We have a remote office with 5 APs. Our main office has 20APs and a 5500 WLC. At the remote office we simply plugged in the APs and added them to he same group as the other APs. Everything works fine. Regardless of what office you are in, if you join the wireless network you get an IP in that range and all is good.
So, at the remote office they have an existing vlan. Can I create a new wireless network that accesses that subnet if the subnet does not have an interface on the WLC?
Make sense? I am not sure if I am being clear or not.
You can... when using FlexConnect, local switching, the vlan at the remote site is mapped to the WLAN from the FlexConnect WLAN to VLAN mapping. You shouldn't create a dynamic interface on the WLC for that subnet as its not part of the subnet's the WLC is at. So what you need to so is on the WLAN that you want to use that remote subnet, you select FlexConnect local switching on the advanced tab. Then the AP's at that site, you need to convert them from local to FlexConnect. They will REBOOT!!!! Then after they come back online, you need to configure the AP's port from access to trunk allowing the vlan the AP resides on and the new subnet. The vlan the AP management is on, you need to set that up as the native vlan. Then on the AP, you need click on the FlexConnect tab, click vlan support and configure the native vlan and hit apply. Go bakc to the AP and click again on the FlexConnect tab and now click on Vlan Mapping... on there, you should see the WLAN that you enabled FlexConnect local switching and you would configure the vlan id and hit apply... that's basically it.
