Does anyone know what the "channel Fame Fragmentation Rate" is?

 Users are getting randomly disconnected, I came across these stastics when I went to check on the retry and error rate.

 

The best I can guess is that it is an IP fragmentation issue, but what would cause this? As far as I can tell, the MTU looks fine.

That number does not automatically explain disconnections.  Something else must be going on.  How long have you had this wireless network?

Good question! I have been getting this information third-hand, and getting details like that has been proving difficult.

 

 I will be gathering more information by doing some debugging on the clients and doing a "show ap client trail-info", but I was just puzzled by that percentage, and it bothered me that I didn't know what it meant.

I would obtain the logs.tar first.  That would say alot about the environment.

 Yep, I already have the tar logs. I am not concerned with this being a cause of their issue. I am just curious to know what the channel fragmentation rate is, and what it means.

It just reports on what percentage of the traffic on the channel is a fragment.  On the channel could be on that access point or another access point that is not even in your WLAN.
