Description (partial)

Symptom:
Port-channel interface does not seem to set the MTU correctly even though 'show run interface' shows the mtu configured under the port-channel interface. e.g.: jumbo frames may be hardware rate limited even though MTU is configured to allow jumbo frames.

Conditions:
1) If the MTU is configured on the port-channel member interface before creating the port-channel interface, the MTU may not be set correctly on the port-channel interface itself.

2) If the MTU was never configured on the member port, but was configured on the port-channel then the member port MTU does not reflect the port-channel MTU once it is removed from the port-channel.
