i know these things are eol and i'm gonna ask for replacements in july but any insight on what would keep this thing constantly high (and the highest process is the status indicator - i think).

C3500XL Software (C3500XL-C3H2S-M), Version 12.0(5)WC10

and i cycled the power but no difference.

I have this problem too.

I think this is normal on the c3500xl switches.

If u are using psvt on the switches every spanning-tree instance uses some cpu to handle spanning-tree updates ( BPDU etc..)

Image u have 40 vlan .. the switch needs to do this for every vlan. Eats up some cpu.

Cpu load doens't say anything about the fowarding of packets since it's done in hardware. So there is no direct relation between cpu load and the nummer of traffic that is passing the swithces.

We have 2900xl's in an old netwerk with 50+ vlan they have 60+ cpu load constandly and having no problems with it.
