Bridge Statistics
Port state—The operational state of the Ethernet bridged port, based on the
802.1D specification: disabled, listening, learning, forwarding, or blocking.
Total frames received—The total number of frames received at this port.
Broadcast Frames—The number of broadcast frames received on the port.
Spanning Tree Frames—The total number of 802.1D Bridge Protocol Data Unit
frames received by the bridged port since the statistics were last cleared.
Discarded Frames—The number of valid frames received that were discarded
(filtered) by the forwarding process.
Flooded Frames—The total number of incoming frames that were flooded on
this port.
Forwarded Frames—The number of incoming frames at this port that were
forwarded.
Total frames transmitted—The total number of frames transmitted at this port.
Filtering Statistics
MAC MTU Exceeded—The number of frames discarded because of a size greater
than the maximum MTU size for the port.
No ATM VCs present—The number of frames discarded because there was no
ATM VC associated with the physical port.
Bridge discards—The number of frames discarded due to the bridging operation.
Output port disabled—The number of frames discarded because the output
port was disabled.
Source address filtered—The number of frames discarded due to source address
filtering.
Destination address filtered—The number of frames discarded due to
destination address filtering.
SAP Filtered—The number of frames discarded due to the protocol filtering
operation.
