vctVcfrOoSeqPktCntExceeded
VC Tester Vcfr Oo Seq Packet Cnt Exceeded
1.3.6.1.4.1.562.2.4.1.5130.5.12.1.19
This attribute displays the number times that the out of sequence packet threshold is exceeded. When the threshold is exceeded, this condition is treated as if the loss frame timer has expired and all frames queued at the sink Vc are delivered to the AP. We need to keep this count to examine if the threshold is engineered properly. This should be used in conjunction with the peak value of out-of- sequenced queue and the number of times the loss frame timer has expired. This count should be relatively small when compared with loss frame timer expiry count.
