Please note that the DHCP option 12 (Hostname) only has effect when clients re-DHCP. So if you enabled that on a running network, it may take some time before all clients have reconnected to the network. Clients with static IP won't show up.
If you have an external authentication server (ClearPass for example) and authenticate the clients, you can return the IETF:User-Name with the name of the client/user and that would show up in the list instead of the mac address (or username).

Subject: Missing client IP addresses and names
Hi there. After updating my controllers to 8.10.0.9 about 6 months ago I've had an issue with the displaying of client information. Previously when I looked at the client list it would display all the IP addresses from my guest network, voice network and user networks. It also resolved most of the MAC addresses to the device names. SInce the update I'm only getting reliable IP info for the guest network and maybe a quarter of my user network and no voice stuff at all.
I searched this forum and found a suggestion to turn on DHCP option 12 in each Virtual AP setting to help resolve names. That helped a bit but hasn't fixed it completely. I'm also clueless as to why most of the IP's don't show up. I'm not clear on how the system actually reads this information to pass it to the controller in case it's a config thing on the switches or routers that I need to add. I have some areas still working as expected and others do not with no common factor that I can see. Does anyone have any ideas?
