# License file generation

This section describes what you must do after you purchase a License Kit.

After you purchase a License Kit, you must generate the license file on the Avaya licensing portal at http://www.avayadatalicensing.com. The Avaya licensing portal acts as a license bank—an electronic repository for all license entitlements and licenses.

The License Certificate in the License Kit contains the License Authorization Code (LAC). After you enter the LAC on the licensing portal, the system deposits license entitlements into your license bank. Then you can use one or more switch MAC addresses to generate a license file. Because the system generates the software license file based on the switch MAC address, the license file must contain the authorized MAC addresses of the switches where the license file is installed.

You can generate an individual license file with one or multiple switch MAC addresses and you can add MAC addresses to the same license file at a later time. One license file can support up to 1000 unique MAC addresses.

To support licensed features in a switch stack, ensure that you generate the license from the MAC address of the base unit.

To ensure that licensed features continue to operate if the Base Unit (BU) in a switch stack fails, Avaya recommends that you also enter the MAC address of the Temporary Base Unit (TBU), in addition to the MAC address of the BU, when you generate a license file for a stack of two or more switches.

You can purchase License Kits in combinations. For example, to enable licensed features for 22 MAC addresses, order one AL1016001 kit and one AL1016002 kit. The two kits provide licenses for a total of 22 MAC addresses.

The following table provides the License Kit order codes, license type descriptions, and number of licenses supported for each license kit.

Table 1. License kit order codes
Part number/order code | License type and description | Number of switches or MAC addresses supported
--- | --- | ---
AL1016001 | Avaya Ethernet Routing Switch 5000 Advanced License Kit, for 1 switch/stack. Enabled features: IPFIX, SMLT, OSPF, ECMP, VRRP and PIM-SM (one license required for each stack or standalone unit). | 1 switch/stack (2 MAC addresses)
AL1016002 | Avaya Ethernet Routing Switch 5000 Advanced License Kit, for up to 10 switches/stacks. Enabled features: IPFIX, SMLT, OSPF, ECMP, VRRP and PIM-SM (one license required for each stack or standalone unit). | 10 switches/stacks (20 MAC addresses)
AL1016003 | Avaya Ethernet Routing Switch 5000 Advanced License Kit, for up to 50 switches/stacks. Enabled features: IPFIX, SMLT, OSPF, ECMP, VRRP and PIM-SM (one license required for each stack or standalone unit). | 50 switches/stacks (100 MAC addresses)
AL1016004 | Avaya Ethernet Routing Switch 5000 Advanced License Kit, for up to 100 switches/stacks. Enabled features: IPFIX, SMLT, OSPF, ECMP, VRRP and PIM-SM (one license required for each stack or standalone unit). | 100 switches/stacks (200 MAC addresses)

After you receive the license file, to access licensed features, you must install the license file on the switch.
