This object is a count of the number of octets
contained in good frames that have been received on
this port. This counter is incremented by OctetCount
for each frame received on this port which has been
determined to be a readable frame (i.e. each frame
counted by icfVgPortReadableFrames).
Note that this counter will roll over very quickly.
It is provided for backward compatibility for Network
Management protocols that do not support 64 bit
counters (e.g. SNMP version 1).
