Hello All, I am getting a 90% (at times 100%) on my 6509 switch. What could be the problem?

Most likely spanning-tree, but you can do a

"sh proc cpu | excl 0.00% 0.00% 0.00%"

to see which processes are driving the CPU.

Hi,

Most likely STP problem, routing loop, DDOS.

Post "show process CPU" "show process MEM" and also "show version"
