[e-nsp] Extreme Switch CPU utilization on port-mirroring ?

[Hamid Ahmed]

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

  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,
  HA
