From the last few days a weird problem of drops is coming on NPE-G2 after the implementation of rate limit, policing or shaping. Everytime a policty is implemented on sub-interface,physical interface or on tunnel a pattern drops start. The total traffic on G2 router is approx 1 Mb. Even the case was raised to ciso TAC and consequence they are saying there might be issue with the IOS. But I have changed the ios many times but in vein. Anyone is facing this type of issue please update us so that we can male some plan of action to resolve it.
I am still working on it and update soon with some affirmative results.
