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

You can store only two software releases on 5420 Series and 5520 Series. If you attempt to add a third software release, you are promted for a confirmation to overwrite the non-primary release. You can also use the software add <filename> -y command to bypass the confirmation question and automatically overwrite the non-primary release.

Procedure

Enter Privileged EXEC mode:

enable
Unpack the NOS image:

software add WORD<1-99> -y

Note

The .voss file is removed after the software add command runs.
Install the NOS image:

software activate WORD<1-99>
Confirm you want to change the NOS personality by entering Y.
Confirm the new image has been added and will become active after the next restart:

show 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.
Restart the switch.

Example

Change the NOS personality to ExtremeXOS.
