This object is a count of the total number of octets
contained in invalid frames that have been received
on all ports in this repeater. This counter is the
summation of the values of icfVgPortUnreadableOctets
counter for all of the ports in this repeater.
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).
