License generation
After purchasing a license kit, a license file must be generated on the licensing portal. This
licensing portal acts as a license bank to store all license entitlements and licenses.
The license certificate found in the license kit contains a License Authorization Code (LAC).
This LAC is submitted to the license portal, which deposits license entitlements into a license
bank. This license entitlement is combined with the switch MAC address to generate a license
file. Because license files are generated based on a switch MAC address, the license file must
contain the authorized MAC addresses of the switches where it will be installed.
A license can contain multiple MAC addresses and MAC addresses can be added to the
license file at a later time. A single license file can support more than one MAC address. The
number of MAC addresses supported is dependent on the type of license. To support licensed
features in a stack, use the MAC address of the Base Unit.
The following table provides information on the license kits available for the Avaya Ethernet
Routing Switch 4000:
Part Number
License Type Number of Switches / MAC
Addresses Supported
AL4516001 ERS4500 Adv License 1
AL4516002 ERS4500 Adv License 10
Generating a license file
About this task
This section contains the procedure for license file generation. Ensure the following
prerequisites are met before generating a license:
• Purchase a license kit
• Ensure a properly configured TFTP server is reachable from the switch or stack on, which
the license file will be installed.
• Obtain the switch base MAC addresses for the switches that use licensed features.
• Ensure the default web browser does not automatically decompress the files.
