These additional parameters are only displayed for the CLI:
•Admin status – Shows if STA has been enabled on this
interface.
•Path Cost – This parameter is used by the STA to determine
the best path between devices. Therefore, lower values should
be assigned to ports attached to faster media, and higher values
assigned to ports with slower media. (Path cost takes
precedence over port priority.)
•Priority – Defines the priority used for this port in the
Spanning Tree Algorithm. If the path cost for all ports on a
switch is the same, the port with the highest priority (i.e.,
lowest value) will be configured as an active link in the
Spanning Tree. This makes a port with higher priority less likely
to be blocked if the Spanning Tree Algorithm is detecting
network loops. Where more than one port is assigned the
highest priority, the port with the lowest numeric identifier will
be enabled.
•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 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.
