ROM Monitor Program Version 12.1(10r)EY(1.21)
Board type 1, Board revision 7
Swamp FPGA revision 16, Dagobah FPGA revision 43
Timer interrupt test passed.
MAC Address : 00-02-b9-83-af-fe
IP Address : 172.16.84.122
Netmask : 255.255.255.0
Gateway : 172.16.84.1
TftpServer : Not set.
Main Memory : 256 MBytes
***** The system will autoboot in 5 seconds *****
Type control-C to prevent autobooting.
!--- At this point, press Ctrl-C.
Autoboot cancelled......... please wait!!!
Autoboot cancelled......... please wait!!!
rommon 1 > [interrupt]
!--- The mole ended in the ROMmon.
rommon 1 > [interrupt]
Issue the confreg command at the rommon prompt.
Make the selections that appear here in boldface for password recovery:
rommon 1 > set
rommon 1 > confreg
Configuration Summary :
=> load ROM after netboot fails
=> console baud: 9600
=> autoboot from: commands specified in 'BOOT' environment variable
do you wish to change the configuration? y/n [n]: y
enable "diagnostic mode"? y/n [n]: n
enable "use net in IP bcast address"? y/n [n]: n
disable "load ROM after netboot fails"? y/n [n]: n
enable "use all zero broadcast"? y/n [n]: n
enable "break/abort has effect"? y/n [n]: n
enable "ignore system config info"? y/n [n]: y
change console baud rate? y/n [n]: n
change the boot characteristics? y/n [n]: n
Configuration Summary :
=> load ROM after netboot fails
=> ignore system config info
=> console baud: 9600
=> autoboot from: commands specified in 'BOOT' environment variable
do you wish to save this configuration? y/n [n]: y
You must reset or power cycle for new configuration to take effect
Note: You can also use the confreg 0x2142 command at the ROMmon prompt in order to set the configuration register value to bypass the startup configuration stored in NVRAM.
rommon 1 >confreg 0x2142
You must reset or power cycle for the new configuration to take effect.
Issue the reset command so that the mole reboots.
Due to the changes that you made in step 2, the mole reboots but ignores the saved configuration.
rommon 2 > reset

Make sure that the configuration register value is 0x2142.
This value makes the mole boot from Flash without a load of the saved configuration. Issue the enable command at the Switch prompt to go to enable mode. Then, issue the show version command to check the configuration register value.

Issue the configure memory command or the copy startup-config running-config command to copy the NVRAM into memory.
Do not issue the configure terminal command, which shows the default configuration on the mole.

Issue the show ip interface brief command to make sure that the interfaces that were in use earlier show an "up up" status.
If any of the interfaces that were in use before the password recovery show "down", issue the no shutdown command on that interface to bring the interface up.
Issue the write terminal command or the show running-config command to display the saved configuration on the mole.

Now you are ready to change the password on the mole.
Issue these commands to change the password:
c-4006-SUPIII#configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
c-4006-SUPIII(config)#no enable secret
!--- This step is necessary if the switch had an enable
!--- secret password.
c-4006-SUPIII(config)#enable secret < password >
[Choose a strong password with at least one capital letter,
one number, and one special character.]
!--- This command sets the new password.
Make sure that you change the configuration register value back to 0x2102.
Complete these steps at the config prompt to change and verify the configuration register value.
c-4006-SUPIII(config)#config-register 0x2102
c-4006-SUPIII(config)# ^Z
