Downgrading a Stack to a Release Prior to FastIron 09.0.10a

Note: RUCKUS recommends that you establish a console connection with all stack units prior to the downgrade.

The major format change for stacking in the FastIron 09.0.10a is the inclusion of the ethernet keyword before port IDs (for example, stack-port ethernet 1/2/1) in the stack-port, stack-trunk, multi-stack-port, and multi-stack-trunk commands.

To downgrade to a release prior to FastIron 09.0.00 in the 08.0.9x format, copy the old startup-config file you saved previously back to the ICX device. The following example downgrades an ICX 7550 device by copying the file named saved_startup_08095 from the server at the specified IP address and saving it as startup-config.

ICX7550-48ZP Router# copy tftp startup-config 10.176.131.99 saved_startup_08095

If you have backed up the configuration and you use the correct saved startup-config file, the stack will remain intact. However, if the stack breaks for any reason, such as a power failure, use the recovery procedure (Recovering a Broken Stack After a Downgrade from FastIron 09.0.10a or Later) to re-establish the stack and stacking connections.
