High CPU Utilization for 'Cat4k Mgmt LoPri' process

Asked by: shahul537

Please help me in reducing the utilization of cpu for 'Cat4k Mgmt LoPri' process in Cisco 4503 switch. we have got 5 similar switches in other floors having the same problem. CPU utilization is more than 90% and it even reaches 98% most of the time. All these switches are being used as an access switch. Rest of our 65 access (4500 series) switches are fine. thanx in adv.

 Cisco says enabling ipx and appletalk routing can cause Cat4k Mgmt LoPri using high CPU. Check htis link http://cisco.com/en/US/products/hw/switches/ps663/products_tech_note09186a008014741c.shtml.
This protocols are process switched and add burden on the CPU.
