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
