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
.
