Description:

This document describes how to establish a point-to-point (P2P) connection between two LANCOM access points that are managed in the LANCOM Management Cloud (LMC).


Requirements:

The procedures described below are based on a fully functional network scenario managed by the LMC.


Scenario:

An LMC project contains numerous LANCOM access points, two of which must now communicate via a Wi-Fi point-to-point link due to a change of premises. All of the devices are already fully integrated into the LMC.

In this example, the access points of the type LN-1702B and LN-860 (see figure in the configuration step) are initially connected by Ethernet cable to a LANCOM switch, but the LANCOM LN-1702B is being moved so that it has to be connected to the rest of the local network exclusively via P2P link.

The LN-1702B is configured as a “slave” device for this purpose.

Please note that you must remove the LAN cable from the LN-1702B (the “slave” device) after completing the configuration, otherwise an endless network loop will occur!


Procedure:

To configure P2P links in the LMC, LANCOM Systems provides appropriate add-ins that need to be activated in the LMC project.

More useful add-in scripts are available in the online documentation for the add-ins.

1) In the Add-ins menu, click the Variables button.

2) Create a new variable with the name Master. All other configuration items remain unchanged.

3) Click on Save.

4) Create another new variable with the name Slave. Here, too, all other configuration items remain unchanged.

5) Click on Save.

6) The two new variables should then be listed in the variable list as follows:

7) Switch to the device dialog for the master device (here the LN-860) under Devices → LN-860 and switch to the Variables tab.

8) Click Add variables.

9) Use the checkbox to select the system variable Master.

10) In the “New value” column, add the value "true" for the "Master" variable. Then click on Add.

11) Switch to the device dialog for the slave device (here the LN -1702B) under Devices → LN-1702B and switch to the Variables tab.

12) Click Add variables.

13) Use the checkbox to select the system variable Slave.

14) In the “New value” column, add the value "true" for the "Slave" variable. Then click on Add.

15) Switch to the Networks menu and select the local network where you want to create the point-to-point link between the selected access points.

  • The access points must be located in this network.
  • The add-in may only be used for networks that are configured with “VLAN - untagged”. An add-in that allows the dynamic learning of the VLAN-ID is not yet available.

16) On the Add-ins tab, add the script “P2P-Master” and the script “P2P-Slave”.

17) Click the Save button.

18) The final step is to roll out the configuration changes to your network.

19) Mark all of the devices with a configuration marked as “Outdated” and then click Configuration roll out.

20) After rolling out the configuration, it is vital that you remove the Ethernet cable from the slave device!

21) The P2P connection is established now.
