This object is a count of the number of octets
contained in invalid 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 icfVgPortIPMFrames or
icfVgPortDataErrorFrames. This counter can be
combined with icfVgPortHCReadableOctets to calculate
network utilization.
This counter is a 64 bit version of
icfVgPortUnReadableOctets. It should be used by
Network Management protocols which support 64 bit
counters (e.g. SNMPv2).
