This chapter describes Bridge Routing (BR) messages. For information on message content and how to use the message, refer to the Introduction.
| BR.001 |
Level: C-INFO
Short Syntax: BR.001 source_mac-> dest_mac drp, port block/list, nt network
Long Syntax: BR.001 Frame from source_mac to dest_mac dropped, received on blocked or listening port, network network
Description: A MAC frame has been received by the hardware, but is being dropped because the port on which it was received is in the "blocking" or "listening" state. Frames are only processed when the port is in the "learning" or "forwarding" state.
Cause: Normal on port bringup.
Action: Wait for port to transition to "learning" and "forwarding" states.
| BR.002 |
Level: P-TRACE
Short Syntax: BR.002 source_mac-> dest_mac drp, dst same LAN, nt network
Long Syntax: BR.002 Frame from source_mac to dest_mac dropped, destination on same LAN, network network
Description: A MAC frame has been received whose destination address is known to be on the same side of the bridge as the packet came from. It is dropped by the filtering logic since it does not need to be bridged. Note that this event is not counted by ELS for performance reasons. A counter is kept in ASRT, it is the ``Dropped, dest addr filtering'' entry in the ASRT>LIST SOURCE-ROUTE COUNTERS and ASRT>LIST TRANSPARENT COUNTERS commands.
Cause: Normal local traffic on network.
| BR.003 |
Level: UE-ERROR
Short Syntax: BR.003 source_mac-> dest_mac, brdg encap for rout prot IPX (802.3), drp, nt network
Long Syntax: BR.003 Frame from source_mac to dest_mac, WAN bridge encapsulation for routed protocol IPX (802.3), dropped, network network
Description: A frame has been received over a WAN interface in the Ethernet bridge encapsulation, but the IPX protocol (in 802.3 encapsulation) is routed by this node.
Cause: Configuration error at local or remote node with respect to bridging or routing particular protocols over the WAN link.
Action: All hosts on a WAN link must agree on whether to bridge or route a given protocol. Reconfigure as appropriate.
| BR.004 |
Level: P-TRACE
Short Syntax: BR.004 source_mac-> dest_mac prt IPX (802.3) filt, drp, nt network
Long Syntax: BR.004 Frame from source_mac to dest_mac, protocol IPX (802.3) filtered, dropped, network network
Description: A frame has been received for the IPX protocol (in 802.3 encapsulation), but the IPX protocol is being administratively filtered by the bridge. The frame will be dropped.
Cause: Frame received for filtered protocol.
| BR.005 |
Level: P-TRACE

| BR.006 |
Level: U-TRACE
Short Syntax: BR.006 Unreg dst source_mac-> dest_mac SNAP protocol_identifier, drp, nt network
Long Syntax: BR.006 Frame from source_mac to unregistered destination MAC address dest_mac, IEEE 802 SNAP Protocol Identifier protocol_identifier, dropped, network network
Description: A frame has been received for the IEEE 802 Subnetwork Access Protocol (SNAP) Protocol Identifier (PID) which corresponds with an enabled protocol, but the destination MAC address is not registered in the bridge. The frame will be dropped.
Cause: If dest_mac is a unicast address, a station on the LAN is sending frames for this protocol to the wrong next hop MAC address.
Action: Correct action of remote station.
Cause: If dest_mac is a multicast address, a station on the LAN may be sending frames to the wrong multicast address, or perhaps just to one that this router does not have enabled. Depending on the protocol, this may or may not be an error.
Action: Correct action of remote station, if necessary.

| BR.028 |
Level: UI-ERROR
Short Syntax: BR.028 No buf for endnode bridge, source_mac-> dest_mac, nt network, not bridged
Long Syntax: BR.028 No buffer to copy packet for endnode bridge and process, from source_mac to dest_mac, network network, not bridged
