======Adding Operator-Name======

Cisco ISE doesn't insert O-N into the Request by default. O-N helps Home sites identify where their users' authentications are coming from. Combined with Chargeable User Identity, Home and Visited sites can provide and follow an audit trail back to a user without the Visited site knowing the users' details.

=====Adding the Operator-Name attribute=====

  * Go to **Policy** -> **Policy Elements** -> **Dictionaries**.
  * Open up the **System** dropdown.
  * Open up the **Radius** dropdown.
  * Click on **IETF**.
  * Click on **unknown-126** and enter
    * **Attribute Name** as 'Operator-Name'
    * **Data Type** as STRING
    * **Direction** as IN
  * Click **Save**
