Can we do mac binding in cisco wlc controller

[ujoshi001]

HI ,

Can we do mac binding in any Cisco controller?

customer want to use DHCP server of cisco wlc controller and in that, they want to bind mac address with IP address.

every time if a client disconnects and reconnect, it should be picked the same IP which is bind.

please confirm, if any document is there for the same please share.

thanks

No you can not do mac to IP bindings with the WLC internal DHCP server:

The controller has the ability to provide internal DHCP server. This feature is very limited and considered as convenience that is often used simple demonstration or proof-of-concept, for example in a lab environment. The best practice is NOT to use this feature in an enterprise production network.

he internal DHCP server was introduced initially for branch offices where an external DHCP server is not available. It is designed to support a small wireless network with less than ten Access Points (APs) that are on the same subnet. The internal server provides IP addresses to wireless clients, direct-connect APs, appliance-mode APs on the management interface, and DHCP requests that are relayed from APs. It is not a full-blown general purpose DHCP server. It only supports limited functionality and will not scale in a larger deployment.

In order to do what your after your options are to use a DHCP server (Windows Server / DHCPD etc) or use the cisco switch/ router as the DHCP server

Do not use the WLC DHCP Server, that feature is removed from newer WLC models. Better use another DHCP server, like the router.
