| Description | 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
vgRptrPortIPMFrames, vgRptrPortOversizeFrames,
vgRptrPortNullAddressedFrames, or
vgRptrPortDataErrorFrames. This counter can be
combined with vgRptrPortReadableOctets to
calculate network utilization.
Note that this counter can roll over very
quickly. A management station is advised to
also poll the vgRptrPortUnreadOctetRollovers
object, or to use the 64-bit counter defined by
vgRptrPortHCUnreadableOctets instead of the two
32-bit counters.
This two-counter mechanism is provided for those
network management protocols that do not support
64-bit counters (e.g. SNMPv1). Note that
retrieval of these two counters in the same PDU
is NOT guaranteed to be atomic.
This counter may experience a discontinuity when
the value of the corresponding instance of
vgRptrPortLastChange changes. |
