Interface Configuration (Ethernet, Port Channel)

Command Usage

•You can enable this option if an interface is attached to a LAN segment that is at the end of a 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 STA-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.

Example

Console(config)#interface ethernet 1/5

Console(config-if)#spanning-tree edge-port

Console(config-if)#
