Command Usage
• You can enable this option if an interface is attached to a LAN segment
that is at the end of bridged LAN or to an end node. Since end nodes
cannot cause forwarding loops, they can pass directly through to the
Spanning Tree forwarding state. Specifying Edge Ports provides
quicker convergence for devices such as workstations or servers,
retains the current forwarding database to reduce the amount of frame
flooding required to rebuild address tables during reconfiguration
events, does not cause the Spanning Tree to initiate reconfiguration
when the interface changes state, and also overcomes other
STP-related timeout problems. However, remember that Edge Port
should only be enabled for ports connected to an end-node device.
• This command has the same effect as the spanning-tree portfast
command.
Example
Console(config)#interface ethernet 1/5
Console(config-if)#spanning-tree edge-port
