The following example shows how to change the advertise interval using the advertise-interval command.
DellEMC(conf-if-te-1/1)#vrrp-group 111
DellEMC(conf-if-te-1/1-vrid-111)#advertise-interval 10
DellEMC(conf-if-te-1/1-vrid-111)#
The following example shows how to verify the advertise interval change using the show conf command.

Track an Interface or Object
You can set Dell EMC Networking OS to monitor the state of any interface according to the virtual group.
Each VRRP group can track up to 12 interfaces and up to 20 additional objects, which may affect the priority of the VRRP
group. If the tracked interface goes down, the VRRP group’s priority decreases by a default value of 10 (also known as cost). If
the tracked interface’s state goes up, the VRRP group’s priority increases by 10.
The lowered priority of the VRRP group may trigger an election. As the Master/Backup VRRP routers are selected based on the
VRRP group’s priority, tracking features ensure that the best VRRP router is the Master for that group. The sum of all the costs
of all the tracked interfaces must be less than the configured priority on the VRRP group. If the VRRP group is configured as
Owner router (priority 255), tracking for that group is disabled, irrespective of the state of the tracked interfaces. The priority
of the owner group always remains at 255.
For a virtual group, you can track the line-protocol state or the routing status of any of the following interfaces with the
interface interface parameter:
● For a 10-Gigabit Ethernet interface, enter the keyword TenGigabitEthernet then the slot/port/subport[/subport]
information.
● For a 40-Gigabit Ethernet interface, enter the keyword fortyGigE then the slot/port information.
● For a port channel interface, enter the keywords port-channel then a number.
● For a VLAN interface, enter the keyword vlan then a number from 1 to 4094.
For a virtual group, you can also track the status of a configured object (the track object-id command) by entering its
object number.
NOTE:
You can configure a tracked object for a VRRP group (using the track object-id command in INTERFACE-
VRID mode) before you actually create the tracked object (using a track object-id command in CONFIGURATION
mode). However, no changes in the VRRP group’s priority occur until the tracked object is defined and determined to be
down.
In addition, if you configure a VRRP group on an interface that belongs to a VRF instance and later configure object tracking on
an interface for the VRRP group, the tracked interface must belong to the VRF instance.
Tracking an Interface
To track an interface, use the following commands.
NOTE: The sum of all the costs for all tracked interfaces must be less than the configured priority of the VRRP group.
● Monitor an interface and, optionally, set a value to be subtracted from the interface’s VRRP group priority.
INTERFACE-VRID mode
track interface [priority-cost cost]
The cost range is from 1 to 254.
