Hi !

Thank you very much for you awesome script !

My new Cisco C9200L-48P-4X with version 17.06.03 shows "Critical: 100% of outgoing traffic is broadcast" when polling the port-channel but not on the member-port:

The Port-Channel currently consists of only 1 port at the moment:

Flags:  D - down        P - bundled in port-channel
        I - stand-alone s - suspended

When I poll the member interface directly the output is fine:
