Interface Configuration (Ethernet, Port Channel)

• 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.

This command sets an interface to fast forwarding. Use the no form to 
disable fast forwarding.
