Change the Network Operating System Personality

Use this procedure on a VOSS switch to change the Network Operating System (NOS) personality.

The primary method to select a NOS personality for the switch is by using ExtremeCloud IQ. If the network is not accessible, or if you do not use Extreme Networks management software, you can change the NOS personality by using VOSS CLI commands.

Before you begin

Use FTP to transfer the NOS image to the /intflash/ directory in the VOSS file system.

About this task

If you change the NOS personality, the system deletes all configuration, licensing, and log files that pertain to the previous NOS personality.

If a power interruption occurs during a personality change, the system restarts the process after you restore power to the switch.

As part of the NOS personality change, you must restart the switch. If, during the restart, the system detects a failure, the NOS personality does not change. After the original NOS restarts, it logs an error message and raises a persistent alarm.

Note

Note

This procedure does not provide information about upgrading VOSS. For details about upgrading the VOSS release, see Upgrade the Software.

    Important

    If you decide not to change the NOS personality, before you restart the switch, you can run the software activate command again with the primary release as the image name and the system cancels the NOS personality change.

  6. Restart the switch.
