OS10 Enterprise Edition User Guide Release


Forward traffic

EdgePort allows the interface to forward traffic approximately 30 seconds sooner as it skips the Blocking and Learning states. The spanning-tree bpduguard enable command causes the interface hardware to shut down when it receives a BPDU.

  • CAUTION: Configure EdgePort only on links connecting to an end station. EdgePort can cause loops if you enable it on an interface connected to a network.

When you implement BPDU guard, although the interface is placed in Error Disabled state when receiving the BPDU, the physical interface remains in the Up state. The hardware discards regular network traffic after a BPDU violation. BPDUs are forwarded to the CPU, where they are discarded as well.

  • Enable EdgePort on an interface in INTERFACE mode.
