At one of our customer location we got 4507 switch as access switch and 3750 switch as core switch. Its a very small network consist of

10-15 switches. This 4507 is new switch with 4 gigabit ethernet line cards and standby supervisor engine.  This switch is showing cpu load between 20 to 25%. We collected  cpu logs and Cat4k Mgmt HiPri / Cat4k Mgmt LoPri are only taking the cpu no other process taking much cpu.


There is no problem with my network but still i want to know if this is the normal behaviour of switch.


Is this the normal cpu load???????


I am attaching the output of show tech-suuport

Hello Sudhir,

there is a specific document that helps in troubleshooting high cpu usage on C4500



http://www.cisco.com/en/US/products/hw/switches/ps663/products_tech_note09186a00804cef15.shtml


also this process uses cpu


143        4340       704       6164  5.27%  3.70%  1.19%   0 HTTP CP


use sh proc cpu sorted 1min

   That is normal "low" cpu utilization for that model.  It would show 25-30%  with nothing attached to the switch as that is the normal cpu just to turn on the box and have it sit there doing it's normal function .
