We have a Catalyst 3560G 24 port POE switch. It's been running fine for 1+ years. A few weeks ago we enabled SPAN on it to capture packets. Today, we had a random spike in CPU on the switch. Seems hardware swithing continued to work fine, but software based processes choked and effectively took down EIGRP, HSRP, etc. We collect syslogs from the router and we saw 2 crashes/reboots. Both showed the exact same error both times, with the same hex values. I **believe** the CPU usage dropped when a tech disconneted the SPAN port and it's state changed to down, but I'm not 100% sure.
Could this indicate an IOS bug (I'm hoping it's not a hardware failure)? And, can anyone track this down to see if this could be related to SPAN? I've disabled SPAN for now. Thank you.
