[c-nsp] shaping outbound

[Dan Letkeman]

Ok, so my solution would look something like this:

class-map match-any application
 match protocol http

policy-map inbound
 class application
  police 10000000 1000000....
 class class-default
  police 20000000 2000000....

interface g0/1
 service-policy input inbound

And this would police http traffic to 10mbps and all other traffic to 20mbps.

Are there any recommendations on the police command to limit the about
of drops I get from doing this?

I do have an ASA5520 in front of this router, is there any way of
utilizing that to shape the traffic?

Thanks,
Dan.
