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.
portNumber Logical index number that the system assigns to the
bridge port, which may not correspond with the physical
port number depending on your system 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.
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.
priority Configurable STP port priority value. The default value is
0x80. (0x signifies that the value to follow is a
hexadecimal number.) The acceptable range is 0x0 – 0xff.
To configure port priority values, see “bridge port
stpPriority” in this chapter.
The port priority is included in the port ID and is
considered the most significant portion because it is the
first factor that determines if a port is to be the
designated port when more than one bridge port is
attached to the same LAN. The lowest priority is chosen. If
all ports in a bridge have the same priority, then the port
number is used as the determining factor.
rxAllFilters
(3500 and 9000 L3) Number of frames that the bridge port discarded due to a
user-defined packet filter on its “receive all” path.
rxBlockedDiscs
(3500 and 9000 L3) Number of frames that the bridge port discarded because
the receiving bridge port was not in the forwarding state.
rxErrorDiscs Number of frames that the bridge port discarded because
of internal bridge system errors (such as hardware and
software address table discrepancies).
rxForwards
(3500 and 9000 L3) Total number of frames (all types) that the bridge port
received and forwarded to another bridge port.
rxForwardMcasts
(3900, 9300, 9400, and
9000 L2) Number of multicast frames that the bridge port received
and forwarded to another bridge port.
rxForwardUcasts
(3900, 9300, 9400, and
9000 L2) Number of unicast frames the bridge port received and
forwarded to another bridge port.
rxFloodUcasts Number of unicast frames that the port received and
flooded to one or more ports.
