Looking to see if 4500X switch could be limiting bandwdth.

Hello, in our environment we have a hard bandwidth cap of 800mbps. The problem is that we are all new to the team and no one seems to know where this would have been put in place. I see one potential setting in our Firepower, but as we have two Cisco 4500X's as our core routers, I'm wondering if 7 where a policy may hide in the 4500's that may have the same impact?

BTW, you would be interested in the policing sections of @marce1000 provided reference.

So I did that, but wasn't able to come up with anything.  Any other places a QOS of traffic/bandwidth affecting policy could live on the switch?

The 4500x interfaces are all 1/10. So, try something like this:

show qos event all

or

show qos interface tenGigabitEthernet x/x 

if they are configued as VSS, than the interface should be x/x/x (1/1/1) or 2/1/1
