# Installing a license file using ACLI

## Before you begin

- Store the license on a TFTP server.

- Ensure that you have the correct license file—the license file contains the MAC address of the switch where you are installing the license.

- Ensure that your browser does not automatically decompress the compressed binary license file.

- Enable Autosave or save the current configuration to flash memory.

## About this task

Use this procedure to use ACLI to install a license file on a switch.

| Important
| If you reset the switch to default, you must reinstall the license file on the switch, and restart the switch, to reactivate the licensed features. The reset removes the software license from the switch because the system stores the license file in nonvolatile random access memory (NVRAM).

## Procedure

1. 1 Use the following command from Privileged EXEC mode: .

   `copy tftp license <A.B.C.D> <WORD>`

2. Restart the switch.

   | Important
   | Avaya recommends that you schedule switch restart during a normal maintenance window.
