Configure an EdgePort

The EdgePort feature enables interfaces to begin forwarding traffic approximately 30 seconds sooner. In
this mode an interface forwards frames by default until it receives a BPDU that indicates that it should
behave otherwise; it does not go through the Learning and Listening states. The

When only
receiving the BPDU, the physical interface remains up and spanning-tree will drop packets in the hardware
after a BPDU violation. BPDUs are dropped in the software after receiving the BPDU violation. This
feature is the same as PortFast mode in Spanning Tree.
Caution:
Configure EdgePort only on links connecting to an end station. EdgePort can cause loops if it is enabled
on an interface connected to a network.
To enable EdgePort on an interface, use the following command:
