I was looking at the following formula which I have seen
mentioned many times for WAN links:

        max(inOct,outOct) *8 *100/ifSpeed

What does this mean?   Are we taking the highest value
of the two and thresholding on it?    If someone could
explain a bit more than the standard "you need to
accomodate the fact that WAN links are Full Duplex" I would
really appreciate it..   I want to collect and threshold
Utilisation on Cisco serial  WAN interfaces, but the concerns
I have with the above formula are:-

        1. How do I put it into mibExpr.conf?
        2. What is the above formula trying to do?  I looks like it is
            taking the larger of the two and performing a util
            calculation using it and the "ifSpeed" interface value.
