DEFAULT ROUTE IS CONFIGURED ON ACCESS SWITCH TOWARDS CORE SWITCHES.

I HAVE CONFIGURED THE STORM CONTROL UNICAST , MULTICAST, BROADCAST  LEVEL 65 - 87 ON TRUNK PORT IN & OUT. INTERFACE LIKE ACCESS TO CORE TRUNK LINK ONLY.

Hello! Good morning, 

To check the counters and the outputs of the storm control, please use the next commands:

Use the show interface typeX/X capabilities command to determine the mode in which storm control is supported on an interface.

Use the show interfaces counters storm-control command to display a count of discarded packets.

You can also use the command show storm-control. In that output “current” represents the percentage of traffic suppressed at a given instant, and the value is N/A for ports that perform suppression in hardware.

Hello

Start with a higher level and monitor the interfaces over a certain amount of time and then you should get a good baseline as to whats is a good level to sustain you network without diminishing connectivity.

sh storm control xxxx (unicast/broadcast/mulitcast)

Note : Broadcast and multicast are in situate when both enabled at the same time, Meaning if ether or both of their define levels are exceeded traffic will be blocked.
