Just curious.
I'd have to dig out some old notes, but there was an informal discussion on some ISP mailing lists. With the RISC processors, 70% is about the highest 5-minute utilization you should see in routine use. Non-RISC processors are more like 50%. YMMV if you are doing especially processor-intensive things, especially if they are bursty in nature. This is generally pure IP, as you'd expect with ISPs. In the older days, I did some strange and wonderful things when the 7000 had great transfer rates but an underpowered CPU. One approach would be to get a 3-slot 7010 and put a CIP, an FDDI (then the only available 100 Mbps), and maybe a maintenance Ethernet into it. I'd use the FDDI to connect to 4500/4700 processors that did all the heavy-duty RSRB and the like, and bridge to the CIP chassis. At the edge of the network, four 2500s had more CPU power than a single 7000. -- "What Problem are you trying to solve?" ***send Cisco questions to the list, so all can benefit -- not directly to me*** ******************************************************************************** Howard C.
