What happens if a BPDU is received on a port that has BPDU Guard configured?

  • The BPDU is sent to the closest root port.
  • The port is disabled.
  • The BPDU is ignored.
  • The BPDU is returned to the sender.

Explanation: If a BPDU Guard-enabled port receives a BPDU, it triggers a security mechanism that puts the port into an error-disabled state and immediately disables (shuts down) the port.
