High CPU utilization in 6513 core switches

Hello,

we have two 6513 core switches redundant to each other by using HSRP and MST. Currently we have a problem in a CPU as it's high in both cores as appeared in the following logging message:

1: 04/09/12 16:06:20    7/-1: MAJ, GOLD,

High CPU utilization in 6513 core switches

Hello Heba,

The CPU is high because of Interrupt. You might want to check this page for guidance:

http://www.cisco.com/en/US/products/hw/switches/ps708/products_tech_note09186a00804916e0.shtml#situations

Also, this document which teaches you how to capture traffic going to CPU:

Hope this helps,
