Connecting Branch Office AP to HQ WLAN Controller

Hello Experts,

I have two remote sites and two of those sites connected back to HQ over L3 Fiber connection.
Remote sites have Distribution switch and inter vlan traffic is routed locally and default route is pointing to HQ office.
I have Aruba Controller at HQ and I want to remote site access points to this controller.

I will highly appreciate if someone what design and configuration is applicable to achieve the above requirement.

Do you mean you want to setup a VPN between sites? Sorry I do not understand the question. more information?

Hi,
Let me elaborate more.

I have Aruba WLAN controller at the main office and I want to connect the branch office Access Points with Main Office's controller.
I want to create an SSID at the controller for Branch Office users.
Main and Branch Office are connected over the Fiber with L3 links.

Of course, used Aruba before really good devices.

You want to setup a mesh network across different sites.

I am not really sure if this is possible to be honest.

Also do not really see the point of doing it, if you just set the SSID as the same in each site with the same auth details will that not work to the same effect?

Mesh is only really effective in the same office right?

Hi,
My concern is not to connect the sites, they are already connected.
I want to register branch office access points to main office controller. I need help on this point

I understand, not sure if it possible.

I also said it seems pointless as they are seperate offices.

Usually the mesh operates between wireless connections only right? and you are out of range....

You need to configure DHCP option 43 to tell the APs the IP address of the controller.  That's all there is to it.

http://www.arubanetworks.com/techdocs/ArubaOS_64_Web_Help/Content/ArubaFrameStyles/AP_Config/AP_discovery_ADP.htm

If you want to allow wireless clients to connect to the local network instead of having all traffic tunelled to the WLC you need to configure SSID and APs in bridge mode.  I can't tell you how to get the config done though as I haven't touched Aruba in years :-(

Hi Craigbeck,
Happy new year
I was able to successfully register the access points at branch office with the controller at main office.
Branch office can see the wireless SSID however post to associating the clients not recieving DHCP. Also I configure the static IP on the client but not able reach any network local and remote.

Attached is the design. Am I missing anything.

Hi cciedreamer,

Happy new year to you too!

Do you have the APs in bridge mode?  If so the port where the AP connects needs to be a trunk with the AP management and client VLANs allowed.  The AP management VLAN should be native.

Hi Thanks for your repky
Do I have to set the bridge mode under Vlan profile or AP profile ?
0
Craig BeckCommented:
You don't have to use bridge mode, unless you want client traffic to be switched at the local site.  If you don't use bridge mode it works just like Cisco where all traffic gets tunelled back the WLC.  You need to configure bridge mode on the SSID and the AP if you want to use it.

I want to keep local traffic at branch office.

Did you configure a virtual AP and set the client VLAN?
0
cciedreamerAuthor Commented:
Yes, I have configured the VAP and assigned client VLAN
But this VLAN exists at Branch Office not at the HQ.

Craig BeckCommented:
I understand.  This is why you need to bridge.  If you don't use a VAP and bridge the SSID it will tunnel to HQ, so you need it to assign a VLAN tag at the AP and drop onto the local switch.

If the SSID is configured in bridge mode and you have assigned a VLAN to the SSID it should work.  If you configure the VAP in bridge mode and assign the SSID to the VAP it will bridge.  Can you screenshot your config, please?

Hi Sir,
Sorry for the delayed in response. I did as you mentioned and its working successfully.

If so the port where the AP connects needs to be a trunk with the AP management and client VLANs allowed.  The AP management VLAN should be native.

Thanks for your usual support
