This chapter describes Xerox Network Core (XN) messages. For information on message content and how to use the message, refer to the Introduction.
| XN.001 |
Level: UE-ERROR
Short Syntax: XN.001 protocol trunc pkt frm source_net/ source_node, xns length phys length
Long Syntax: XN.001 protocol truncated packet from source_net/ source_node; xns length, physical length
Description: This message is generated when a packet has an XNS packet length greater then the packets physical length.
Cause: Programming error in remote node, truncation by network.
| XN.004 |
Level: UE-ERROR
Short Syntax: XN.004 protocol hop cnt ovflo frm source_net/ source_node to destination_net
Long Syntax: XN.004 protocol hop count overflow from source_net/ source_node to destination_net
Description: This message is generated when a packet's hop count counts up past 15 and overflows. An Error (hop count) packet will be sent.
| XN.005 |
Level: CE-ERROR
Short Syntax: XN.005 protocol no gwy frm source_net/ source_node to destination_net
Long Syntax: XN.005 protocol no gateway from source_net/ source_node to destination_net
Description: This message is generated when a packet cannot be forwarded because there is no gateway to the destination network. An Error (unreachable) packet will be sent.
| XN.007 |
Level: UE-ERROR
Short Syntax: XN.007 protocol dst hst 0 frm source_net/ source_node to destination_net
Long Syntax: XN.007 protocol destination host 0 from source_net/ source_node to destination_net
Description: This message is generated when a packet is addressed to node 000000000000. This is an illegal host address. An Error (checksum) packet will be sent.
| XN.008 |
Level: P-TRACE
Short Syntax: XN.008 protocol source_net/ source_node -> dest_net/ dest_node
Long Syntax: XN.008 protocol Packet received from source_net/ source_node for dest_net/ dest_node
Description: This message is generated when a packet is forwarded.
| XN.009 |
Level: UE-ERROR
Short Syntax: XN.009 protocol pkt too lng to frwd pkt_size > max_size nt output network ID frm source_net/ source_node
Long Syntax: XN.009 protocol packet too long to forward pkt_size > max_size net output network ID from source_net/ source_node
Description: This message is generated when a forwarded packet cannot be sent out the required interface because it is too long. An Error (size) packet will be sent.
| XN.010 |
Level: UI-ERROR
Short Syntax: XN.010 protocol type frm source_net/ source_node for dest_net/ dest_node dsc, rsn code
Long Syntax: XN.010 protocol type from source_net/ source_node for dest_net/ dest_node discarded for reason code
Description: An outgoing packet was not successfully transmitted for the reason indicated by the error code.
| XN.011 |
Level: C-INFO
Short Syntax: XN.011 protocol intrfc network/ node nt network ID up
Long Syntax: XN.011 protocol interface network/ node net network ID up
Description: The specified interface has come up, and has been enabled for the specified XNS protocol.
| XN.012 |
Level: U-INFO
Short Syntax: XN.012 protocol del nt destination_net rt via gateway nt network ID
Long Syntax: XN.012 protocol deleted net destination_net route via gateway net network ID
Description: The specified route has been deleted because the first hop interface for that route has gone down.
Cause: Interface down.
Action: Fix network.
| XN.013 |
Level: UI-ERROR
Short Syntax: XN.013 protocol tbl ovrfl, dst destination_net
Long Syntax: XN.013 protocol Table overflow, destination destination_net
Description: This message is generated when a new entry cannot be made to routing table because it is already full.
Cause: Routing table too small.
Action: Increase routing table size for this protocol.
| XN.014 |
Level: C-INFO
Short Syntax: XN.014 protocol echo typ operation to skt socket frm source_net/ source_node
Long Syntax: XN.014 protocol Echo type operation to socket socket from source_net/ source_node
Description: A packet of the echo type has been received with the specified operation to the specified socket.
| XN.015 |
Level: UE-ERROR
Short Syntax: XN.015 protocol bd src source_net/ source_node nt network ID
Long Syntax: XN.015 protocol bad source source_net/ source_node net network ID
Description: A packet was being returned to the sender, but the senders node address was a multicast address or the illegal address 000000000000. This can happen when sending an Echo reply, an Error packet, or replying to other queries. The packet will be discarded.
| XN.016 |
Level: UE-ERROR
Short Syntax: XN.016 protocol bad net 0 source_net/ source_node-> dest_net/ dest_node
Long Syntax: XN.016 protocol bad source network 0 from source_net/ source_node for dest_net/ dest_node
Description: A packet was being returned to the sender, and the source network was zero, but the destination network was non-zero. This can happen when sending an Echo reply, an Error packet, or replying to other queries. The packet will be discarded.
| XN.017 |
Level: UI-ERROR
Level: OOM
Short Syntax: XN.017 protocol no mem for err pkt
Long Syntax: XN.017 protocol No memory for error packet
Description: This message is generated when no memory is available to copy the offending packet into an Error packet. An Error packet will not be sent.
| XN.018 |
Level: UE-ERROR
Short Syntax: XN.018 protocol short ( length) pkt frm source_net/ source_node (?) nt network ID
Long Syntax: XN.018 protocol short ( length) packet from source_net/ source_node (?) net network ID
Description: This message is generated when a packet has a physical length shorter than the minimum 30 byte XNS, IPX, or DDS header length. The source_net and source_node may or may not be valid packet data, depending on how severe the truncation is.
Cause: Programming error in remote node, truncation by network.
| XN.019 |
Level: C-TRACE
Short Syntax: XN.019 protocol chg src net to new_source_net, pkt source_net/ source_node -> dest_net/ dest_node
Long Syntax: XN.019 protocol changing source network to new_source_net on packet received from source_net/ source_node for dest_net/ dest_node
Description: This message is generated when an IPX packet is received with a source network number of 0. The router corrects this to be the network number of the interface the packet was received on.
| XN.020 |
Level: UE-ERROR
Short Syntax: XN.020 protocol bad src net 0, hop count hop_count, source_net/ source_node -> dest_net/ dest_node, nt network ID
Long Syntax: XN.020 protocol bas source network 0 with hop count hop_count on packet received from source_net/ source_node for dest_net/ dest_node via network network ID
Description: This message is generated when an IPX packet is received with a source network number of 0, and the hop count (transport control) is non-zero. The source network number will not be corrected, since it is probably not the network it was received on. The dest_node will be unable to reply.
Cause: This would indicate that the packet has already been forwarded by another router that does not correct the source network number when forwarding, or that the originating node sent the packet with a non-zero hop count.
Action: Correct programming error at remote node or router.
