CISCO PASSWORD RECOVERY PROCEDURES

Phase 1:

Hook everything up and have Hyperterminal configured and running:

Hook up DB9 to RJ45 Adapter with rollover cable to serial port of PC and Console port of router

Set up Hyperterminal to (9600-8-N-1) (defaults to 2400-8-N-1)

Phase 2:

Turn on Router

Within 60 seconds, Press CTRL Break (pause break key on keyboard)

The router should bypass NVRAM and go into Bootrom mode

(it will look like this >)

At that prompt, type in o/r 0x2142 (this resets the configuration register to ignore NVRAM on startup)

Then, press I (for initialization or setup)

Answer NO for the initial setup question

Phase 3:

You are now at the console...

The prompt should look like this:

Router>

Type in ENABLE

It will change to this:

Router#

Start entering commands

Phase 4:

Enter Configuration mode:

At the privileged mode (enable), type in CONFIG T

(ALMOST ALL commands are done in this mode)

To set up passwords:

CONFIG T

ENABLE SECRET secret (where the first secret is the enable mode, and the second “secret” is the password)

LINE CON 0

PASSWORD password (where the first password is the viewing password and the second “password” is the actual password)

LOGIN (forces you to login in order to even view anything)

CTRL Z to exit

Phase 5:

IMPORTANT STEP:

At the config t stage, type in :

CONFIG-REGISTER 0x2102 (this sets it up so that it will load the startup-config file from the NVRAM on next reboot of the router)

Do a SHOW VER to confirm the register setting to 0x2102

THEN, copy running configuration to startup configuration:

COPY RUN START

Then restart the router:

RELOAD
