Extreme Switch CPU utilization on port-mirroring ?

Hi,

 

I have an extreme switch Summit 400-24p. I am running port-mirroring for two ports on tthe switch. I need to check what impact does it make on the CPU when i run port mirroring for a said number of ports?

 

The show version output is as follows:

-----------------------------------------------------------------------------------------------------

Extreme switch:32 # show version

System Serial Number: 
CPU board: 8S40524P3A1   P12236889  CP1: 4   CP2: 06
Image : Extremeware  Version 7.5e.2.8 [non-ssh] by Release_Master on 03/08/06 03:53:37

BootROM : 5.1

Also when i run "top" command the output is as follows:

Can some one point out how can i find cpu statistics on the extreme summit switch when we run port-mirroring ? And also how much load does port-mirroring make on the switch? Is there any forecasting or dimensioning done for this ?

 

regards,
