guideline,the safe value of CPU, Memory and free-ports in a switch

[Seok-Bin Lim]

Hello,

does anyone who knows what the guideline value for above mentioned in any Cisco Switches?

If anyone knows, May I know where it is in Cisco site or some other place?

I am making a Cisco network proposal documents.

can not difficult to find out the threshold values cuz in general, thoes values are given by customers.

Thanks a lot in advance.

Hello,

there are no specific  thresholds defined for CPU, mem, ... for any devices. The only thing  that can be done is check CPU or mem utilization on a specific router  and verify whether it is normal/expected for the configuration used,  amount of routes/prefixes, ...

Regards,

Fred

Hi

I’ve searched for this type of information so many times, and I think it’s weird that there are no guidelines for these things. It should be possible to specify some threshold where things would start going wrong. If a networking device is at 100% CPU utilisation 24 hours a day there would be some problems since everything wouldn’t get done. So less than 100% all the time is good. Working backwards from there it should be possible to get to a point where most things will work as it should. A rule like: “More than X percent for the 5 minute average over two consecutive intervals” could then be created in a NMS.

How do we go about requesting such a metric guide from Cisco?
