# How to configure DN link auto-configuration

#### **DN link auto-configuration**

Once that distribution nodes are installed, use the DN link auto-configuration feature to automatically configure wireless links between distribution nodes.

Prerequisites:

- During physical installation, the installer should note the MAC address and hostname of each device, along with the location and direction that the device is facing.
- The hostname and MAC address of the device are listed as **HN:** and **MA:** on the device label and contained in the QR code on the label, as shown in [Required network design information](https://support.altowav.com/altoplex-network-design-and-deployment-guidelines-d423.html?hsLang=en-us).
- DHCP should be enabled on the backhaul network.

**DN link auto-configuration process flowchart**

To auto-configure DN links:

1. Access the WebUI of the first DN. In your browser's address bar, type:
   
   **https://*hostname***
   
   where *hostname* is the hostname (KB-XX-XX-XX) or IP address of the radio. See [Connecting to the AltoPlex radio](https://support.altowav.com/connect-to-the-altoreach-device.html#h3) for more information.

     1. Click the **login** link in the WebUI header to log in as administrator. The default password is **admin**.

     2. On the **Wireless** tab, in the **Configuration** section, leave the **Radio 0 DN responder** field blank.
     3. In the **DN link auto-configuration** section, type the MAC address of the **DN responder**.
     4. Click **Add**.
        
        ![](https://support.altowav.com/hs-fs/hubfs/kb-images/altoplex-radios/DN-link-autoconfig_D621_f04cd8e1.png?width=608&height=530&name=DN-link-autoconfig_D621_f04cd8e1.png)
     5. Perform other configuration as desired. See [Configuration via the WebUI](https://support.altowav.com/network-tab.html?hsLang=en-us).
2. Once the airlink between the DN initiator and DN responder is established, the responder will be automatically configured to include: 
     - The MAC address of the initiator for the **DN responder**.
     - The **channel** and **Golay index** being used by the initiator.
     - The opposite **polarity** of the initiator.
3. Access the WebUI for the DN responder (Node B in the above diagram). 
   
   Once the link between the initiator and the responder has been established, a link to the DN responder will appear in the **Peer-Name** column of the **Wireless Status** table.
   
   ![](https://support.altowav.com/hs-fs/hubfs/kb-images/altoplex-radios/DN-link-autoconfig_D621_1_99a32431.png?width=618&height=471&name=DN-link-autoconfig_D621_1_99a32431.png)
   
   Click the link to open the DN responder's WebUI. The **Status** page is displayed.
   
   If the switch connecting Node B and Node C is an unmanaged switch, or if it is a managed switch that is configured to forward LLDP data units, the hostname of Node C will be listed in the **LL Discovery** field.
   
   ![](https://support.altowav.com/hs-fs/hubfs/kb-images/altoplex-radios/DN-link-autoconfig_D423_2_4d417178.png?width=626&height=586&name=DN-link-autoconfig_D423_2_4d417178.png)
4. Access the WebUI for the next DN initiator (Node C in the above diagram). 
     1. Click the link in the **LL Discovery** field of Node B's WebUI. This will open the WebUI for Node C.
        
        If there is no link in the LL Discovery field, your switch may not be properly forwarding LLDP data units. In this case, access Node C's WebUI by using its hostname or IP address (**https://\<hostname\>/**).
     2. Click the **Wireless** tab.
     3. In the **Configuration** section, leave the **DN responder** field blank.
     4. In the **DN link auto-configuration** section, type the MAC address of the **DN responder**.
     5. Click **Add**.
     6. Perform other configuration as desired. See [Configuration via the WebUI](https://support.altowav.com/network-tab.html?hsLang=en-us).
5. Once the airlink is established, the DN responder will be auto-configured as described in step 2.
6. Continue this process for all of the distribution nodes in your system.

After the link between both distribution nodes has been established, perform [additional configuration](https://support.altowav.com/network-tab.html?hsLang=en-us) as necessary.

### Delete the DN responder from the DN link auto-configuration

To delete the DN responder from the DN link auto-configuration, click **Delete**.

You can only delete a DN responder from the DN link auto-configuration prior to the DN responder responding to the incoming link request from the DN initiator. Once the link has been established, the **Delete** button will have no effect.
