Cisco ASA 9.1 - Possible to police individual flows within a set bandwidth cap?
Posted on 2014-11-18
In this scenario, there is a 10Mb pipe out of the ASA to ISP1. The goal is to police inbound/outbound traffic to inside subnet X.X.X.X/24 to use a max of 8Mb of that pipe. This I've accomplished with a service policy on the ISP1 interface, with the observed behaviour being that download 1 will take up all 8Mb, then when a second download starts, they will begin to share the 8Mb, then a third starts and again they will all share the pipe evenly, so the aggregate of the flows continues to use a max of 8Mb. But I'm trying to determine if there's a way to police the individual flows in the subnet. Meaning "hey you subnet X, flows to/from IPs in your range can only use up to 5Mb each, with your aggregate total being 8Mb".
