Monitor Port-Channels
To check the status of a Layer 2 port-channel, use f10LinkAggMib (.1.3.6.1.4.1.6027.3.2). In the following
example, Po 1 is a switchport and Po 2 is in Layer 3 mode.

Example of Viewing Status of Learned MAC Addresses
If we learn MAC addresses for the LAG, status is shown for those as well.

Example of Viewing Changed Interface State for Monitored Ports
Layer 3 LAG does not include this support. SNMP trap works for the Layer 2 / Layer 3 / default mode LAG.
