Deploying multiple WLANs at a remote site

Unanswered Question
Feb 28th, 2008

At Site-A where the WLC4200 & DHCP server reside, we have the following subnets:

- (vlan10) 10.10.10.0

- (vlan11) 10.10.11.0

Each VLAN corresponds to a dynamic interface on the WLC ("Int-10" & "Int-11") which is assigned to their own respective WLAN. Works fine.

At remote Site-B where we have a 1242 (HREAP), we have the following subnets:

(vlan100) 10.20.14.0

(vlan101) 10.20.15.0

If I want to assign vlan100 & vlan101 to their own respective local WLANs, will I need to create vlans 100 & 101 (define subnets 20.14 & 20.15 on my Site-A layer-3 switch) at Site-A?

I ultimately want to create 2 WLANs at the remote site, one for voice (w/ QOS enabled) and one for data. The problem I keep running into is, the remote wireless clients authenticate but are unable to get a DHCP address.

I have this problem too.

You need not create sepearate VLANs 100 and 101 on the site-A. Make sure the DHCP server is reachable. Ensure that IP helper pointing to your DHCP server is configured on the router at the remote site so that DHCP broadcast is from your client is forwarded to DHCP server. Refer http://www.cisco.com/en/US/docs/wireless/controller/4.0/configuration/guide/c40hreap.html for more information.
