there are 6 processors in the CSM.
So when looking at the cpu, the command gives you all processors info.
There are 5 IXP, each one will show a percentage.
Then there 1 PPC, which always runs at 100% as the total is divided among all the processes.
Each process is given to you with a name and a percentage.
It is not really useful to monitor the ppc since it is always running at 100%.
However, you should watch your IXP's and make sure you have an everage below 50%.
