I am working on some byte counting stuff, and have a odd question.

I noticed on my of my routers:

     2403558863 packets input, 2476827328 bytes

thats:

     2,403,558,863 packets input, 
     2,476,827,328 bytes


which when divided out, comes to 1.03 bytes per packet, which without
saying is obviously in error.

So, when does a Cisco counter 'flip' ? How many bits is it?
