Limit bandwidth usage on ASA Outside Interface

I had an interesting question posed to me today about how to limit bandwidth usage on the outside interface of an ASA device

I did some research, and this is what I came up with.   Limiting traffic to 2.5 Meg a second

class-map CM_BW_Throttle
match any


policy-map PM_BW_Throttle
class CM_BW_Throttle
police input 2500000
police output 2500000
exit
exit


service-policy PM_BW_Throttle Outside

                  

Will this interfere with the default inspections or other traffic?    I want to make sure it doesn't shut down traffic to the outside interface when it's applied.

No, it will not interfere with your default inspection and it will not shutdown the traffic to and from the outside interface.

It will merely apply policing so traffic is not exceeding 2.5Mbps.

Here is the command for your reference:
