CPU usage on the VIP is related to the ingress packet rate, and the features needed to handle those packets. Once the ACLs are applied, the FIB lookup is completed, and the packet is dispatched to the egress interface, very little resources are consumed. VIPs handling your uplinks could "melt" under attack, since the uplinks can probably sustain enough PPS to exceed the VIP capabilities. pt _______________________________________________ cisco-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
