Wes, The earlier policy doesn't use bandwidth commands, hence, it doesn't *subscribe* anything. The only thing it does is ensures that individual sites do not exceed their shaped rate. You could add bandwidth statements if you wanted to ensure a certain site always is guaranteed a certain amount of bandwidth from the parent shaper. You can't oversubscribe with the bandwidth command. policy-map parent_shaper class class-default shape average 100000000 service-policy site_shaper policy-map site_shaper class t1_site shape average 1536000 bandwidth percent 1 service-policy qos_global class multilink_site shape average 3072000 bandwidth percent 2 service-policy qos_global class class-default bandwidth percent 97 service-policy qos_global policy-map qos_global ! ... whatever you want here. This would make sure that large sites don't stare out small spoke sites for bandwidth. On Thu, May 9, 2013 at 8:58 AM, Wes Tribble <westribble () gmail com> wrote:
Thanks for the information Tyler, I will have to play around with that kind of policy in my lab. What would you suggest if you are oversubscribing the interface? With the child policy inheriting the bandwith of the parent shaper, wouldn't I run out of bandwidth allocation before I built all the shapers for all of my 29 sites?
