Spanning Tree Edge Port Configuration
You can enable some STA options when an interface is attached to a LAN segment
that is at the end of a bridged LAN or is attached to an end node.
Command Attributes
The following interface attributes can be configured:
• Admin Edge Port (Fast Forwarding) – 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. (Default: Enabled)
- Enabled – Manually configures a port as an Edge Port.
- Disabled – Disables the Edge Port setting.
- Auto – The port will be automatically configured as an edge port if the edge
delay time expires without receiving any RSTP or MSTP BPDUs. Note that edge
delay time (802.1D-2004 17.20.4) equals the protocol migration time if a port's
