Important Considerations
For resilient links, the main and standby ports are shown in ascending
order.
When you are prompted to select ports, you can enter
matrix of information about the 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 Summary Display
Field Description
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 Whether GARP VLAN Registration Protocol (GARP) is
(Multilayer enabled or disabled on the port. For GVRP to function on
Switching the port, you must enable it on the port as well as the
Modules only) entire bridge. To configure GVRP on a port, see "bridge
port gvrpState" later 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.
portId Port identification, which includes the port priority value
(first 2 digits after "0x") and the logical port number (last
2 digits). Both are shown as hexidecimal values.
portNumber Logical index number that the module assigns to the
bridge port, which may not correspond with the physical
port number depending on your configuration. (For
example, when you define a trunk, only the anchor port
receives a portNumber.) As you add and remove logical
ports, portNumbers are reassigned so that they remain
consecutive.
rxDiscards Total number of frames received on the bridge port that
have been discarded. This value reflects a summary of all
statistics that end with Discs, Discards, or Filters.
