Object Tracking Configuration; Tracking A Layer 2 Interface - Dell Force10 C150 Configuration Manual

You can assign a unique priority-cost value from 1 to 254 to each tracked VRRP object or group interface.
The priority cost is subtracted from the VRRP group priority if a tracked VRRP object is in a DOWN state.
If a VRRP group router acts as owner-master, the run-time VRRP group priority remains fixed at 255 and
changes in the state of a tracked object have no effect. For more information on how to track a VRRP
object, see Track an Interface or Object on page
Note: In VRRP object tracking, the sum of the priority costs for all tracked objects and interfaces cannot
equal or exceed the priority of the VRRP group.

Object Tracking Configuration

You can configure the following types of object tracking for a client:
• Tracking a Layer 2 Interface on page 681
• Tracking a Layer 3 Interface on page 682
• Tracking an IPv4/IPv6 Route on page 684
For a complete listing of all commands related to object tracking, refer to the

Tracking a Layer 2 Interface

You can create an object that tracks the line-protocol state of a Layer 2 interface and monitors its
operational status (UP or DOWN). You can track the status of any of the following Layer 2 interfaces:
• 1-Gigabit Ethernet: Enter
below).
• 10-Gigabit Ethernet: Enter
• Port channel: Enter
• For the C-Series and S-Series, 1 to 128
• For the E-Series, 1 to 32 (EtherScale) and 1 to 255 (TeraScale and ExaScale)
• SONET: Enter
• VLAN: Enter
A line-protocol object only tracks the link-level (UP/DOWN) status of a specified interface. When the
link-level status goes down, the tracked object status is considered to be DOWN; if the link-level status is
up, the tracked object status is considered to be UP.
