Preempt-mode Whether the device can be pre-empted by a device with a higher VSRP priority
after this device becomes the Master. This field can have one of the following
values:
•
disabled – The device cannot be pre-empted.
•
enabled – The device can be pre-empted.
NOTE: For the following fields:
•
Configured – indicates the parameter value configured on this device.
•
Current – indicates the parameter value received from the Master.
•
Unit – indicates the formula used tor calculating the VSRP priority and the timer scales in effect for the
VSRP timers. A timer’s true value is the value listed in the Configured or Current field divided by the
scale value.
priority The device’s preferability for becoming the Master for the VRID. During
negotiation, the Backup with the highest priority becomes the Master.
If two or more Backups are tied with the highest priority, the Backup interface
with the highest IP address becomes the Master for the VRID.
hello-interval The number of seconds between Hello messages from the Master to the
Backups for a given VRID.
dead-interval The configured value for the dead interval. The dead interval is 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before determining that the Master is no longer active.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.
NOTE: If the value is 0, then you have not configured this parameter.
hold-interval The number of seconds a Backup that intends to become the Master will wait
before actually beginning to forward Layer 2 traffic for the VRID.
If the Backup receives a Hello message with a higher priority than its own
before the hold-down interval expires, the Backup remains in the Backup state
and does not become the new Master.
initial-ttl The number of hops a Hello message can traverse after leaving the device
before the Hello message is dropped.
NOTE: A Foundry MRP ring counts as one hop, regardless of the number of
nodes in the ring.
next hello sent in The amount of time until the Master’s dead interval expires. If the Backup does
not receive a Hello message from the Master by the time the interval expires,
either the IP address listed for the Master will change to the IP address of the
new Master, or this device itself will become the Master.
NOTE: This field applies only when this device is a Backup.
master router The IP address of the master router.
Member ports The ports in the VRID.
Operational ports The member ports that are currently up.
Forwarding ports The member ports that are currently in the Forwarding state. Ports that are
forwarding on the Master are listed. Ports on the Standby, which are in the
Blocking state, are not listed.
