Source Routing Transparent (SRT) Bridge

This chapter describes Source Routing Transparent (SRT) Bridge messages. For information on message content and how to use the message, refer to the Introduction.

SRT.001 

Level: UI-ERROR

Short Syntax: SRT.001 No buf to dup broadcast frame source_mac-> dest_mac to port port, nt network

Long Syntax: SRT.001 No buffer available to duplicate frame from source_mac to dest_mac on to port port, network network

Description: No buffer available to copy a frame in order to send a bridged frame on multiple interfaces. Bridged packets are sent on multiple interfaces either for multicast destination addresses, or in the case of certain static entries. No copy of this frame will be sent on the specified port and network.

Cause: Severe packet buffer shortage.

Action: Check memory statistics in GWCON to verify packet buffer level.

Cause: Traffic peak using all available buffers.

Action: This is the problem if this message occurs infrequently.

SRT.002 

Level: UI-ERROR

Short Syntax: SRT.002 Err error_code setting promsic mode on nt network

Long Syntax: SRT.002 Error code error_code trying to set promiscuous mode on network network

Description: The Spanning Tree Protocol requested setting this network into Learning state, but the command to the device failed. The error_code is a device-specific error code that may indicate what the error is.

Cause: Hardware failure or software bug.

Action: Contact customer service.

SRT.003 

Level: UI-ERROR

Short Syntax: SRT.003 Hw cache full on port port nt network

Long Syntax: SRT.003 Hardware cache full on port port network network

Description: A hardware cache used for internal filtering and learning detected a full condition while attempting to age entries.

Cause: Too many entries in hardware cache.

Action: Reduce resolution time period.

SRT.004 

Level: UI-ERROR

Short Syntax: SRT.004 No buf for command_name cmd to nt network

Long Syntax: SRT.004 No buffer available for command_name command to network network

Description: No buffer was available to send a command to the device. The possible command names are "D_CNFGSRB" (configure source-routing bridging), "SRT_ON" (promiscuous on), "SRT_INFORM" (learn capabilities of device), "SRT_SET_AGE" (set age for filtering database in device), "SRT_DECR_AGE" (do aging pass on filtering database in device), "SRT_ADD_ENTRY" (add static entry), "SRT_DEL_ENTRY" (delete entry, from console), "SRT_SEARCH_ENTRY" (search for particular entry, from console), and "SRT_LIST_ENTRY" (list contents of learning database in card). For commands "D_CNFGSRB" and "SRT_ON" the result will be that the interface may remain in the wrong state. A failure on "SRT_INFORM" could cause serious problems. For other commands the results will be less serious.

Cause: Severe packet buffer shortage.

Action: Check memory statistics in GWCON to verify packet buffer level.

Cause: Traffic peak using all available buffers.

Action: This is the problem if this message occurs infrequently.

SRT.005 

Level: UI-ERROR

Short Syntax: SRT.005 source_mac-> dest_mac send fld, rsn reason_code, port port nt network

Long Syntax: SRT.005 Sending Frame from source_mac to dest_mac failed, reason reason_code, on port port network network

Description: The sending of a packet being forwarded failed. The reason is the internal error code for the failure.

Cause: Miscellaneous handler error. (Reason code 1.)

Action: Check for error messages from handler for network_name.

Cause: Output queue overflow, or other flow control. (Reason code 2.)

Action: Alleviate congestion.

Cause: Network down. (Reason code 3.)

Action: See why handler thinks network is down.

Cause: Dropped by handler to avoid looping, or bad broadcast. (Reason code 4.)

Action: Check configuration.

Cause: Host down. (Reason code 5.)

Action: See why handler thinks host is down.

SRT.006 

Level: CI-ERROR

Short Syntax: SRT.006 Input q ovf source_mac-> dest_mac, dropped, nt network

Long Syntax: SRT.006 Input queue overflow on frame from source_mac to dest_mac, packet dropped from network network

Description: The input queue for frames to be forwarded is too long, and this frame has been dropped to attempt to alleviate the congestion.

Cause: Bursty traffic may be causing congestion.

Action: Wait for burst to subside.

Cause: Too much traffic for forwarder to forward.

Action: Reconfigure network. Increase speed of router.

Cause: Inadequate buffer resources.

Action: Examine memory statistics in GWCON.

SRT.008 

Level: CE-ERROR

Short Syntax: SRT.008 source_mac-> dest_mac too big ( reformatted_length > output_maximum) for port port nt network, dropped

Long Syntax: SRT.008 Frame from source_mac to dest_mac is too big (reformatted length reformatted_length bytes > output maximum size output_maximum bytes) for port port network network, dropped

Description: The specified frame is too large to send on this outgoing port and network. The reformatted_length is the size of the frame including MAC headers after any mapping of data link headers.

Cause: Host on network with large maximum frame size sending to host on network with smaller maximum frame size.

Action: Reconfigure sending host to not send such large frames. If frame is of a routable protocol supporting fragmentation (such as IP or ISO) or maximum frame size determination (DNA or XNS), convert to using routing instead of bridging.

Cause: Host on network with large maximum frame size sending to host via an intervening network with smaller maximum frame size.

Action: Reconfigure network to use networks with large maximum frame size (such as FDDI or 802.5) as the backbone networks. Reconfigure port costs in Spanning Tree Protocol to favor spanning trees via networks with large maximum frame sizes.

SRT.009 

Level: UE-ERROR

Short Syntax: SRT.009 source_mac-> dest_mac drp, nt network down

Long Syntax: SRT.009 Frame from source_mac to dest_mac dropped, input network network is down

Description: A frame has been received for bridging on a network that is down. It will be ignored.

Cause: A BPDU has been sent to the unicast address of the router on this interface.

Action: Correct action of sending node.

Cause: Internal state inconsistency.

SRT.010 

Level: P-TRACE

Short Syntax: SRT.010 source_mac-> dest_mac drp, src add flt, port port nt network

Long Syntax: SRT.010 Frame from source_mac to dest_mac dropped, source address filtered, port port network network

Description: A MAC frame has been received by the hardware, but is being dropped because the source MAC address is being administratively filtered by the bridge. The frame will be dropped.

Cause: Receipt of frame whose source MAC address matches the source filter.

SRT.011 

Level: U-TRACE

Short Syntax: SRT.011 source_mac-> dest_mac dropped, input port port nt network not forwarding

Long Syntax: SRT.011 Frame from source_mac to dest_mac dropped, input port port network network not in forwarding state

Description: A MAC frame was received on a port that is still only in "learning" state. Frames are only bridged when the input port is in "forwarding" state. While the port is still in "learning" state, they are only processed to learn the source addresses for the filtering database. The frame will not be bridged.

Cause: Normal part of transition to "forwarding" state.

SRT.012 

Level: U-INFO

Short Syntax: SRT.012 source_mac-> dest_mac dropped, output port port nt network not forwarding

Long Syntax: SRT.012 Frame from source_mac to dest_mac dropped, output port port network network not in forwarding state

Description: A MAC frame was being bridged, but the destination port was not in "forwarding" state. It will not be sent on that port.

Cause: Output port still in "learning" state.

Action: None needed, port will transition to "forwarding".

Cause: Static entry in filtering database points to port that is not in "forwarding" state.

SRT.013 

Level: P-TRACE

Short Syntax: SRT.013 source_mac-> dest_mac drp, dst same LAN, port port nt network

Long Syntax: SRT.013 Frame from source_mac to dest_mac dropped, destination on same LAN, port port 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.

Cause: Normal local traffic on network.

SRT.014 

Level: CI-ERROR

Short Syntax: SRT.014 source_mac-> dest_mac drp, dst port port not enabled, nt network

Long Syntax: SRT.014 Frame from source_mac to dest_mac dropped, destination port port not enabled, network network

Description: A frame being bridged was destined for a port which is not running transparent bridging, or not in "forwarding" state for transparent bridging.

Cause: Static entry in filtering database points to port that is not in "forwarding" state.

SRT.015 

Level: P-TRACE

Short Syntax: SRT.015 source_mac-> dest_mac brdg port port nt network to port port nt network

Long Syntax: SRT.015 Frame from source_mac to dest_mac bridged from port number port network network to port number port network network

Description: A frame is being bridged between these two interfaces. The destination address was known, so it was sent only to the correct destination network.

SRT.016 

Level: P-TRACE

Short Syntax: SRT.016 source_mac-> dest_mac brdg-all port port nt network to port port nt network

Long Syntax: SRT.016 Frame from source_mac to dest_mac bridged to all ports from port number port network network to port number port network network

Description: A frame is being transparently bridged to all active transparent bridging ports. This happens when the frame destination is a multicast, when the frame destination is not in the learning database, or when required by static entries in the learning database. There will be one message for each port the frame is sent on.

SRT.017 

Level: U-INFO

Short Syntax: SRT.017 Enabling SRT on port port nt network

Long Syntax: SRT.017 Enabling SRT on port port network network

Description: The SRT forwarder is starting the process of enabling bridging on the specified interface. This starts when the interface comes up from a self-test.

SRT.018 

Level: C-INFO

Short Syntax: SRT.018 SRT startup complete on port port nt network

Long Syntax: SRT.018 SRT startup complete on port port network network

Description: The SRT forwarder has completed the process of enabling bridging on the specified interface. It will now enter "blocking" state.

SRT.019 

Level: UI-ERROR

Short Syntax: SRT.019 Unsupp ifc typ type_name, nt network

Long Syntax: SRT.019 Unsupported interface type type_name, network network

Description: The SRT forwarder had been enabled on a type of interface it does not support.

Cause: Enabling SRT on an interface which does not support SRT, such as ProNET-10.

SRT.020 

Level: UI-ERROR

Short Syntax: SRT.020 Can't autocfg brdg addr, lowest port port nt network no MAC addr

Long Syntax: SRT.020 Cannot autoconfigure the bridge address, the lowest numbered port port network network has no MAC address

Description: The user has configured the bridge to autoconfigure the bridge address based on the MAC address of the lowest number port. However, the lowest numbered port is of a type that does not have a MAC address, such as a serial line.

Action: Assign address to bridge by using SRT config> command "SET BRIDGE".

SRT.022 

Level: UI-ERROR

Short Syntax: SRT.022 Bridge config with no valid ports, disabling

Long Syntax: SRT.022 Bridge configured with no valid ports, disabling the bridge

Description: The bridge has been enabled, but there are no ports configured on that bridge or there was a mismatch between the interface and bridge port configuration records. The bridge will be left disabled.

Action: Resolve configuration conflicts between bridge ports and devices.

SRT.023 

Level: UI-ERROR

Short Syntax: SRT.023 Port port config on nonexist network number network_number

Long Syntax: SRT.023 Port port configured on nonexistent network number network_number

Description: The port has been configured to use a network that has not been configured with the Config> ADD DEVICE command. This port of the bridge will be disabled.

Cause: Inconsistency between router device configuration and bridge configuration.

Action: Correct the network number in the bridge configuration, or add the network in the device configuration.

SRT.024 

Level: UI-ERROR

Short Syntax: SRT.024 existent_port_count ports is < 2, disabling

Long Syntax: SRT.024 existent_port_count existent ports is less than 2, disabling bridge

Description: Less than two (valid) ports have been configured on the bridge. There must be at least two ports.

Cause: Less than two ports configured.

Action: Add more ports, or don't try and use bridging.

Cause: Too many ports on non-configured devices.

Action: Resolve configuration conflicts between bridging ports and devices.

SRT.025 

Level: UI-ERROR

Short Syntax: SRT.025 No mem for filt db (req requested_size, min minimum_size), disabl

Long Syntax: SRT.025 No memory for filtering databse (desired size requested_size bytes, absolute minimum size minimum_size bytes), disabling bridge

Description: There is not enough free memory to allocate even a minimal size filtering database. The bridge will be disabled. The bridge starts by trying to allocate requestd_size bytes, and then tries with progressively smaller sizes down to minimum_size. The minimum size is enough only for the registered and static entries.

Cause: Severe shortage of memory.

Action: Reduce routing table sizes in other protocols, use system with less protocols, expand memory in router.

SRT.026 

Level: C-INFO

Short Syntax: SRT.026 source_mac== dest_mac, drop, port port nt network

Long Syntax: SRT.026 Frame from source_mac to dest_mac, source same as destination, dropping, from port port network network

Description: Frames to and from the same address are not bridged by this bridge.

SRT.027 

Level: P-TRACE

Short Syntax: SRT.027 Chg state old_state to new_state, port port nt network

Long Syntax: SRT.027 Changing port state from old_state to new_state for port port, network network

Description: The Spanning Tree Protocol has requested this state change for this port in the SRT bridge. The old_state and new_state are one of: FORWARDING (Spanning Tree Protocol Forwarding state), LEARNING (Spanning Tree Protocol Learning state), LISTENING (Spanning Tree Protocol Listening state), BLOCKED (Spanning Tree Protocol Blocking state), CONFIGURING (configuration of port device pending), POSTCONFIGURING (configuration of port device done), PRECONFIGURING (port enabled, configuration of port device to start), and DISABLED (port disabled).

SRT.028 

Level: UI_ERROR

Short Syntax: SRT.028 No room for PERM mac_address in filt database, disabling

Long Syntax: SRT.028 No room for permanent address mac_address in filtering database, disabling bridge

Description: There is no room for the permanent entry in the filtering database. The bridge will be disabled.

Cause: Filtering database size too small.

Action: Make filtering database larger.

Cause: Too many permanent entries.

Action: Configure less permanent entries.

SRT.029 

Level: UI_ERROR

Short Syntax: SRT.029 No mem for PERM mac_address, disabling

Long Syntax: SRT.029 No memory for permanent address mac_address, disabling bridge

Description: There is no room for the permanent entry in an auxiliary database. The bridge will be disabled.

Cause: Too little free memory.

Action: Make routing databases smaller.

Action: Increase memory size.

Cause: Too many permanent entries.

Action: Configure less permanent entries.

SRT.030 

Level: UI-ERROR

Short Syntax: SRT.030 command Cmd fld to net network

Long Syntax: SRT.030 command command failed to network network

Description: A command to a network device failed. The possible command names are "SRT_ON" (promiscuous on), "SRT_OFF" (promiscuous off), "SRT_INFORM" (learn capabilities of device), "SRT_ADD_ENTRY" (add static entry in device), "SRT_SET_AGE" (set age for filtering database in device), and "SRT_DECR_AGE" (do aging pass on filtering database in device). For commands "SRT_ON" and "SRT_OFF" the result will be that the interface may remain in the wrong state. A failure on "SRT_INFORM" could cause serious problems. For other commands the results will be less serious.

Cause: Hardware failure or software bug.

Action: Contact customer service.

SRT.031 

Level: UI-ERROR

Short Syntax: SRT.031 No buf to dup routing_type frame source_mac-> dest_mac to port port, nt network

Long Syntax: SRT.031 No buffer available to duplicate routing_type frame from source_mac to dest_mac on to port port, network network

Description: No buffer available to copy a frame in order to send an All Routes Explorer (ARE) or Spanning Tree Explorer (STE) routing_type frame on multiple interfaces. ARE frames are sent on all interfaces which are part of the SRT spanning tree, STE frames are sent on all interfaces running source-routing. No copy of this frame will be sent on the specified port and network.

Cause: Severe packet buffer shortage.

Action: Check memory statistics in GWCON to verify packet buffer level.

Cause: Traffic peak using all available buffers.

Action: This is the problem if this message occurs infrequently.

SRT.032 

Level: UI-ERROR

Short Syntax: SRT.032 SR source_mac-> dest_mac send fld, rsn reason_code, port port nt network

Long Syntax: SRT.032 Sending source routed frame from source_mac to dest_mac failed, reason reason_code, on port port network network

Description: The sending of a source routed frame being forwarded failed. The reason_code is the internal error code for the failure.

Cause: Miscellaneous handler error. (Reason code 1.)

Action: Check for error messages from handler for network_name.

Cause: Output queue overflow, or other flow control. (Reason code 2.)

Action: Alleviate congestion.

Cause: Network down. (Reason code 3.)

Action: See why handler thinks network is down.

Cause: Dropped by handler to avoid looping, or bad broadcast. (Reason code 4.)

Action: Check configuration.

Cause: Host down. (Reason code 5.)

Action: See why handler thinks host is down.

SRT.033 

Level: C-TRACE

Short Syntax: SRT.033 routing_type dup RD drop source_mac-> dest_mac from port port, nt network

Long Syntax: SRT.033 routing_type with duplicate Route Descriptor from source_mac to dest_mac from port port, network network

Description: A source-routed frame having a All Routes Descriptor (ARE) or Spanning Tree Explorer (STE) routing_type in the RIF has a duplicate Routing Descriptor in the RIF. The frame will be dropped. This is a normal occurrence for ARE frames when there are any duplicate paths in the source routing domain. For STE frames, this indicates that there is an interface that is part of the source-routing spanning tree that should not be.

Cause: Receiving an ARE/STE from a segment is has already been on.

Action: None needed for ARE, this is normal. For STE, one may want to correct it's "spanning tree," but this is not essential.

SRT.034 

Level: UE-ERROR

Short Syntax: SRT.034 SRF dup LOUT (RIF RIF) drop source_mac-> dest_mac from port port, nt network

Long Syntax: SRT.034 SRF with duplicate LOUT (RIF RIF) from source_mac to dest_mac from port port, network network

Description: A source-routed frame of Specifically-routed frame (SRF) type has a duplicate LOUT (outgoing LAN ID). This is illegal, and the frame will be dropped.

Cause: Station sending frame with invalid RIF that would go through the same bridge more than once, thus looping forever.

Action: Find out why station is using this RIF. Either it is using a hand-configured one that is wrong, or there is a bug in the discovery algorithm.

SRT.036 

Level: UE-ERROR

Short Syntax: SRT.036 STE max RD (RIF RIF) drop source_mac-> dest_mac from port port, nt network

Long Syntax: SRT.036 Spanning Tree Explorer exceeds maximum Route Descriptors (RIF RIF) from source_mac to dest_mac from port port, network network

Description: A Spanning Tree Explorer (STE) source-routed frame has more Route Descriptors than this bridge is configured to allow for STE frames. The frame will be dropped.

Cause: Upstream bridge has an STE RD limit inconsistent with this bridge.

Action: Reconfigure all bridges in source-routing domain to have consistent STE RD limit.

Cause: Network has too many hops for configured STE RD limit.

Action: Reconfigure all bridges in source-routing domain to have STE RD limit consistent with the diameter of the domain.

SRT.037 

Level: CE-ERROR

Short Syntax: SRT.037 SRF unk LOUT (RIF RIF) drop source_mac-> dest_mac from port port, nt network

Long Syntax: SRT.037 SRF with unknown LOUT (RIF RIF) from source_mac to dest_mac from port port, network network

Description: A source-routed frame of Specifically-routed frame (SRF) type has an outgoing LOUT (LAN ID Out) that does not match that of any active source-routing interface in the router. It will be dropped.

Cause: End station using RIF that was discovered before an interface went down in the router.

Action: None should be needed, the session on the station will fail, and it will re-initiate route discovery.

Cause: More than one bridge on the incoming segment with the same bridge number, and this LOUT matches in it.

Action: Reconfigure for legal configuration. All Bridge Numbers must be unique on a given segment.

Cause: End station using completely invalid RIF.

Action: Find out why station is using this RIF.

SRT.038 

Level: P-TRACE

Short Syntax: SRT.038 ARE rcv (RIF RIF) source_mac-> dest_mac from port port, nt network

Long Syntax: SRT.038 All Routes Explorer received (RIF RIF) from source_mac to dest_mac from port port, network network

Description: An All Routes Explorer frame has been received on the specified port.

SRT.039 

Level: P-TRACE

Short Syntax: SRT.039 ARE sent (RIF RIF) source_mac-> dest_mac to port port, nt network

Long Syntax: SRT.039 All Routes Explorer sent (RIF RIF) from source_mac to dest_mac to port port, network network

Description: An All Routes Explorer frame has been sent on the specified port.

SRT.040 

Level: P-TRACE

Short Syntax: SRT.040 STE rcv (RIF RIF) source_mac-> dest_mac from port port, nt network

Long Syntax: SRT.040 Spanning Tree Explorer received (RIF RIF) from source_mac to dest_mac from port port, network network

Level: P-TRACE

Short Syntax: SRT.041 STE sent (RIF RIF) source_mac-> dest_mac to port port, nt network

Long Syntax: SRT.041 Spanning Tree Explorer sent (RIF RIF) from source_mac to dest_mac to port port, network network

Description: A Spanning Tree Explorer frame has been sent on the specified port.

SRT.042 

Level: U-INFO

Short Syntax: SRT.042 routing_type LF lowered ( old_LF to new_LF) source_mac-> dest_mac from port port, nt network

Long Syntax: SRT.042 routing_type Largest Frame size lowered (from old_LF bytes to new_LF bytes) from source_mac to dest_mac from port port, network network

Description: A source-routing explorer (ARE or STE in routing_type) has had the Largest Frame (LF) field lowered in its RIF. This happens whenever a frame is received from a segment with a smaller maximum frame size than the one presently encoded in the LF bits. This is a normal part of the spanning tree protocol to determine the maximum frame size on all routes.

Cause: It is somewhat abnormal to see this happen on received frames, and indicates that the endnodes or other bridges on this segment have different frame sizes configured. However, it is a perfectly legal configuration.

Action: Make frame size configurations consistent on a given segment.

SRT.043 

Level: C-INFO

Short Syntax: SRT.043 routing_type LF lowered ( old_LF to new_LF) source_mac-> dest_mac to port port, nt network

Long Syntax: SRT.043 routing_type Largest Frame size lowered (from old_LF bytes to new_LF bytes) from source_mac to dest_mac to port port, network network

Description: A source-routing explorer (ARE or STE in routing_type) has had the Largest Frame (LF) field lowered in its RIF. This happens whenever a frame is sent to a segment with a smaller maximum frame size than the one presently encoded in the LF bits. This is a normal part of the spanning tree protocol to determine the maximum frame size on all routes.

SRT.044 

Level: P-TRACE

Short Syntax: SRT.046 routing_type rcv source_mac-> dest_mac from disabl port port, nt network, disc

Long Syntax: SRT.046 routing_type frame received from source_mac to dest_mac on disabled port port, network network, discarded

Description: A source-routed frame has been received on the specified port, but that port is not configured for bridging. The routing_type is one of SRF (Specifically-routed frame), STE (Spanning Tree Explorer), or ARE (All Routes Explorer). This really should not happen on more than a transient basis, because ports that are not enabled for bridging should not be queueing packets to the source-routing forwarder.

SRT.047 

Level: UI-ERROR

Short Syntax: SRT.047 routing_type rcv source_mac-> dest_mac from non-SR port port, nt network, disc

Long Syntax: SRT.047 routing_type frame received from source_mac to dest_mac on non-source-routing port port, network network, discarded

Description: A source-routed frame has been received on the specified port, but that port is not configured for source-routing bridging. The routing_type is one of SRF (Specifically-routed frame), STE (Spanning Tree Explorer), or ARE (All Routes Explorer). This really should not happen on more than a transient basis, because ports that are not enabled for bridging should not be queueing packets to the source-routing forwarder.

SRT.048 

Level: P-TRACE

Short Syntax: SRT.048 STE dropped (RIF RIF) source_mac-> dest_mac from blk port port, nt network

Long Syntax: SRT.048 Spanning Tree Explorer dropped (RIF RIF) from source_mac to dest_mac from blocked port port, network network

Description: A Spanning Tree Explorer (STE) frame was dropped, and not forwarded, because the incoming port is not part of the spanning tree, or has been configured not to forward STE frames.

Cause: Normal for STE frames, this is the difference between them and ARE frames.

SRT.050 

Level: UI-ERROR

Short Syntax: SRT.050 err error_string ena SR on nt network

Long Syntax: SRT.050 Got error_string error trying to enable source-routing on network network

Description: The bridge tried to enable source-routing bridging on this interface, but the interface refused the configuration command. Source-routing will be left disabled on this interface.

Cause: Either bad commands were passed to the interface, or there is a bug in the interface firmware.

Action: Contact customer service.

SRT.051 

Level: UE-ERROR

Short Syntax: SRT.051 SRF source_mac-> dest_mac too big ( reformatted_length > output_maximum) for port port nt network, dropped

Long Syntax: SRT.051 Specifically-routed frame from source_mac to dest_mac is too big (reformatted length reformatted_length > output maximum size output_maximum) for port port network network, dropped

Description: The specified Specifically-routed (source-routed) frame is too large to send on this outgoing port and network. The reformatted_length is the size of the frame including MAC headers after any mapping of data link headers.

Cause: Host not honoring LF bit values from its returned explorer frames.

Action: Fix host.

SRT.052 

Level: UE-ERROR

Short Syntax: SRT.052 routing_type source_mac-> dest_mac too big ( reformatted_length > output_maximum) for port port nt network, dropped

Long Syntax: SRT.052 routing_type frame from source_mac to dest_mac is too big (reformatted length reformatted_length > output maximum size output_maximum) for port port network network, dropped

Description: The source-routed explorer (ARE or STE routing_type) frame is too large to send on this outgoing port and network. The reformatted_length is the size of the frame including MAC headers after any mapping of data link headers.

Cause: The sending host is putting too much data in its explorer frames. These should normally be short, since it should not be making any assumptions about the maximum frame size available.

Action: Correct behavior of sending host.

SRT.053 

Level: UI-ERROR

Short Syntax: SRT.053 routing_type inv RIF len RIF_length, source_mac-> dest_mac port port, nt network, disc

Long Syntax: SRT.053 routing_type with invalid RIF lenth RIF_length from source_mac to dest_mac from port port, network network, discarded

Description: A source-routing frame was received with an invalid RIF length encoded in the Length bits of the RIF. The routing_type is one of SRF (Specifically-routed frame), STE (Spanning Tree Explorer), or ARE (All Routes Explorer).

Cause: Received frame with RIF length less than 2 or not a multiple of 2 in length.

Action: Correct software in sending node.

SRT.054 

Level: UI-ERROR

Short Syntax: SRT.054 No mem for hash tab (req requested_size), disabl

Long Syntax: SRT.054 No memory for hash table (desired size requested_size bytes), disabling bridge

Description: There is not enough free memory to allocate the hash table for the filtering database. The bridge will be disabled.

Cause: Severe shortage of memory.

Action: Reduce routing table sizes in other protocols, use system with less protocols, expand memory in router.

SRT.055 

Level: UI-ERROR

Short Syntax: SRT.055 No mem for conv hash tab (req requested_size), disabl

Long Syntax: SRT.055 No memory for conversion hash table (desired size requested_size bytes), disabling bridge

SRT.056 

Level: CI-ERROR

Short Syntax: SRT.056 Input SR q ovf source_mac-> dest_mac, dropped, nt network

Long Syntax: SRT.056 Input source-routing queue overflow on frame from source_mac to dest_mac, packet dropped from network network

Description: The input queue for source-routed frames to be forwarded is too long, and this frame has been dropped to attempt to alleviate the congestion.

Cause: Bursty traffic may be causing congestion.

Action: Wait for burst to subside.

Cause: Too much traffic for forwarder to forward.

Action: Reconfigure network. Increase speed of router.

Cause: Inadequate buffer resources.

Action: Examine memory statistics in GWCON.

SRT.057 

Level: P-TRACE

Short Syntax: SRT.057 source_mac-> dest_mac brdg port port nt network to port port nt network

Long Syntax: SRT.057 Frame from source_mac to dest_mac bridged from port number port network network to port number port network network

Description: A frame is being bridged between these two interfaces. The destination address was known, so it was sent only to the correct destination network.

SRT.058 

Level: CE-ERROR

Short Syntax: SRT.058 TB->SR source_mac-> dest_mac too big ( reformatted_length > output_maximum) for port port nt network, drop

Long Syntax: SRT.058 Transparent frame converted to source-routed frame from source_mac to dest_mac is too big (reformatted length reformatted_length bytes > output maximum size output_maximum bytes) for port port network network, dropped

Description: The specified transparent bridge frame is too large to send as a source-routed frame on this outgoing port and network. The reformatted_length is the size of the frame including MAC headers and RIF after any mapping of data link headers.

Cause: Host on network with large maximum frame size sending to host on network with smaller maximum frame size.

Action: Reconfigure sending host to not send such large frames. If frame is of a routable protocol supporting fragmentation (such as IP or ISO) or maximum frame size determination (DNA or XNS), convert to using routing instead of bridging.

Cause: Host on network with large maximum frame size sending to host via an intervening network with smaller maximum frame size.

Action: Reconfigure network to use networks with large maximum frame size (such as FDDI or 802.5) as the backbone networks. Reconfigure port costs in Spanning Tree Protocol to favor spanning trees via networks with large maximum frame sizes.

Long Syntax: SRT.061 Specifically routed frame frame received from source_mac to dest_mac (RIF RIF) to disabled port port, network network, discarded

Description: A Specifically Routed frame has been received whose RIF would send it on the specified port, but that port is not configured for bridging.

Cause: End station using invalid RIF. This can happen when the end station acquires a RIF, and caches it, but in the interim the bridge has been reconfigured and restarted.

SRT.062 

Level: CE-ERROR

Short Syntax: SRT.062 Warning:SR->TB source_mac-> dest_mac too big ( reformatted_length > output_maximum) from port port nt network

Long Syntax: SRT.062 Source-routed frame converted to transparent frame from source_mac to dest_mac is too big (reformatted length reformatted_length bytes > output maximum size output_maximum bytes) from port port network network, may get dropped.

Description: The specified source-routed frame is larger than that is allowed by LF-BIT configuration for the transparent bridge domain. After mapping to the MAC headers of the outgoing port, the packet may get dropped if it exceeds the MSDU limit of the port.

Cause: Source-routing host not honoring maximum frame size that was determined in source-routing threading process.

Action: Correct behavior of host.

Cause: Host on network with large maximum frame size sending to host on network with smaller maximum frame size.

Action: Reconfigure sending host to not send such large frames. If frame is of a routable protocol supporting fragmentation (such as IP or ISO) or maximum frame size determination (DNA or XNS), convert to using routing instead of bridging.

Cause: Host on network with large maximum frame size sending to host via an intervening network with smaller maximum frame size.

Action: Reconfigure network to use networks with large maximum frame size (such as FDDI or 802.5) as the backbone networks. Reconfigure port costs in Spanning Tree Protocol to favor spanning trees via networks with large maximum frame sizes.
