[L]et me assure you that the undocumented access level for the
LANplex/Corebuilder products are purely for support reasons then
anything else.  We have many cases where customers will forget their
passwords or userids and find themselves in a spot as they could not
get in to the console.  This is the only way we can help them to
recover from this situation without losing their entire
configuration.  [...]

Excuse me for being blunt, but: poppycock.  Pure spin-doctoring.  I can
think of at least two other ways right off the top of my head.

One would be to give the switches in question a physical setting (a
back-panel switch, a jumper on the pc board, whatever) that overrides
the password somehow - for example, causes any password to be accepted.
(Of course, one would not normally run with the hardware set this way.)

Another would be to keep the password information in a separate NVRAM
from the rest of the configuration, so that either can be reset without
having to touch the other.

Either of these would be an appropriate disaster-recovery mechanism.

A "secret" backdoor access mechanism is not.
