Switch Memory Utilization

Hi

what is the standard range for memory utilization on 35xx switches.

I know under minimal load they can be around 50% but what would be classed as a problem?

Most of mine are between 60% - 90% is this normal?

thanks

Re: Switch Memory Utilization

Hi,

With 3500xl's, the load minimum with 50% is OK.If I were you, I would have tried setting up the SPAN on switch and tried capture the traffic passing over the switch.

Link for SPAN config: http://www.cisco.com/univercd/cc/td/doc/product/lan/c2900xl/29_35wc5/scg/swports.htm#xtocid25

If the CPU utilization is more than 50% and there is no unusal traffic on the LAN, you might be hitting CSCdv21552.

Please refer the link below:

Re: Switch Memory Utilization

Thanks for the info.

I have spanned a couple of devices but nothing erroneous seems to be going on.

My main concern is if the switches are hitting 90% on memory utilization constantly, should I be looking at a better alternative

i.e replacing my old 3500XL's for 3550's ?

thanks
