• 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.
