Can WLC's built-in DHCP provide IP addresses for wired client?

[robert.huang]

Hi,

We've got a WLC running on 7.0.98.0. It's providing IP addresses for the Guest Wireless users. Now we'd like to put a couple of wired workstations for those customers who don't bring laptops. I'm wondering if I put these workstations on the same guest wireless vlan, they can still get IPs from the WLC. If not, I have set static IPs on these workstations.

Thanks in advance.

Hi,

Yes, if you have a guest WLAN configured using the anchor and foreign setup, with the ANCHOR WLC as the DHCP server for the WLAN.

Rob:
The answer is simply "No". WLC can not provide wired clients on same wireless VLAN with IP addresses if the DHCP is configured on WLC.

The case metnioned by fbarboza above is a "very" special configuraiton on WLANs where the WLC is configured to take care of some wired clients and it needs you to have two WLCs  (The featured is called wired guest).This special case does not apply at your situation.

With your situation my answer above applies.

Note 
A internal DHCP server pool will only serve the wireless clients of that controller, not clients of other controllers. Also, internal DHCP server can only serve wireless clients and not wired clients.
