Figure 4. Object tracking
Interface tracking
You can create an object that tracks the line-protocol state of an L2 interface, and monitors its operational up or down status. You can
congure up to 500 objects. Each object is assigned a unique ID.
When the link-level status goes down, the tracked resource status is also considered Down. If the link-level status goes up, the tracked
resource status is also considered Up. For logical interfaces such as port-channels or VLANs, the link-protocol status is considered Up if any
physical interface under the logical interface is Up.
The list of available interfaces include:
• ethernet — Physical interface
• port-channel — Port-channel identier
• VLAN — Virtual local area network (VLAN) identifer
• Loopback — Loopback interface identier
