how to troubleshoot interface throttles on autonomous access points

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.


FastEthernet0 is up, line protocol is up
  Hardware is PowerPCElvis Ethernet, address is 001d.a1ed.5cda (bia 001d.a1ed.5cda)
  MTU 1500 bytes, BW 100000 Kbit, DLY 100 usec,

  Full-duplex, 100Mb/s, MII
  ARP type: ARPA, ARP Timeout 04:00:00
  Last input 00:00:00, output 00:00:00, output hang never
  Last clearing of "show interface" counters 00:56:08
  Input queue: 5/160/0/0 (size/max/drops/flushes); Total output drops: 0

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.
