High CPU on Cisco 2960 caused by process HLFM address learning
Hi
I have been checking a switch for high CPU Util, below is the output of the processes. I added bpduguard to all the access ports which were missing looked like a BPDU flood, this did not fix the issue. It is a Cisco C2960. Any ideas guys on the fix. I rebooted the switch it cleared the process, is there anything else I can do other than rebooting the switch in the furure ?
