Clearing the Router: The Reset and Clear Buttons in Combination
The combination of the Reset and Clear buttons restores all factory
defaults, including configuration defaults. It also removes the manager
and user passwords. You might want to use this procedure (as described
below), for example, in situations such as the following:
So many settings in the configuration need to be changed that it
would be easier to start over with the factory defaults.
You want to redeploy the router somewhere else using a different
configuration.
The configuration has become so corrupted that you cannot access
the router from the console.
The Reset-Clear combination erases the changes made to the router
configuration and restores the default (factory) configuration values.
This means that bridging (without spanning tree), but not routing, is
then enabled on all ports.
The Reset and Clear buttons are recessed. To press each button, use a
non-conducting pointed implement like a wooden pencil or a toothpick.
