Hi,
For hwXQoSBufferUsageSlotStatTable I found OID 1.3.6.1.4.1.2011.5.25.32.4.1.4.5.1.1
$ snmpwalk -c public -v 2c A.B.C.D .1.3.6.1.4.1.2011.5.25.32.4.1.4.5.1.1

Slot : 1
Total : 45370 cells (9215 KBytes)
Current used : 42 cells (8 KBytes)
Remained : 45328 cells (9207 KBytes)
Peak used : 30235 cells (6141 KBytes)
Average used : 10 cells (2 KBytes)
Looks like last number is average used buffer in kilobytes., so this is exactly what I search.
Thanks.
