I am facing high CPU on one of my 4507R-E Chassis. I am having "WS-X45-SUP6-E" SUP and all of my line cards are "WS-X4648-RJ45V-E".
My current IOS is : 12.2(54)SG1
I have followed the below document.
http://www.cisco.com/c/en/us/support/docs/switches/catalyst-4000-series-switches/65591-cat4500-high-cpu.html
Till the time I have not run any CPU SPAN nor I have taken the debug outputs which I cannot do due to sensitivity of application running over the servers terminated over that switch to avoid any millisecond downtime.
I am pasting the rest of the output. Please suggest what can be the possible cause as we are not using DAI, DHCP Snooping or IGMP.
Please suggest if someone can suggest in this regard
