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).
This counter is a 64 bit version of
icfVgPortReadableOctets. It should be used by
Network Management protocols which support 64 bit
counters (e.g. SNMPv2).
