Question : Cisco 4006 High CPU Usage
|
|
Recently I had noticed that several functions on the network paused for a second or two and then started up again. After looking into it I found that our 4006 (which we are using as a core) has the CPU running at 99%. We are running 12.1(11br)EW code. We have 4 vlans with ACL's on three of them.
After doing some research I found that if I do a sh proc cpu the main user is
Cat 4k Mgmt LoPro with a 5 sec of 79.15% and 5 min of 77.78%
If I do a show platform health it shows that
KxAclPathMan create/ is using 31% on 5 sec and 5 min is 34%
and
K2FibAdjMan Host Mov is using 26% on 5 min.
I figured this was an ACL issue so just for kicks I took down all of my ACL's for a few minutes and the CPU usage did not change at all.
This switch is probably 3/5 of the way loaded. Not doing too much except for routing vlans.
I realize this is an old switch but I should be able to squeeze a little more life out of it.
