track c e s Monitor an interface or a configured object and, optionally, reconfigure the cost value subtracted from the VRRP group priority if the tracked interface or object goes down. You can assign up to 12 tracked interfaces and up to 20 tracked objects per virtual group. Syntax track {interface | object-id} [priority-cost cost] Parameters interface object-id cost Enter one of the following values: • For a 1-Gigabit Ethernet interface, enter gigabitethernet slot-number/ port-number. • For a Loopback interface, enter loopback number, where valid loopback interface numbers are from 0 to 16383. • For a Port Channel interface, enter port-channel number, where valid port-channel numbers are: C-Series and S-Series: 1 to 128 E-Series: 1 to 32 for EtherScale; 1 to 255 for TeraScale; 1 to 512 for ExaScale. • For SONET interfaces, enter sonet slot-number/port-number. • For a 10-Gigabit Ethernet interface, enter tengigabitethernet slot-number/ port-number • For a VLAN interface, enter vlan id-number, where valid VLAN IDs are from 1 to 4094. Enter the ID number of an object (for example, IPv4/IPv6 route or Layer 2/Layer 3 interface) configured with one of the track object-id commands. Range: 1 to 65535. (OPTIONAL) Enter a number as the cost amount to be subtracted from the VRRP priority value. Range: 1 to 254. Default: 10. Defaults cost = 10 Command Modes VRRP Command History Version 8.4.1.0 Version 8.3.2.0 Version 7.6.1.0 Version 7.5.1.0 pre-Version 6.2.1.1 Support for the object-id variable was added. Introduced for IPv6 on E-Series TeraScale Introduced on S-Series Introduced on C-Series Introduced on E-Series Usage The sum of the costs of all tracked interfaces and objects cannot equal or exceed the priority of the Information VRRP group. If the VRRP group is configured as the Owner router (priority 255), tracking for the group is disabled, irrespective of the state of tracked interfaces and objects. The priority of the owner group always remains as 255 and does not change. If the specified interface or object goes down or is disabled, the cost value is subtracted from the priority value. As a result, a new MASTER election may occur if the resulting priority value is lower than the priority value in the BACKUP virtual routers. Virtual Router Redundancy Protocol (VRRP) | 1485
