# Defining reason codes for auxiliary

The auxiliary reason code describes the reason for changing your state to the AUX mode. You can use the auxiliary reason code only if you have defined the reason codes in the System Settings window.

Use the following steps to define the auxiliary reason codes and to associate them with the numeric reason codes supported in Avaya Aura® Communication Manager.

1. On the top bar, click System Options > System Settings.
2. In the left pane of the System Settings dialog box, click Reason Codes. This opens the Reason Codes panel on the right.
3. From the Select menu to edit list, select Aux Reason Codes. A default and untitled reason code item is displayed under a root node in the container below Select menu to edit list.

   You can add a singular auxiliary reason code or create a group and add a set of auxiliary reason codes in that group. Reason codes having similar or related characteristics are organized together in one group. Make sure that the labels given to the group are easy to understand the group activity.

4. To add a group, perform the following steps:
   1. Click the Add Reason Group button at the bottom of the Reason Codes panel. This adds an untitled group node in the container below Select menu to edit list.
   2. Select the untitled node and type the group name. The group node gets labeled with the name you type.
   3. Follow step 5 to add reason codes to the group.
5. To add a solitary reason code, perform the following steps:
   1. Select the node under which you want to add a reason code. This node may be the root node or a group node.
   2. Click the Add Reason Code button. This adds an untitled reason code item under the selected node.
   3. Select the untitled reason code item and rename it. The reason code name replaces the default name of the reason code item.
   4. Repeat step 5 to add as many singular reason codes you want to.
6. Click OK to save your settings.

   The system displays the newly created auxiliary reason code in the Auxiliary list of the Change Agent State drop-down list.
