Dear All,
We're running a reasonably simple network consisting of 20 branch offices each hanging between 2-4 autonomous ap's (mainly 1131, some 1602's).
I see bursts of throttles and drops on FastEthernet0 on all ap's.
I will appreciate any advice/suggestions for how to troubleshoot this.

Post the output to the command "sh interface F0".

see sh int f0 above

I don't see any issues with the output. No line errors. No output drops. No duplex errors.
Looks good.
Note: I tend to ignore the "ignored" counters. Your AP is operating as autonomous so I'm suspecting they are just VTP packets in transit.
