Licensing

The Cisco Nexus 3550-F (formerly ExaLINK Fusion) has several features that can be unlocked by adding a license. This license is installed onto the device at the factory prior to shipping.

NoteFirmware versions from 1.7.0 to 1.14.0 have a "support date" requirement. A valid license with end-of-support date after the indicated date was required to install these firmware versions.

This requirement has been removed as of 1.15.0.

Please contact support if you need to roll back to a version earlier than 1.15.0 and your device did not ship with a suitable license with "support date" included.
