Be extremely cautious before using command modes intended for TAC or
developer use. It's bad enough that the ex-Stratacom switches have
privileged mode commands, accessible to users, that can screw up
NVRAM/EPROM to the point that boards have to be returned for factory
service. I can't say that this is the case for L2/L3 switches, but
I'd be very careful unless I was _certain_ I knew all the effects of
a command.
Certain IOS commands, at least, were never really documented in Cisco
outside the IOS code or code specifications. TAC would bring in a
developer, or some senior support person with code access, to use
them in the rare appropriate situations.
If you are having this strange a problem, isn't it time to call TAC
and file a problem report?
