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 thenetwork is not accessible, or if you do not use Extreme Networks management software, you canchange 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 thatpertain 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.
Procedure
1. Enter Privileged EXEC mode:
enable2. Unpack the NOS image:software add WORD<1-99>
3. Install the NOS image:software activate WORD<1-99>
4. Confirm you want to change the NOS personality by entering Y.
5. 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 nameand the system cancels the NOS personality change.
6. Restart the switch.
