Variables in Device Profiles

Create and use device profile variables just like you do elsewhere in the Mist portal: first you define {{key}}, value pairs in the device profile, and then you reference the key(s) in a WLAN template. In this way, variables make it easy to both scale the configuration and have AP-specific settings that vary according to the WLAN.

Variables are most commonly used in device profiles for WLAN fields including, SSID, passphrase, VLAN, radio bands and RADIUS Authentication / Accounting Server.

Syntax and Rules for Variables

  • {{variable}}, and {{guest2_VLAN_id1}}.

  • Except for underscores, don't use spaces or special characters.

  • Upper case is OK.

  • Numbers are OK.

  • Use double brackets {{variable}} to define the variable name.

Regarding precedence, variables configured directly on the APs are given the highest priority, followed by those configured in a device profile, and then those configured at the Site level.

You can also use the Mist API to view the actual configuration that is being applied, for example, as a way to see exactly which variable is being used: https://api.mist.com/api/v1/docs/Home.
