Table 13-1 Bridge Port Attributes (continued)
Parameter Description
state Spanning Tree state (blocking, listening, learning, forwarding,
disabled) in which the port is currently operating:
Blocking: the bridge continues to run Spanning Tree on that port,
but the bridge does not receive data packets from the port, learn
locations of station addresses from it, or forward packets onto it.
Listening: the bridge continues running the Spanning Tree
algorithm and transmitting configuration messages on the port,
but it discards data packets received on that port and does not
transmit data packets forwarded to that port.
Learning: similar to listening, but the bridge receives data packets
on that port to learn the location of some of the stations located
on that port.
Forwarding: the bridge receives packets on that port and forwards
or does not forward them depending on address comparisons
with the bridge's source address list.
Disabled: the port has been disabled by management.
stp Whether or not the port is enabled or disabled for Spanning Tree.
txAllFilters Number of frames discarded because of a user-defined packet
filter on the transmit all path of this bridge port
txBlockedDiscs Number of frames discarded by this port because the transmitting
bridge port was not in the forwarding state
txFrames Number of frames that have been transmitted by this port to its
segment. A frame transmitted on the interface corresponding to
this port is only counted by this object if the frame is for a
protocol being processed by the local bridging function,
including bridge management frames.
txMcastFilters Number of frames discarded because of a user-defined packet
filter on the transmit multicast path of this port
txMtuExcDiscs Number of frames discarded by this port due to an excessive size
