What is the effect of entering the shutdown configuration command on a switch?

  • It disables an unused port.
  • It enables portfast on a specific switch interface.
  • It disables DTP on a non-trunking interface.
  • It enables BPDU guard on a specific port.
Explanation & Hint:

Entering the shutdown configuration command on a switch interface has the effect of disabling that specific interface. This command administratively turns off the port, making it inactive and unable to send or receive traffic. This is commonly used to disable unused ports for security purposes or to perform maintenance on a network.

  • It disables an unused port. This is the correct effect of the shutdown command. The port is administratively disabled and will not function until it is re-enabled with the no shutdown command.

The other options listed are not the effects of the shutdown command:

  • It enables portfast on a specific switch interface. This is incorrect. PortFast is a feature that can be enabled on switch ports connected to end devices to bring the port to the forwarding state rapidly. It is enabled with a different command (spanning-tree portfast).
  • It disables DTP on a non-trunking interface. This is also incorrect. The shutdown command does not specifically relate to DTP. Disabling DTP on a switch port requires a different set of commands (switchport nonegotiate or setting the port to a static access or trunk mode).
  • It enables BPDU guard on a specific port. This is incorrect. BPDU guard is a feature used in conjunction with STP PortFast to prevent potential network loops by disabling a port that receives a BPDU. It is enabled with a different command (spanning-tree bpduguard enable).
