Well for any of you that care our facility just upgraded to an 8600 core, the previous core was a stack of 5500 series switches. The cutover went great we moved all up-link edge closets over and most all servers also. We were having a serous problem with a 5530 in the core stack, it was just rebooting. After replacing the unit, trying new cables, new software, etc. the problem was still happening. I have the 'old' core stack running independently from our network, I'm going to do my best to make the problem re-occur. I really would like to know what the problem is, I'll keep you posted if we do find out what the issue is.
Anywho, on the 5500's I have a command I use frequently: show cpu-utilization. I know on the 8600 I can use: show sys perf. But it only shows the current stats, I like the 5500's output because it shows the last 24 hours. Anyone know the correct syntax I'm missing? Thanks in advance.
