Scheduled activation and deactivation of WLAN modules or SSIDs on managed LANCOM access points by means of a WLAN controller


Description:
Some scenarios require broadcast SSIDs or even the entire WLAN to be switched off at certain times.

This article describes how, in a WLC-managed WLAN scenario, you can schedule the activation and deactivation of the wireless modules or the broadcast SSIDs of managed access points.
    Info:
    How you disable WLAN modules or SSIDs on individual access points or WLAN routers (without WLC) is explained in the following Knowledge Base article: Database 'SP Knowledgebase', View '03. Edit Documents\by Responsible, Status', Document 'Enabling and disabling the WLAN or individual SSIDs according to the time on sigle acces points or WLAN routers'




Requirements:
  • LCOS as of version 9 (download latest version)
  • LANtools as of version 9 (download latest version)
  • Functioning WLC scenario



Procedure:

1) Scheduled (de)activation of WLAN modules of managed access points:

Info:
The procedures described below only works with access points that have their WLAN modules in “managed” mode and thus managed by a LANCOM WLAN controller.

In this example, the two WLAN modules of a WLC-managed LANCOM 1702B access point are deactivated at 19:00 and activated at 07:00.


1.1) Open the configuration for the WLC in LANconfig and switch to the menu item Date & time -> CRON table.

1.2) Create one entry to activate and one entry to deactivate the first WLAN module:
  • In the hours and minutes fields you specify the times for switching on and switching off.
  • In the Commands field you enter the command to switch off and switch on, respectively. Use the following syntax:
    Switch off:

    set /Setup/WLAN-Management/AP-Configuration/Accesspoints/<LAN-MAC address of the AP> {WLAN-Module-1} Off

    Switch on:

    set /Setup/WLAN-Management/AP-Configuration/Accesspoints/<LAN-MAC address of the AP> {WLAN-Module-1} <VALUE>

    Possible values for the WLAN modules are: Default, 2.4GHz, 5GHz, Off, Auto



Examples:
  • Switch off WLAN module 1:
    set /Setup/WLAN-Management/AP-Configuration/Accesspoints/00a057112233 {WLAN-Module-1} Off
  • Switch on WLAN module 1:
    set /Setup/WLAN-Management/AP-Configuration/Accesspoints/00a057112233 {WLAN-Module-1} default

1.3) For the scheduled activation and deactivation of the second WLAN module of the access point you have to repeat the process and create two cron table entries.

When specifying the WLAN module, you now replace {WLAN-Module-1} with {WLAN-Module-2}.




2) Scheduled (de)activation of an SSID broadcast from a managed AP:

In this example, the SSID “GUESTS” broadcast by a WLAN module of a WLC-managed LANCOM 1702B access point is deactivated at 19:00 and activated at 07:00.

2.1) Open the configuration for the WLC in LANconfig and switch to the menu item Date & time -> CRON table.

2.2) Create one entry to activate and one entry to deactivate the SSID “GUESTS”:
  • In the hours and minutes fields you specify the times for switching on and switching off.
  • In the Commands field you enter the command to switch off and switch on, respectively. Use the following syntax:
    Switch off:

    set /Setup/WLAN-Management/AP-Configuration/Networkprofiles/<SSID-Name> {Operating} No

    Switch on:

    set /Setup/WLAN-Management/AP-Configuration/Networkprofiles/<SSID-Name> {Operating} Yes



Examples:
  • Switch off SSID “GUESTS”:
    set /Setup/WLAN-Management/AP-Configuration/Networkprofiles/GUESTS {Operating} No
  • Switch on SSID “GUESTS”:
    set /Setup/WLAN-Management/AP-Configuration/Networkprofiles/GUESTS {Operating} Yes
