Upgrade the Software

Important

Upgrades from some releases require release-specific steps. For more information, see Release Notes for VOSS.

Perform this procedure to upgrade the software on the switch. This procedure shows how to upgrade the software using the internal flash memory as the file storage location.

Use one of the following options to upload the file with the new software to the switch:

Use FTP or SFTP to transfer the file.
Download the image file to your computer. Copy the file to a USB device and insert the USB device into the USB port on the switch.

You can store up to six software releases on the switch. If you have six releases already stored on the switch, then you will be prompted to remove one release before you can proceed to add and activate a new software release.

For information about how to remove a software release, see Deleting a software release.

Before you begin

To obtain the new software, go to the Extreme Networks support site: http://www.extremenetworks.com/support. You need a valid user or site ID and password.
Back up the configuration files.
Use an FTP or SFTP application or USB device to transfer the file with the new software release to the switch.
Ensure that you have not configured a VLAN above 4059. If you have, you must port all configuration on this VLAN to another VLAN, before you begin the upgrade.

Caution

Only VLAN range 2 to 4059 is supported. All configuration on a higher numbered VLAN from earlier releases will be lost after the upgrade.
Check the MACsec configuration on the device prior to upgrading. For more information, see Important upgrade consideration regarding MACsec.

Note

Software upgrade configurations are case-sensitive.

Procedure

Enter Global Configuration mode:

enable

configure terminal
If you are using the USB port to transfer files, go to the next step. If you are using FTP or SFTP to download the files, start the FTP daemon on the switch and enable the ftpd flag for FTP or sshd flag for SFTP:

Note

Start an FTP session from your computer to the switch using the same username and password used to Telnet or SSH to the switch. Upload or copy the image to the switch.

boot config flag <ftpd | sshd>

end
Download the files to the switch through FTP or SFTP, or transfer them to the switch through the USB port.
Enter Privileged EXEC configuration mode by exiting the Global Configuration mode.

exit
Extract the release distribution files to the /intflash/release/ directory:

software add WORD<1-99>
Install the image:

software activate WORD<1-99>
Restart the switch:

reset

Important

After you restart the system, you have the amount of time configured for the commit timer to verify the upgrade and commit the software to gold. If you do not commit the software to gold and auto-commit is not enabled, the system restarts with the last known working version after the commit timer has expired. This feature ensures you can regain control of the system if an upgrade fails. By default, auto-commit is enabled.
After you restart the switch, enter Privileged EXEC configuration mode:

rwa

enable
Confirm the software is upgraded:

show software
Commit the software:

software commit

Important

If you disable the auto-commit feature, you must run the software commit command manually before the commit timer expires to commit the new software version, otherwise the system restarts automatically to the previous (committed) version. By default, auto-commit is enabled.

Example

Note

The image file name is switch dependent. See Release Notes for VOSS for information about file names.
