# Static Links⁣⁣⁣⁣⁣

In the "Static Links" section it is possible to set restrictions on the connections at the radio and pseudo-radio interfaces of the configured node. When the interface is set to static authorization mode (see [Link Settings](/astra-wireless-documentation/technical-documentation/astrawireless-evolution-technical-user-manual/operation-and-administration/basic-settings/link-settings.md)), connections will be established only with the nodes specified in this section, despite the wireless connection parameters and access key match. The parameters are:

* "*MAC"* -  MAC address of the neighbor unit
* "*Key"* - link security key (up to 64 characters long, without spaces).

Another two options are available:

* Disable the link by marking the option “*Disabled*" in the corresponding checkbox. This setting works also in public authorization mode (see [Link Settings](/astra-wireless-documentation/technical-documentation/astrawireless-evolution-technical-user-manual/operation-and-administration/basic-settings/link-settings.md)).
* Add a link description in the “*Note*" field

By clicking the «**Add**» button, you create a new fixed link to the unit.

By clicking the «**Remove**» button, you can delete an already created fixed link.
