That's why I wrote "with SUPs" (and not RSPs). RSP is fairly new, and they got it right this time.

I'm trying to keep all Cisco equipment idle, if at all possible, since there may come worse times... Typical exceptions are - software forwarding routers, where CPU load is directly depending on current traffic levels; should the load stay above 15-20% all the time, it's time for an upgrade - slow-CPU boxes like everything Cisco with SUPs, since the CPU load _always_ jumps to 100% for short periods of time - BGP needs something calculated ;-) I get interested whenever CPU load _stays_ high - switches; Cisco switches need like 5% CPU to blink the LEDs ;) It gets more interested with packet filters and load balancers, where CPU loads depend on traffic levels and patterns. I try to keep the baseline between 5 and 10%. HTH, Elmar.
Network equipments process utilization
Hi everyone, I wonder which percentage is good level of CPU and Memory util of network equipment ? In my case, I try to keep under 30% cpu util and 70% memory util. My most equipment are Cisco product. I have no technical reference about that, it is just a rule of mine or my predecessor. Could you tell me how other operators are doing ? what is your operation baseline ? or is there any guideline about process utilization ?
