Symptom
Unable to perform password recovery via console - despite entering BREAK, the unit boots into IOS-XE.
Conditions
This is seen on C9800-L appliance, with ROMMON 16.12(1r), and with confreg set to a value that does not allow console break, such as 0x2102.
Workaround
Before getting into this situation, reconfigure the unit with a config-register value that allows console break. For example:
unit#configure terminal
config-register 0x2002
end
unit#write mem
and/or you can download and install 16.12(3r) (or above) ROMMON.
If you are already locked out of the unit, and have lost your password, then recover the controller
via its reset button. This will erase the configuration.
Further Problem Description
ROMMON 16.12(1r) mistakenly interprets the 9800-L's default ROMMON value
(0x2102) as disabling break.
This is fixed in ROMMON 16.12(3r) and above.
