Reveal "****" passwords on Nortel switch?

[lwurl2]

I've come into possession of a network where the previous admin was lacking in documentation. In this, I have been trying to figure out what his existing SNMP strings were, along with the RADIUS key. (I have all the keys, but I don't know which were used on what devices.)

Is there a way to make the switch undo the password masking?

THANKS!

Some older ones can be un-hashed using tools off the internet.
