Hi Nick, > They do process, but only when IP routing is not enabled on the switch. Ah, right! It processes them when acting as a host. Makes sense :) Thanks! Sander signature.asc Description: Message signed with OpenPGP using GPGMail ___ cisco-nsp

They do process, but only when IP routing is not enabled on the switch. -Original Message- From: cisco-nsp [mailto:cisco-nsp-boun...@puck.nether.net] On Behalf Of Sander Steffann Sent: 08 March 2016 08:53 To: Chuck Church Cc: Cisco Mailing list Subject: Re: [c-nsp] C3560X Layer 3

Hi All, Quick update, It turns out that redirects were getting punted up to the CPU even with "no ip redirects" in the config. Split up the ranges on to 2 separate VLANs and the CPU dropped to 10% with 0% interupts. Thanks for your help. Regards David On 17/02/2016 03:55, Adam Baxter

Re: [c-nsp] C3560X Layer 3 throughput

Looks normal to me. your interrupt is only 6% ~ . they sit around 50%~ CPU. It will not cause any problems. This is of my 3750x Switches. CPU utilization for five seconds: 54%/4%; one minute: 48%; five minutes: 47% Take a look at the following.
