Table 6-36   Bridge-port STP Attributes

Bridge-Port-
Priority

A 1-octet value that allows the network manager to influence the 
choice of port when a bridge has two ports connected in a loop.

 

Bridge-Port-
State

The current state of the port: Disabled, Listening, Learning, 
Forwarding, or Blocking. 

Bridge-Port-
Path-Cost

The cost to be added to the root-path-cost field to determine the 
cost of the path to the root through this port.

Bridge-Port-
Designated-
Root

ID of the bridge in the root-identifier parameter transmitted by 
the designated-Bridge for the LAN to which the port is attached.

Bridge-Port-
Designated-
Cost

Cost of the path to the root-bridge offered by the 
designated-port on the LAN to which this port is attached.

Bridge-Port-
Designated-
Bridge

ID of the bridge assumed to be the designated-bridge for the 
LAN associated with the port. The parameter is used: (a) together 
with the designated-port and port-identifier parameters for the 
port to ascertain whether this port should be the designated-port 
for the LAN to which it is attached; (b) to test the value of the 
bridge Identifier parameter conveyed in received CBPDUs.

Bridge-Port-
Designated-
Port

The port-identifier of the bridge-port assumed to be the 
designated-port for the LAN associated with the port. The 
parameter is used: (a) together with the designated-bridge and 
port-identifier parameters for the Port to ascertain whether this 
Port should be the designated-port for the LAN to which it is 
attached; (b) by management to determine the topology of the 
bridged Local Area Network..
