Configuring Routing

Insight Managed 28-Port and 52-Port Gigabit Ethernet Smart Cloud Switches
The following table describes the nonconfigurable information displayed on the page.
Table 50. IP routing statistics information
Field Description
IpInReceives The total number of input datagrams received from interfaces, including those
received in error.
IpInHdrErrors The number of input datagrams discarded because of errors in IP headers,
including bad checksums, version number mismatch, other format errors,
time-to-live exceeded, errors discovered in processing their IP options, and so
on.
IpInAddrErrors The number of input datagrams discarded because the IP address in the 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.
IpForwDatagrams The number of input datagrams for which this entity was not the final IP
destination, which caused the switch to attempt to forward them to the final
destination. In entities that do not act as IP gateways, this counter includes only
those packets that were source-routed via this entity, and the source-route
option processing was successful.
IpInUnknownProtos The number of locally addressed datagrams received successfully but discarded
because of an unknown or unsupported protocol.
IpInDiscards The 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). This counter does not include any datagrams discarded
while awaiting reassembly.
IpInDelivers The total number of input datagrams successfully delivered to IP user-protocols
(including ICMP).
IpOutRequests The total number of IP datagrams that local IP user-protocols (including ICMP)
supplied to IP in requests for transmission. This counter does not include any
datagrams counted in ipForwDatagrams.
IpOutDiscards The number of output IP datagrams for which no problem was encountered to
prevent their transmission to their destination, but which were discarded (for
example, for lack of buffer space). This counter includes datagrams counted in
ipForwDatagrams if any such packets met this discretionary discard criterion.
IpOutNoRoutes The number of IP datagrams discarded because no route could be found to
transmit them to their destination. This counter includes any packets counted in
ipForwDatagrams that meet this no-route criterion. This includes any datagrams
that a host cannot route because all of its default gateways are down.
IpReasmTimeout The maximum number of seconds that received fragments are held while they
are awaiting reassembly at this entity.
IpReasmReqds The number of IP fragments received that needed to be reassembled at this
entity.
IpReasmOKs The number of IP datagrams successfully reassembled.
