vgRptrPortUnreadableOctets
Module: DOT12-RPTR-MIB
OID (symbolic): DOT12-RPTR-MIB::vgRptrPortUnreadableOctets
OID (numeric): 1.3.6.1.2.1.53.1.2.3.1.1.5
Node type: OBJECT-TYPE
Type: Counter32
Access: read-only
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.
What is vgRptrPortUnreadableOctets?
A 32-bit count of octets in invalid frames (IPM, oversize, null-addressed, or data-error) received on this port, useful combined with vgRptrPortReadableOctets to calculate network utilization; it can roll over quickly. An admin pairs this with vgRptrPortUnreadOctetRollovers, or uses the 64-bit vgRptrPortHCUnreadableOctets instead, to track bad-traffic volume on a port accurately.
