An administrator issues the command `show spanning-tree interface gigabitethernet 0/1` on a Cisco Catalyst switch connected to a workstation. The command output indicates that the port is in the `FWD` state and lists `P2p Edge` under the Type column. Which operational behavior is directly associated with this interface status?
- The interface immediately transitions to the forwarding state upon linkup by bypassing the listening and learning states.Cevap
- BThe interface automatically filters all incoming Bridge Protocol Data Units (BPDUs) to prevent topology recalculation.
- CThe interface can be safely configured on switch-to-switch trunk links to eliminate spanning-tree convergence timers.
- DThe interface modifies the switch bridge priority by adding an incremental offset of 4096 to prevent root bridge election.
Cevap
The interface immediately transitions to the forwarding state upon linkup by bypassing the listening and learning states.
When an interface is designated as an Edge port (PortFast enabled), it transitions directly to the forwarding state upon link activation. This bypasses the listening and learning states, preventing convergence delays for end-user workstations.
