Description:

In a Public Spot scenario, it may be desirable to create different Public Spot SSIDs for different user groups (e.g. normal and premium).

For Public Spot vouchers to be created using the Setup Wizard, a separate administrator needs to be created for each SSID.

This article describes how to use a “Circuit ID” to control which SSID a Public Spot user can connect to.

Info
The Circuit ID identifies the interface used by a terminal (e.g. a notebook) to issue a DHCP request.

Requirements:

LCOS as of version 9.10 (download latest version)
LANtools as of version 9.10 (download latest version)
Any web browser (for access using WEBconfig)
SSH client for command-line access (e.g. PuTTY)
Installed and functional Public Spot
Installed and functional WLAN controller (in a WLAN controller scenario)

Configuration:

1) Check that the Public Spot SSID is assigned to the logical WLAN interface:

1.1) Connect to the web interface of the access point using a web browser and navigate to the path LCOS menu tree → Status → WLAN → Networks.

1.2) Check which logical interface (Ifc) the Public Spot SSIDs (Network Name) are assigned to.

Info
You can also view the information using the CLI command ls Status/WLAN/Networks/.

2) Setting the Circuit ID under DHCP snooping:

2.1) Open the configuration for the access point in LANconfig and switch to the menu item Interfaces → Snooping → DHCP snooping.

2.2) Select the logical WLAN interface (see step 1.2) and adjust the following parameters.

Set a checkmark next to Add agent info.
For Circuit ID, set the variable %s.

Info
The variable %s inserts the WLAN SSID if the DHCP packet originates from a WLAN client.

Hinweis

In a WLAN controller scenario, these settings must also be set on the access points. These settings can be rolled out to the access points using a script and the WLAN controller.

The sample script installs the settings for the logical interfaces WLAN-1, WLAN-1-2, WLAN-2 and WLAN-2-2. Adjust the script according to your needs if necessary.

3) Add the called-station attribute in the Public Spot:

3.1) Connect to the web interface of the Public Spot gateway using a web browser and navigate to the path LCOS menu tree → Setup → Public-Spot-Module → RADIUS-Servers.

3.2) Edit the entry and save the following parameters:

Auth.-Attribute-Values: Called-Station-Id=%{BF-Agent-Circuit-ID}
Acc.-Attribute-Values: Called-Station-Id=%{BF-Agent-Circuit-ID}

4) Create two administrators who can create new Public Spot users:

4.1) Open the configuration for the Public Spot gateway in LANconfig and switch to the menu item Management → Admin → Further administrators.

4.2) Create two new entries and modify the following parameters:

Administrator: Enter a descriptive name.
Password: Set a password for the administrator.
Access rights: From the drop-down menu, select None.
Function rights: Remove all of the functions except Public Spot wizard (add user) and Public Spot wizard (manage user).

5) Assign the Circuit ID for the Public Spot administrator:

Each Public Spot administrator is able to create vouchers for a certain Public Spot SSID.

5.1) Connect to the web interface of the Public Spot gateway using a web browser and navigate to the path LCOS menu tree → Setup → Public-Spot-Module → Circuit-IDs.

5.2) Create two new entries and set the following parameters:

Administrator: Enter the Public Spot administrators created in step 4.
Circuit-Id: Enter the associated Public Spot SSID (see step 1.2).
