Monitoring IPX Interface Statistics
CoreWatch lets you obtain current statistics for
•
the number of incoming and outgoing IPX packets.
•
the number of IPX packets that had bad header information, incorrect checksums,
invalid structures, or other problems.
Table 42. IP Error Statistics Graph Abbreviations
Abbreviation
Description
InHdrErr
Incoming IP datagrams the SSR discarded because of
problems in their headers (such as bad checksums, version
number mismatching and other formatting errors, and
problems in processing IP options).
InAddrErr
Incoming IP datagrams the SSR discarded because the IP
header's destination field included an invalid IP address
(such as 0.0.0.0) or an IP address of an unsupported class
(such as Class E).
InUnkownProt
Incoming IP datagrams addressed to the SSR that were
received successfully but were discarded because of an
unknown or unsupported protocol.
InDiscards
Incoming IP datagrams the SSR discarded although no
errors had been detected to prevent the SSR from processing
them. Freeing buffer space is one possible reason for
discarding such datagrams.
This statistic does not include any datagrams discarded
while awaiting reassembly.
OutDiscards
Outgoing IP datagrams the SSR discarded because of lack of
buffer space.
OutNoRoutes
Outgoing or forwarded IP datagrams discarded because no
route could be found to transmit them to their destination.
The statistics shown for this item also include any datagrams
the SSR could not route because its default gateways are
down.
