Important Considerations
■
The port numbering that is displayed 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, you can enter
?
to see a
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 system. This
value is useful for determining the relative stability of the
topology.
gvrpState
(3500, 9000 L3) Whether GARP VLAN Registration Protocol (GARP) 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” later in this chapter. To configure GVRP
on the bridge, see “bridge gvrpState” in Chapter 9.
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.
