A network administrator uses the spanning-tree portfast bpduguard default global configuration command to enable BPDU guard on switch. However, BPDU guard is not activated on all access ports. What is the couse of the issue?

  • BPDU guard needs to be activated on the interface configuration command mode.
  • PortFast is not configured on all access ports.
  • Access ports configured with root guard cannot be configured with BPDU GURAD.
  • Access ports belong to different VLANs.

Explanation: BPDU guard can be enabled globally on all PortFast-enabled ports by using the spanning-tree portfast bpduguard default global configuration command. If PortFast is not configured, then BPDU guard is not activated.
