Check out this thread http://puck.nether.net/pipermail/cisco-nsp/2007-May/040374.html I had a similar issue with a 3750, the cause was "redirected" traffic Even though ip redirects were disabled on the vlan interface they were being punted to the cpu and then dropped. Try a 3750E-Jenner#sh controller cpu-interface | i icmp icmp 1886230815 0 0 0 0 3750E-Jenner#sh controller cpu-interface | i icmp icmp 1886236301 0 0 0 0 3750E-Jenner#sh controller cpu-interface | i icmp icmp 1886239093 0 0 0 0 To see if thet are increasing. The only way I was able to resolve this was by moving the traffic so that it was routed between two seperate interfaces.

The first device you mentioned, is it running layer 2 only, into the L2 access switchport and then out to the L2 trunk? ________________________________________ From: [EMAIL PROTECTED] [EMAIL PROTECTED] On Behalf Of Mark Kent [EMAIL PROTECTED] Sent: Monday, January 21, 2008 10:31 PM To: cisco-nsp@puck.nether.net Subject: [c-nsp] cisco 3560 layer3 performance Hello, I've got a cisco 3560 (WS-C3560G-48TS-S) pulling in (80Mbs, 6500pps) on one switch port, and sending it out a trunk... cpu load is 5%. Another cisco 3560, pulling in that same traffic on a trunk and sending it out a layer3 point-to-point gigE is running at 70 to 80% (cpu hog is "IP Input"). In fact, the cpu load is roughly the same as the Mbs load. 50Mbs = 50%. Now, I know it's a small switch in the cisco line. But wouldn't we expect it to do a fair bit better than this? It looks like it will crap out at 100Mbs of layer3 traffic.
