priority value assigned to the tracked port(s). If a tracked
port’s link goes down, the VRID port’s priority is reduced by the
amount of the tracked port’s priority.
Track – Vif List The virtual interfaces that the VRID’s interface is tracking. If the link
for a tracked interface goes down, the VRRP priority of the VRID
interface is changed, causing the devices to renegotiate for Master.
Track – Port List The physical ports that the VRID’s interface is tracking. If the link for a
tracked port goes down, the VRRP priority of the VRID interface is
changed, causing the devices to renegotiate for Master.
