For the first time I'm receiving WAN connectivity via a FastEthernet hand off from the ISP's Router (26xx) at my premise.
I'm used to dealing with WAN circuits terminating directly on my router (1841). I'm also used to measuring the load on my circuit by viewing the tx and rx load from the "sh int s0/0" output.
Does the fact that i'm using a FastEthernet handoff render the tx and rx load section of the "sh int f0/0" command useless?

It also works but the load is normally really low or actually 1/255
My suggestion is to keep the load-interval (interval for load calculation for an interface) in something like 30 sec and then monitor the
30 second input rate 0 bits/sec, 0 packets/sec
30 second output rate 0 bits/sec, 0 packets/sec
Look at the rates and make your own baseline or normal traffic rates

You will still see the utilization as a value over 255 (255 = total capacity, 128 = half, 64=25%, etc.); no real difference at all.

I wouldn't think so. The tx and rx load measurements are the measurements of data that's going through the particular interface. It shouldn't matter what type of interface it is. Is there a particular problem that you're seeing?

Yes exactly, i'm only see 1's or 2's even thoug the circuit connected to the ISP's 26xx is fully utilized.
Should I change the bandwidth statement on my outside fastethernet interface to 1536 to reflect the actual speed of the upstream circuit? Would it more acurately show the load on the link?

Yes it would (I believe).

i also believe bandwidth statement is relative to the rxload / txload calculation.

"Does the fact that i'm using a FastEthernet handoff render the tx and rx load section of the "sh int f0/0" command useless?"
Not, I believe, if the interface's bandwidth statement reflects the actual WAN bandwidth.
