Field Description
Trunk Name The user-created name for the trunk.
Type The interface type, which is either Port-Channel (a trunk) or Member Port (a physical port).
Flap Count The number of times the interface has gone down. The counter for a member port is incremented
when the physical port is either manually shut down by the administrator or when its link state is
down. When a trunk is administratively shut down, the flap counter for the trunk is incremented,
but the flap counters for its member ports are not affected. When all active member ports for a
trunk are inactive (either administratively down or link down), then the trunk flap counter is
incremented.
