IP Input as always is responsible for processing traffic that hardware/CEF isn't capable of processing. 'HL3U bkgrd' is actually managing a bunch of things (hardware ARP throttling, proxy ARP, ICMP redirect, TTL ICMP error generation, etc). So, I really suspect You did change switches but in meantime Your network also changed traffic characteristics and that's why You see the change in load. -- "I am a part of everything that I have | Łukasz Bromirski read." -- Theodore Roosevelt | http://lukasz.bromirski.net _______________________________________________ cisco-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
