This object is a count of the number of octets
contained in normal priority frames that have been
received on this port. This counter is incremented
by OctetCount for each frame received on this port
which is counted by icfVgPortNormPriorityFrames.
This counter is a 64 bit version of
icfVgPortNormPriorityOctets. It should be used by
Network Management protocols which support 64 bit
counters (e.g. SNMPv2).
