rbnQosIfQueueTailDroppedOctets
Module: RBN-QOS-MIB
OID (symbolic): RBN-QOS-MIB::rbnQosIfQueueTailDroppedOctets
OID (numeric): 1.3.6.1.4.1.2352.2.22.1.2.1.6
Node type: OBJECT-TYPE
Type: Counter32
Access: read-only
Description: The number of octets dropped when the total number of packets in this queue was greater than the maximum threshold.
Discontinuities in the value of this counter can occur at re-initialization of the management system, and at other times as indicated by the value of ifCounterDiscontinuityTime.
What is rbnQosIfQueueTailDroppedOctets?
This counter tracks octets dropped from this interface transmit queue because the queue's packet count exceeded its maximum threshold (a hard tail-drop, as opposed to the earlier WRED drops). Admins watch this for growth as a sign the queue is fully saturated, a more severe congestion signal than WRED drops.
