•Designated Cost – The cost for a packet to travel from this port
to the root in the current Spanning Tree configuration. The
slower the media, the higher the cost.
•Designated Bridge – The priority and MAC address of the
device through which this port must communicate to reach the
root of the Spanning Tree.
•Designated Port – The priority and number of the port on the
designated bridging device through which this switch must
communicate with the root of the Spanning Tree.
•Trunk Member – Indicates if a port is a member of a trunk.
(STA Port Information only)
The following interface attributes can be configured:
•Priority – Defines the priority used for this port in the
Spanning Tree Protocol. If the path cost for all ports on a switch
are 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 Protocol is det ecting network loops.
Where more than one port is assigned the highest priority, the
port with lowest numeric identifier will be enabled.
