Doubt in CSS memory allocation and CPU

Hi,

I have two CSS11503 and one is active (CSS1) and other is standby (CSS2). However when I made the command sh system-resources I have the following output:

CSS1# sh system-resources

System Resources for 1/1:

Installed Memory: 268,435,456 (256 MB)

Free Memory: 134,610,640 (128 MB)

CPU: 6%

CSS2# sh system-resources

System Resources for 1/1:

Installed Memory: 268,435,456 (256 MB)

Free Memory: 134,602,976 (128 MB)

CPU: 6%

The CSS1 is active and process all the traffic but the CPU and Memory used is the same in both CSS’s.

This behaviour is normal? How CSS alloc memory? In startup alloc a block of 128MB?

Regards

Re: Doubt in CSS memory allocation and CPU

when the css boots it automatically allocate memory for FCB. An FCB is a block of memory to store flow information.

So, this is normaly to see the same amount of memory being used on the 2 CSS.

Only if your active CSS requires more FCB will the CSS allocate more memory and you will then see a difference between active and standby.

Gilles.
