# Generating a license

## Before you begin

- Purchase a License Kit containing a License Certificate with a License Authorization code (LAC). For more information, contact your Avaya sales representative.

- Ensure that a properly configured TFTP server resides in your network.

- Assign IP addresses to all switches.

- Obtain the switch base MAC addresses for the switches that use licensed features—perform ACLI command `show sys-info` to obtain base MAC addresses.

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

- After you create the license file at the site identified in the License Kit, you must specify a file name; example: building100_ers5000.lic.

License file names must conform to the following restrictions:

- maximum of 63 alphanumeric characters

- lower case only

- no spaces or special characters permitted

- underscore (_) permitted

- doc (.) and a three character file extension required

If you need to include multiple MAC addresses in a license file, use a text-based file that conforms to the following rules:

- ASCII file format

- one MAC address on a line

- no other characters, spaces, or special characters permitted

- MAC addresses in hexadecimal, capitalized format, each pair of characters separated by colons: example, (XX:XX:XX:XX:XX:XX)

- file must contain correct MAC addresses—incorrect MAC addresses result in licensed features not working on designated units

- number of MAC addresses must not exceed the number of MAC addresses allowed for the LAC entered for a file as described in the following table:
