Ethernet administrative operational mode

When issuing the show interfaces gigabitethernet 0/0 switchport command, the output shows administrative and operational modes like so:

  • Administrative Mode indicates what we actually configure on that particular port. For example, trunk or access or LAGP or PAgP or ON etc…
  • Operational Mode is the mode with which the port behaves in response to the configuration done onto a particular port, and its negotiation (if any) with the port on the other side of the link.
