I have two stacked 3750s running PowerPC405. These are the switches we use for the Cisco Call Manager system. From 8am to 8pm they average about 64 % CPU utilization. We are getting ready to get into peak season and our call volume could increase another 50 % in the next weeks.
I would say that 70-80% of the traffic is local to the stack, so I dont think there is much I can do there, and its all L2 traffic. What is the next step up after the 3750 for a rack switch? What will give me 3-5 years of life if my traffic patterns increase annually at about 20-30%.
Or perhaps I dont need to worry at all. Can switches like the 3750 run fine at 70 %??
Thanks for all advice and help,
