Dot11Radio interface is having increasing output drop

[Super-Man]

There was constant output drop on the Dot11Radio interface for the 3 AP. The below mentioned issue is output of AP.

AP-1#sh int do0 | i drop
Input queue: 0/1127/351/0 (size/max/drops/flushes); Total output drops: 1719738176

can you provide the useful instruction to troubleshoot problem?

The above mentioned issue could be happening because of Channel interference or Weak signal.

Well I am suggesting that you should run ‘sh dot11 assoc’ command. It will tell you about the client. again you will need to run the command but this time at the end of the MAC address of the client and look on Signal Strength. You will have the low negative number. Also post the output over here so that I can help you out.

Thanks a lot for helping out. Following is the output of the above mentioned command.

AP-1#sh dot11 associations all-client | i Strength
Signal Strength : -46 dBm Connected for : 1771 seconds
Signal Strength : -67 dBm Connected for : 14286 seconds
Signal Strength : -35 dBm Connected for : 50001 seconds

now help me out plzzzzzz......

After going through the output of yours I wanted to tell you that low number means that the channel is not busy or there is little interference. So far I am not aware of any other solutions but you can contact the Cisco technical support to get the further help on the above mentioned issue.
