IP Statistics
crc errors
The number of aligned frames discarded because of a CRC error.
align errors
The number of frames that are both misaligned and contain a CRC error.
resource errors
The number of good frames discarded because there were no resources available.
pkts xmit
The number of packets transmitted on the LAN port.
xmit errors
The number of packets transmitted with errors on the LAN port.

TATISTICS
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.

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).
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.
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.

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.
