About this task
Perform the following tasks so that in
the unlikely event of a failure or timeout, you can provide your router support
provider the information needed to troubleshoot the problem.
Procedure
-
Verify the current software
version.
-
Download the software package
from the Extreme website to a
server that is running the service for your chosen upgrade method.
-
Decompress the software archive.
-
Decide on a migration path if
you are crossing a known boundary, such as 32-bit to 64-bit, or kernel version
2.6 to 4.14.
- Check the connected
devices to ensure software compatibility.
- See the "SLX-OS Compatibility” section of the SLX-OS
Release Notes for the recommended software version.
-
If you will download software
from a file server, verify that the file server is reachable from the SLX device
and that you can transfer files from the server to the SLX device.
-
Back up your router
configuration to a remote server or a prepared USB device that is attached to
the SLX device.

Connect the SLX device to a
computer with a serial console cable.
Ensure that all serial consoles and any open network connection sessions, such
as Telnet, are logged and included with any trouble reports.
-
Run the copy support
command to collect all current core files to a remote server or USB 3.0 device
before downloading the software.
The collected information can
help you troubleshoot the software download process in the event of a problem.
After you troubleshoot the problem, you can use the clear support
command to remove the collected files.
