Important Considerations

■The port numbering that is displayed for your ports is always sequential, although it depends on the placement of the modules that you have configured into your system. See the Implementation Guide for your system for more information about port numbering.

■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 system. This
	value is useful for determining the relative stability of the
	topology.
gvrpState	Whether the GARP VLAN Registration Protocol (GVRP) is
(3500, 9000 L3)	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 9.
