Cisco AP Detailed Client Info

Trying to figure out what some of these mean… You can use show dot11 assoc to find clients associated to the AP then you can use show dot11 assoc xxxx.xxxx.xxxx to show detailed information for a specific client or even use ‘all-clients’ to show all clients detailed information that are associated to the Access Point. Here’s the output from show dot11 all-clients

I need to find out what “Capability : WMM ShortHdr ShortSlot 11h” means and available options. These clients are connecting at lower speeds when they do not have “WMM” in the Capability column.
