Table 53 Layer 3 Statistics commands Command Usage *show layer3 counters Displays all Layer 3 statistics. Command mode: All except UserEXEC * indicates commands that are available only on the GbE2c Layer 2/3 Ethernet Blade Switch. IP statistics The following command displays IP statistics: show ip counters Command mode: All except User EXEC IP statistics: ipInReceives: 36475 ipInAddrErrors: 905 ipInUnknownProtos: 0 ipInDelivers: 4103 ipOutDiscards: 0 ipDefaultTTL: 255 ipInHdrErrors: 0 ipInDiscards: 0 ipOutRequests: 30974 The following table describes the IP statistics: Table 54 IP statistics Statistics ipInReceives ipInHdrErrors ipInAddrErrors ipInUnknownProtos ipInDiscards ipInDelivers ipOutRequests ipOutDiscards ipDefaultTTL Description The total number of input datagrams received from interfaces, including those received in error. The number of input datagrams discarded due to errors in their 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. The number of input datagrams discarded because the IP address in their IP header destination field was not a valid address to be received at this switch. This count includes invalid addresses (for example, 0.0.0.0) and addresses of unsupported classes (for example, Class E). For entities which are not IP gateways and therefore do not forward datagrams, this counter includes datagrams discarded because the destination address was not a local address. The number of locally addressed datagrams received successfully but discarded because of an unknown or unsupported protocol. 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 re-assembly. The total number of input datagrams successfully delivered to IP user-protocols (including ICMP). 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. 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 would include datagrams counted in ipForwDatagrams if any such packets met this (discretionary) discard criterion. The default value inserted into the Time-To-Live (TTL) field of the IP header of datagrams originated at this switch, whenever a TTL value is not supplied by the transport layer protocol.

Table 54
IP statistics
Statistics
Description
ipInReceives
The total number of input datagrams received from interfaces, including those received in
error.
ipInHdrErrors
The number of input datagrams discarded due to errors in their 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 their IP header
destination field was not a valid address to be received at this switch. This count includes
invalid addresses (for example, 0.0.0.0) and addresses of unsupported classes (for
example, Class E).
For entities which are not IP gateways and therefore do not forward datagrams, this
counter includes datagrams discarded because the destination address was not a local
address.
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 re-assembly.
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 would include datagrams counted in ipForwDatagrams if any such packets
met this (discretionary) discard criterion.
ipDefaultTTL
The default value inserted into the Time-To-Live (TTL) field of the IP header of datagrams
originated at this switch, whenever a TTL value is not supplied by the transport layer
protocol.
