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 STA-
related timeout problems. However, remember that Edge Port should only be
enabled for ports connected to an end-node device.
