Important Considerations
■
For resilient links, the main and standby ports are shown in ascending
order.
■
When you are prompted to select ports, specify the
?
option to see a
list of information about your bridge ports. This matrix is useful, for
example, if you have trunks configured but forget which port is the
anchor port. You must use the anchor port number to display a port
summary for a trunk.
Fields in the Bridge Port Detail Display
Field
Description
designatedBridge
Identity of the designated bridge of the LAN to which the
port is attached. It is an STP port parameter.
designatedCost
Cost through this port to get to the root bridge. The
designated cost of the root port is the same as the cost
that is received in incoming BPDUs from the designated
bridge for that LAN. It is an STP port parameter.
designatedPort
Identity of the designated port on the designated bridge.
designatedRoot
Identity of the root bridge in the LAN, which includes the
root bridge’s priority value and the MAC address of port 1
on that bridge.
fwdTransitions
Number of times that the port has entered the forwarding
state since you enabled STP or rebooted the module. This
value is useful for determining the relative stability of the
topology.
gvrpState
(Multilayer Switching
Modules only)
Whether the GARP VLAN Registration Protocol (GVRP) is
enabled or disabled on the port. For GVRP to function on
the port, you must enable it on the port as well as the
entire bridge. To configure GVRP on a port, see “bridge
port gvrpState” in this chapter. To configure GVRP on the
bridge, see “bridge gvrpState” in Chapter 6.
linkState
State of the link
(
up
or
down
), that is, whether it is
available for communication.
pathCost
Cost to add to the total path cost when this port is the
root port. To configure a port’s STP cost, see “bridge port
stpCost” in this chapter.
