Port Path Cost Ð The portion of the total path cost that is associated with
this port. In a parallel bridge network, the Spanning Tree algorithm selects
the bridge with the lowest path cost as the root bridge. The allowable range
for the path cost is 1 to 65535. The default value is 20.
Port State Ð The state of this station port. Table 3-3 provides possible port
states and deÞnitions.
Designated Root Ð The bridge identiÞer, recorded as the root in the
ConÞguration BPDUs transmitted by the Designated Bridge (for the segment
to which this port is attached.) This value is used as the Root IdentiÞer
parameter in all Bridge ConÞguration PDUs originated by this node.
Designated Cost Ð The path cost of the Designated Port of the segment
connected to this port.
Designated Bridge Ð The ID of the bridge that is assumed to be the root
bridge on the network.
Designated Port Ð The number of the port that offers the lowest path from
the TRBMIM to the root bridge.
