USER’S GUIDE

IP STATISTICS

You can access IP statistics by using the ip stats console command. These statistics are parts of the IP Group and the ICMP Group MIB variables that are defined in RFC-1213:MIB-II.

IP GROUP STATISTICS

ipForwarding

The indication of whether the system is acting as an IP gateway in respect to the forwarding of datagrams received by, but not addressed to, this CyberSWITCH. IP gateways forward datagrams, IP hosts do not (except those source-routed via the host).

ipDefaultTTL

The default value inserted into the Time-To-Live field of the IP header of datagrams originated at this system, whenever a TTL value is not supplied by the transport layer protocol.

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. Possible errors include bad checksums, version number mismatches, other format errors, time-to-live exceeded, errors discovered in processing their IP options, etc.

ipInAddrErrors

The 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 system. This count includes invalid addresses (e.g., 0.0.0.0) and addresses of unsupported Classes (e.g., Class E). For systems 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 system 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 systems that do not act as IP Gateways, this counter will include only those packets that were Source- Routed via this system, 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 that would prevent their continued processing, but which were discarded (e.g., for lack of buffer space). Note that this counter does not include any datagrams discarded while awaiting re-assembly.

ipInDelivers

The total number of input datagrams successfully delivered to IP device-protocols (including ICMP).
