Field Description
rxFrames Total number of frames that this bridge port received
from its segment. However, unlike the rxFrames field in
the Ethernet display which counts all frames, this field
does not count frames in error. Thus, this value may be
lower than the value shown in the rxFrames field in the
Ethernet display.
state Current STP operating state of the port:
stp Configurable status of STP on a port. If bridge-wide STP is
enabled, the port STP configuration options are:
If bridge-wide STP is disabled, the port STP setting has no
effect. To see a matrix of port and bridge STP settings, see
"bridge port stpState" in this chapter.
txFrames Number of frames that this port has transmitted. This
object counts a frame transmitted on the interface that
corresponds to this port only if the frame is for a protocol
that the local bridging function is processing (includes
bridge management frames).
Blocking — The bridge continues to run STP on the
port, but the bridge does not receive packets from the
port, learn locations of station addresses from it, or
forward packets onto it.
Listening — The bridge continues to run STP and
to transmit configuration messages on the port, but it
discards packets that are received on the port and does
not transmit packets that are forwarded to the port.
Learning — STP operating state in which the bridge
receives packets on the port to learn the location of
some of the stations that are located on the port.
Forwarding — The bridge receives packets on the
port and forwards or does not forward them,
depending on address comparisons with the bridge's
source address list. Provided that the link state is up,
this state field indicates forwarding even if STP is
disabled for the bridge.
Disabled — Management has disabled the port or
the link state is down.
enabled — STP sets the operating state of the port
(blocking, listening, etc.) according to network
characteristics. This is the default for all ports.
disabled — STP is disabled and the port is disabled.
The port does not participate in STP decisions, frame
reception, or frame transmission.
removed — STP is disabled on the port but the port
can still receive or transmit frames if its link state is up.
