Configuring IP Routing (Layer 3)
7-22 Cajun P550/P220 Switch Operation Guide
IP In Address Errors Number of input datagrams discarded because the IP address in
their IP header's destination field was not a valid address to be
received at this entity. This count includes invalid addresses (for
example, 0.0.0.0) and addresses of unsupported Classes (for
example, Class E). For entities that are not IP Gateways and
therefore do not forward datagrams, this counter includes
datagrams discarded because the destination address was not a
local address.
IP Forward Datagrams Number of input datagrams for which this entity was not their
final IP destination, as a result of which an attempt was made to
find a route to forward them to that final destination. In entities
which do not act as IP Gateways, this counter will include only
those packets which were Source-Routed via this entity, and the
Source-Route option processing was successful.
Note: This is routed by the supervisor in the software.
IP In Unknown Protocols Number of input datagrams discarded due to errors in their IP
headers. Such errors may include bad checksums, version number
mismatches, other format errors, time-to-live exceeded, errors
discovered in processing their IP options.
IP In Discards Number of input IP datagrams for which no problems were
encountered to prevent their continued processing, but which
were discarded (for example, for lack of buffer space).
Note: This counter does not include any datagrams discarded
while awaiting re-assembly.
IP In Delivers Total number of input datagrams successfully delivered to IP
user-protocols (including Internet Control Message Protocol
(ICMP)).
IP Out Requests Total number of IP datagrams that local IP user-protocols
(including ICMP) supplied to IP in requests for transmission.
Note: This counter does not include any datagrams counted in
ipForwDatagrams.
IP Out Discards Number of output IP datagrams for which no problem was
encountered to prevent their transmission to their destination, but
were discarded (for example, for lack of buffer space). Note that
this counter includes datagrams counted in ipForwDatagrams if
any such packets met this (discretionary) discard criterion.
IP Out No Routes Number of IP datagrams discarded because no route could be
found to transmit them to their destination. Note that this counter
includes any packets counted in ipForwDatagrams which meet this
`no-route' criterion. Note that this includes any Datagrams which a
host cannot route because all of its default gateways are down.
IP Reassembly Timeout Maximum number of seconds that received fragments are held
while they are awaiting reassembly at this entity.
IP Reassembly Required Number of IP fragments received that need to be reassembled.
