Feature licenses

This section describes the types of licenses and lists the features that require a license.
Software releases prior to Release 5.4 require no licenses. Switches and licenses are
purchased separately. The Avaya Ethernet Routing Switch 4000 series supports trial and
advanced license types.
To use the following features you must obtain the appropriate license:
• Open Shortest Path First (OSPF) (beginning with Release 5.4)
• Virtual Router Redundancy Protocol (VRRP) (beginning with Release 5.5)
• Equal Cost Multi Path (ECMP) (beginning with Release 5.6)
A trial license can be obtained to try out advanced license features for 30 days. Trial licenses
are obtained from Avaya and installed using the ACLI. After the trial period has expired the
licensed feature is disabled.
To minimize network and device impacts, the following events occur before the expiration of a
trial license:
• A system trap is sent five days before license expiration.
• A system trap is sent one day before license expiration.
• A system trap is sent at license expiration.
To fully enable advanced license features, a license kit must be purchased, a license file
generated, and the file installed on the switch. Each license kit contains a license certificate
and a License Authorization Code (LAC) for a specific number or level of licenses. The license
certificate contains the following instructions for license file generation:
• deposit LACs into an online license bank
• find and use the switch MAC address for license file generation
