Table 151 Virtual Router Group Priority Tracking Configuration commands
Command

[no] group track ports
show ip vrrp group track
NOTE: If Virtual Router Group Tracking is enabled, then the tracking option will be available only under

Description
Defines the election priority bias for this virtual router group. This can be any
integer between 1 and 254. The default value is 100.
During the master router election process, the routing device with the highest
virtual router priority number wins. If there is a tie, the device with the highest
IP interface address wins. If this virtual router's IP address is the same as the
one used by the IP interface, the priority for this virtual router will automatically
be set to 255 (highest).
When priority tracking is used, this base priority value can be modified
according to a number of performance and operational criteria.
Command mode: Router VRRP
Defines the time interval between VRRP master advertisements. This can be
any integer between 1 and 255 seconds. The default is 1.
Command mode: Router VRRP
Enables or disables master preemption. When enabled, if the virtual router
group is in backup mode but has a higher priority than the current master, this
virtual router will preempt the lower priority master and assume control. Note
preemption
that even when
preempt any other master if this switch is the owner (the IP interface address
address
and virtual router
are the same). By default, this option is enabled.
Command mode: Router VRRP

Command mode: Router VRRP
Disables the virtual router group. This is the default.
Command mode: Router VRRP
Deletes the virtual router group from the switch configuration.
Command mode: Router VRRP
Displays the current configuration information for the virtual router group.
Command mode: All except User EXEC
Description
When enabled, the priority for this virtual router will be increased for each
other IP interface active on this switch. An IP interface is considered active
when there is at least one active port on the same VLAN. This helps elect the
virtual routers with the most available routes as the master. This command is
disabled by default.
Command mode: Router VRRP
When enabled, the priority for this virtual router will be increased for each
active port on the same VLAN. A port is considered ―active‖ if it has a link and
is forwarding traffic. This helps elect the virtual routers with the most available
ports as the master. This command is disabled by default.
Command mode: Router VRRP
Displays the current configuration for priority tracking for this virtual router.
