[c-nsp] monitoring switch stacks

[Dale W. Carder]

Hey Ge!

We monitor for input queue drops on 6500's with this oid:

.1.3.6.1.4.1.9.9.276.1.1.1.1.10

Our alert for the NOC is drops > 100/sec results in a
major alarm.  Usually it's something stupid happening on
a given vlan that needs to be beat down.  For SVI's, this
goes hand in hand with punts causing cpu exhaustion on
these wimpy RP's.

I've thought about watching output queue drops, but am not
sure how to how to differentiate normal from abnormal.
