ports attached to faster media, and higher values assigned to ports with
slower media. (Path cost takes precedence over port priority.) Note
that when the Path Cost Method is set to short (page 3-63), the
maximum path cost is 65,535.

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. (This is the
default setting.)
•
Admin Edge Port
(Fast Forwarding) – 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. (Default: Disabled)
