# Profile Custom RADIUS Attributes

**Custom RADIUS attributes** send extra settings to the router for every user of a profile, for features that have no field in the profile form. Edit the profile and click **Custom Radius Attributes** at the top of the form.

## Adding an attribute

Fill in the empty last row and click the save icon:

<table id="bkmrk-fielddescription-att"><thead><tr><th>Field</th><th>Description</th></tr></thead><tbody><tr><td>Attribute</td><td>The RADIUS attribute name, exactly as in the router's dictionary (case-sensitive), for example <code>Mikrotik&#45;Group</code>.</td></tr><tr><td>Value</td><td>The value to send.</td></tr><tr><td>NAS Type</td><td>**any**, or only for one router type (Mikrotik, Cisco, Huawei…). It must match the Type set on the NAS.</td></tr><tr><td>Enabled</td><td>Untick to stop sending it without deleting it.</td></tr></tbody></table>

Attributes are sent when the user connects. Online users get them after reconnecting.

## Examples

<table id="bkmrk-attributevalueuse-mi"><thead><tr><th>Attribute</th><th>Value</th><th>Use</th></tr></thead><tbody><tr><td>Mikrotik-Group</td><td>isp2</td><td>For PPPoE, selects the MikroTik PPP profile with this name (its pool, DNS, routing). Useful to split packages over two uplinks.</td></tr><tr><td>Mikrotik-Address-List</td><td>vip</td><td>Adds users to a MikroTik address list.</td></tr><tr><td>Vendor attributes (Huawei, Cisco…)</td><td>as required by the BNG</td><td>Some BNGs need vendor-specific attributes for speed or services instead of the standard rate fields.</td></tr></tbody></table>

## Profile or user?

Attributes can also be set for a single user (user details page → **RADIUS** tab, system administrators). Set an attribute on the profile when it applies to everyone on the package, and on the user only for exceptions.

<p class="callout warning">Never set the **same attribute** on both the profile and the user. The router may receive both values and pick either one.</p>
