There is no known backdoor password for the Passport 1000 CPU
modules. In order to access a CPU when the password is not known, you must
factory default the box. For this reason, it is advisable to save the output
from "show config" and save it to a PCMCIA card or your computer. The "show
config" output will contain the passwords in plain-text format, and the
config information in this file can be input back to the CPU after a factory
default.
Connect to the console port on the 1297 or 1298 CPU module.
Reset the CPU.
Enter monitor mode.
Type: config sys set flags factorydefault true
Type: save config
Type: reset
Allow the CPU to completely boot to the banner login screen.
Login with the username 'rwa' and a password of 'rwa'
Type: config sys set flags factorydefault false
Type: save config
The Passport 1000 is now defaulted. If you have a previously saved
file with the output from "show config," you may re-enter your config
information from that file.
