Upgrading to the latest version of VSX

This chapter provides information about upgrading customer configurations to the latest version of the Virtual Switching Extension (VSX). The upgrade steps provided in this chapter support upgrades from the following configurations:

  • Configurations from ArubaOS-CX 10.01 and earlier version of 10.02: VSX synchronization is paused during the software upgrade.

  • Configurations that include the MCLAG feature operating on ArubaOS-CX 10.00: VSX provides advanced capabilities beyond what was previously available with the MCLAG feature. The configuration differences and equivalencies between MCLAG and VSX are provided later in this chapter.

    During the upgrade, the MCLAG configuration is removed and VSX must be configured through the CLI. The upgrade process does not automatically migrate the configurations that include MCLAG on ArubaOS-CX 10.00 to VSX in this release.


A maintenance window is required for this upgrade. Perform the upgrade with the assistance of support engineers for minimizing network downtime.
