- Description:
- This packet is generated when a packet is being sent out
the same network interface it arrived on. This router is
not the best path off that network to the destination network.
- Cause:
- Misconfigured first-hop router for end node on network.
- Action:
- Reconfigure node.
- Cause:
- Routing tables are inconsistent.

- 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.

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.
- Level:

- 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.
- Level:
- UI-ERROR
- Class:
- 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.
- 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.
- Level:
- C-TRACE
- Short Syntax:
- XN.019 protocol

- 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.
- Level:
- UE-ERROR
- Short Syntax:
- XN.020 protocol
bad src net 0, hop count hop_count
, source_net
/ source_node

- 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.
- Level:
- UE-ERROR
- Short Syntax:
- XN.021 protocol
inv len ( claimed_length
) frm source_net
/ source_node
- Long Syntax:
- XN.021 protocol
invalid length ( claimed_length
bytes) from source_net
/ source_node
- Description:
- This message is generated when a packet has a length field
in the XNS, IPX or DDS network layer header that is shorter than the 30 byte
minimum packet length.
- Cause:
- Programming error in remote node, corruption by network.
