MIB II statistics provided are:
In Octets (ifInOctets) The total number of octets (or bytes) of data
received at the selected LAN interface, expressed as a
rate (octets/second).
In Ucast (ifInUcastPkts) The total number of packets received at
the selected LAN interface that were destined for a single
address (unicast), expressed as a rate (packets/second).
In NUcast (ifInNUcastPkts) The total number of packets received at
the selected LAN interface that were destined for more
than one address (either broadcast or multicast),
expressed as a rate (packets/second).
In Discards (ifInDiscards) The total number of inbound packets which
were discarded even though no errors were detected,
expressed as a rate (packets/second); well-formed
packets are typically discarded in order to free up buffer
space.
In Errors (ifInErrors) The total number of inbound packets which
contained errors that prevented them from being
delivered, expressed as a rate (packets/second).
Out Octets (ifOutOctets) The total number of octets (or bytes) of data
transmitted by the selected LAN interface, expressed as a
