This example shows how to verify if GigabitEthernet 5/8 (configured as a network port), is in a normal
state. (From the show spanning-tree summary output above, we know that Bridge Assurance is enabled
on GigabitEthernet 5/8).

This example shows how port GigabitEthernet 5/8 (configured as a network port), is currently in the
Bridge Assurance inconsistent state:
Note The output shows the port type as network and *BA_Inc, indicating that the port is in an
inconsistent state.
