Mesh Point to Point link with 1520 AP's problems

[robporzig]

Hi All,

I'm trying to setup a PtP bridge link with two 1522 Mesh AP's and have had lots of difficulties getting this to work.

We have existing Mesh in another location connected to the same controller i'm using to manage the AP's for the bridge link. (So i know the Mesh controller works!)

Has anyone done this?

I have configured the near end AP (RAP with Ethernet bridging) and its joined the controller successfully. However the far end (MAP with bridging) joins the controller (i see it associate in the controller logs and comes up in Wireless --> AP detail) but then disconnects as it doesn't see a join confirmation from the controller. (taken form debugs on CLI of AP).

Any ideas or tips on this? Essentially all i'm trying to do is extend several VLANs across the bridge link to a switch on the other side hanging off the far end AP.

Any help is much appreciated!

Cheers - Rob

Just some more info on this one - this is basically what i have done:

(Running 4.1.197.. code)

> DHCP for AP is from a Windows server - Option 43 enabled.

> Primed both AP's so they joined controllers, set same bridge group name and same channel for 802.11a back-haul radio.

> set close end AP as Rap and enabled bridging.

> set far end AP as Map and enabled bridging.

> rebooted far end AP and connected to test switch as 'far end switch' (as it will now talk over the backhaul)

I assume the ports connected to the ethernet port on both AP's need to be trunked?

Hello Rob,

Mesh Point to Point link with 1520 AP's problems

Before adding a mesh access point to a network, do the following:

Step 1       Add the MAC address of the mesh access point to the controller’s MAC filter. See the Adding MAC Addresses of Mesh Access Points to MAC Filter section.
Step 2       Define the role (RAP or MAP) for the mesh access point. See the Defining Mesh Access Point Role section.
Step 3       Verify that Layer 3 is configured on the controller. See the Verifying Layer 3 Configuration section.
Step 4       Configure a primary, secondary, and tertiary controller for each mesh access point. See the Configuring Multiple Controllers Using DHCP 43 and DHCP 60 section.
Configure a backup controller. See the Configuring Backup Controllers section.
Step 5       Configure external authentication of MAC addresses using an external RADIUS server. See the Configuring External Authentication and Authorization Using a RADIUS Server.
Step 6       Configure global mesh parameters. See the Configuring Global Mesh Parameters section.
Step 7       Configure backhaul client access. See the Configuring Advanced Features section.
Step 8       Configure local mesh parameters. See the Configuring Local Mesh Parameters section.
Step 9       Configure antenna parameters. See the Configuring Antenna Gain section.
Step 10       Configure channels for serial backhaul. This step is applicable only to serial backhaul access points. See the Backhaul Channel Deselection on Serial Backhaul Access Point section.
Step 11       Configure the DCA channels for the mesh access points. See the Configuring Dynamic Channel Assignment section.
Step 12       Configure mobility groups (if desired) and assign controllers. See the Configuring Mobility Groups chapter in the Cisco Wireless LAN Controller Configuration Guide.
Step 13       Configure Ethernet bridging (if desired). See the Configuring Ethernet Bridging section.
Step 14       Configure advanced features such as Ethernet VLAN tagging network, video, and voice. See the Configuring Advanced Features section.
