-------- --------------- -------- -------- -------- -------- -------- --------
No Entries.
Header Errors Number of input datagrams discarded because of errors in their
XNS header, including bad checksums, version number mismatch,
format errors, and so on.
Address Errors Number of input datagrams discarded because the XNS address in
their XNS header’s destination field was not a valid address to be
received at this router. This count includes invalid addresses (such
as 0.0.0.0) and addresses of unsupported classes (such as Class E).
If a router is not an XNS Gateway and does not forward datagrams,
this value includes datagrams discarded because the destination
address was not a local address.
Unknown Protocol Number of locally addressed datagrams received successfully but
discarded because of an unknown or unsupported protocol.
In Discards Number of input XNS datagrams discarded because of an
environmental problem, such as lack of buffer resources. Doesn’t
include those discarded while awaiting reassembly.
Out Discards Number of output XNS datagrams discarded because of an
environmental problem, such as lack of buffer space. Includes
datagrams counted under Forwards in the “XNS Circuits Statistics”
table if they match this criterion.
No Routes Number of XNS datagrams discarded because the router could not
find a route to their destination. This value includes any packets
meeting this criterion under Forwards in the “XNS Circuits
Statistics” table. It also includes datagrams that a host could not
route because its default gateways were down.
