[c-nsp] ME3600 - ping drop seen

[Aaron Gould]

I have an ME3600 running 15.4(3)S3. and I saw a systematic drop on pings,
making me think there was some sort of built-in control plane protection.

 

(pinging the ME3600 from a remote device)

!!!!!!!!!!!.!!!!!.!!!!!!!!!!!.!!!!!!!!!!!.!!!!!!!!!!!.!!!!!!!!!!!.!!!!

!!!!!!!.!!!!!!!!!!!.!!!!!!!!!!!.!!!!!!!!!!!.!!!!!!!!!!!.

 

I downgraded it to 15.2(4)S5 and no longer see the drops.

Is there somewhere I could've seen these drops in a counter somewhere?  Or a
way to enable/disable that behavior?
