High CPU stack switch 2960x

Hi everyone

 

The last months I have received claims about slow performance of application of users, I checked the switches and detected an strange behavior of CPU, always over 40%.

The CPU load is doing load-balancing? There is a process that always generate load and the interface output drops increase.

Some can help me about how works the CPU of members stack and the cause about drops.

Swtich 2960x , 4 members stack

That CPU value is not high.  Especially for a 2960X.

I also think its not high for C2960..

About "Hulc LED process" , you can refer to this blog as below.

show  interface error counter, 
also the broadcast and multicast is high in this interface ? check the STP status.

Hello,

 

one other thing you could try is to administratively shut down all unused ports on the stack switches, that sometimes helps bring CPU utilization down...
