Cisco Wireless Controller Address Assignments

[ifoam]

For descriptive purposes, lets assme I have 3 sites. Each site uses different subnets, say, 192.168.1.x, 192.168.2.x, 192.168.3.x.

Each site has 5 access points and all sites share the same SSID.

Is is possible to setup the controller to give out IP's based on where the client is trying to connect? For instance, a client connected at .1.x should receive .1.20 using the same SSID as when it would connect to .2.x and receive a .2.20 address.

Is this possible or do all clients using an SSID need to get an address in the same subnet?

If it is possible, how can I do this? Any links to cisco's site?

Hi,

Yes, you can assign DHCP like any other site in your Network. In my opinion, it's best to use a DHCP Server. The DHCP Server is specified on the Controller and sent via a unicast after the client is associated and passes auth. What version of the WLC are you running? I can send a link from the Cisco site.

4.2 i believe--the newest one.

Well, it might be a little more complicated than I explained.

site one has a dhcp server via windows 2003 server. site two has the same but for the second subnet

so, an AP at the first site has an ip of .1.240 and an ap of site 2 has an ip of .2.240

By default, will clients associating to the site 2 ap receive a .2.x address? and clients associating to the site 1 ap receive a .1.x address from their respective dhcp servers?

Hi,

If you have DHCP configured properly, the answer is yes. I would make sure you have the IP Helper configured on the Switch and that your WLC have the correct IP.
