If you do a "sh queueing int gx/x" on a 6500 IOS box, you get a bunch of info on the queue of that particular port. At the bottom of the display are counters for dropped packets in the various queues for tx and rx as shown here:
Packets dropped on Transmit:
BPDU packets: 0
queue thresh dropped [cos-map]
---------------------------------------------------
1 1 629939 [0 1 ]
1 2 0 [2 3 ]
2 1 0 [4 6 ]
2 2 0* [7 ]
3 1 0* [5 ]
* - shared transmit counter
Packets dropped on Receive:
BPDU packets: 0
queue thresh dropped [cos-map]
---------------------------------------------------
1 1 310142 [0 1 2 3 4 5 6 7 ]
This output shows queue 1 threshold 1 has dropped 629939 packets on transmit, and 310142 packets dropped on the receive side.
Is there an SNMP mib that refers to the drop counters so that our network management platform can be alerted when drops occur?
