VSRP
Advertise-backup Whether the device is enabled to send VSRP Hello messages when it is a Backup.
This field can have one of the following values:
• disabled – The device does not send Hello messages when it is a Backup.
• enabled – The device does send Hello messages when it is a Backup.
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.
save-current The source of VSRP timer values preferred when you save the configuration. This
field can have one of the following values:
• false – The timer values configured on this device are saved.
• true – The timer values most recently received from the Master are saved
instead of the locally configured values.
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 true value is the value listed in the Configured or Current field divided by the scale value.
priority The device 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determining that the Master is no longer active.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: An 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 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 Layer 3 Switch itself will become the Master.
NOTE: This field applies only when this device is a Backup.
Member ports The ports in the VRID.
