That depends on what kind of policer you use. There are three different types on a Sup720: per-interface, aggregate and microflow. The first is completely "per interface" and no amount of traffic flooding on one interface would affect the other interfaces even when using the same policy-map. Aggregate (or "named") policers are shared among all ports on which you apply them. Microflow policers police each flow separately. I think there's something special about egress policing though I can't remember what at the moment. Take a look at this for details: http://www.cisco.com/en/US/products/hw/switches/ps700/products_tech_note09186a00801c8c4b.shtml -- Peter _______________________________________________ cisco-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
