[c-nsp] 3560 cpu load question

[Cord MacLeod]

My graphs show cpu spikes up to 20% every now and again, but the  
following command shows 100% spikes.  Question being is this normal  
behavior, how would I track the cause (assuming my traffic is  
relatively stable throughout the day) and should I be worried this may  
be impacting traffic?
