saved-configuration (filename)” command before rebooting to the old code. Then, after the
code has been downgraded, the device can be logged in from the console or by Telnet, but not
SSH. The SSH authentication details will need to be reset.
 If no backup configuration has been saved but it is still possible to access the device
management via some method while running the old code (e.g. Console, Telnet or SSH), then
you can redefine all the device management passwords as required.
 If after a downgrade it is impossible to login to the device via any method, then there are two
ways to recover the switch:
 From the BOOT menu, set the new code to run again and reboot the device. Disable Telnet
authentication:
User-interface vty 0 4
Authentication mode none
Then save the configuration and downgrade the code again, login via Telnet and reset all
the passwords as required.
 From the BOOT menu. On boot-up, use Ctrl+B to enter the Boot menu and then force the
unit to use the factory default configuration (bypassing the user configuration). The unit will
then need to be fully reconfigured.

 Workaround: Make sure the switches have similar card configurations, can back up each other,
and are rebooted at the same time. If the IRF fabric splits, reboot the smallest IRF system so the
switches can join the system to re-form a 4-chassis fabric.
