The no form of the command removes this flow policer from actions on flows matching this AQP entry.
The no form of the command removes this flow policer from actions on flows matching this AQP entry.
The redirect only takes effect if the matching flows are HTTP and the condition specified after the http-redirect command, admitted flows or dropped-flows, is met. The condition specified by “dropped-flows” means the flow is dropped due to an AQP actions such as “flow rate/count policers” or “drop” actions. HTTP Policy Redirect on admitted-flows allows the operator to redirect HTTP traffic to a web portal while allowing non-HTTP matching the same AQP rule to be forwarded.
