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,
     reliability 255/255, txload 1/255, rxload 1/255
  Encapsulation 802.1Q Virtual LAN, Vlan ID  1., loopback not set
  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
  Queueing strategy: fifo
  Output queue: 0/40 (size/max)
  5 minute input rate 488000 bits/sec, 89 packets/sec
  5 minute output rate 114000 bits/sec, 82 packets/sec
     309489 packets input, 266454487 bytes
     Received 58203 broadcasts, 0 runts, 0 giants, 1665 throttles
     0 input errors, 0 CRC, 0 frame, 0 overrun, 1611 ignored
     0 watchdog
     0 input packets with dribble condition detected
     276111 packets output, 86012391 bytes, 0 underruns
     0 output errors, 0 collisions, 0 interface resets

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.
