• Designated root – The priority and MAC address of the device in the
Spanning Tree that this switch has accepted as the root device.
• Fast forwarding – This field provides the same information as Admin
Edge port, and is only included for backward compatibility with earlier
products.
• Admin Edge Port – 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 reconfigure 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.
• Admin Link Type – The link type attached to this interface.
- Point-to-Point – A connection to exactly one other bridge.
- Shared – A connection to two or more bridges.
- Auto – The switch automatically determines if the interface is
attached to a point-to-point link or to shared media.
