Chapter 8 Troubleshooting Cisco 1800 Series Routers (Modular)
Recovering a Lost Password
The terminal should display one of the following prompts:
Router>
(indicates the user EXEC command mode)
or
Router#
(indicates the privileged EXEC command mode)
The Cisco IOS software checks the system condition once every 30 seconds. If a condition still exists,
the error message is displayed again; if the error condition has cleared, a recovery message is displayed.
Table 8-2
describes some of the most common system error and recovery messages.
Recovering a Lost Password
You can recover a lost enable password, but an enable secret password is encrypted and is not
recoverable. If you lose an enable secret password that is configured on your router, you can replace it
with a new enable secret password.
For password recovery and replacement procedures, see the
Password Recovery Procedures
.
