Status of all people forgotten password forgotten password of the day but on the Cisco Catalyst series switches can be frustrating. With various Cisco router, you must switch on the Control Panel, but I think it will be a remote desktop control panel cable to the computer connected to a switch or physical proximity switches. However Frustrating part is a switch in order to switch boot into ROM, you need to switch on the body to pull it off and the front mode button press and hold the power plug it back.
This laboratory will discuss the reset and (or) clears the password for Cisco Catalyst LAN switches include, but are not limited to 2900XL 2950,3500XL, 3,550, 3,560 series switches.
For this reason forgot to switch password can be quite frustrating. As a CCNA certified network engineer, you need to know how to perform this procedure, and does not refer to any Cisco documentation.
Lab Objectives:
- By pressing and holding the mode button and switch the power switch inserted into ROM boot switch.
- Rename configuration in the Flash file to a different name, such as; config.old.
- Does the start switch and the Flash:config.old content to running configuration after you receive the privileged level of access.
- Runs the specified configure boot configuration will be updated through synchronization to copy the configuration to NVRAM.
Lab Instruction:
Step 1 . Start the exchanger to exchanger ROM by pressing and holding the mode button, in front of the switch and insert the power switch on the left side. Please note that different Exchange requires you to hold different amount of time mode button.
As shown in the following table indicate that you need to hold down the mode button, turn on the power switch; time after insertion.
Step 2 . Once you have successfully guided to switch ROM, you will see the following scheduling;
Boot Sector Filesystem (bs) installed, fsid: 2
Base ethernet MAC Address: 00:14:f2:d2:41:80
Xmodem file system is available.
The password-recovery mechanism is enabled.
The system has been interrupted prior to initializing the
flash filesystem. The following commands will initialize
the flash filesystem, and finish loading the operating
system software:
flash_init
boot
switch:
Step 3. Once your at the SWITCH ROM prompt you’ll need to initialize the flash by typing the flash_init command.
switch:flash_init
Initializing Flash...
flashfs[0]: 5 files, 1 directories
flashfs[0]: 0 orphaned files, 0 orphaned directories
flashfs[0]: Total bytes: 15998976
flashfs[0]: Bytes used: 12282368
flashfs[0]: Bytes available: 3716608
flashfs[0]: flashfs fsck took 10 seconds.
...done Initializing Flash.
switch:
Step 4. List the files stored in flash to view the avaliable configuration text files. By default the configuration file name is config.text;
switch:dir flash:
Directory of flash:/
1 -rwx 10573494 c3560-advipservicesk9-mz.122-44.SE6.bin
2 -rwx 684 vlan.dat
3 -rwx 1938 private-config.text
4 -rwx 1654 config.text
5 -rwx 3096 multiple-fs
3716608 bytes available (10508886 bytes used)
switch:
Step 5. You will see in the given config.text is 1654 bytes in the above example, this file renamed to config.old
If you just want to erase instead of reset password configuration you can use to remove the Flash:config.text command.
switch:rename flash:config.text flash:config.old
Step 6. Is config.text named config.old verifies that the document actually was renamed the correct dir Flash: command. Once you verify that the configuration file has been renamed from the boot command switch.
Step 7. Once the switch has started initial configuration settings for your system will prompt, ignore this user mode access.

Would you like to enter the initial configuration dialog? [yes/no]: n
Switch>
Step 8. If you don't want to reset the password in the description referred to in the 5th step, you can stop now. If you want to reset the password on the configured before proceed to step 9.
Step 9. Change to privileged mode and copy the contents of the old start-up configuration to the running config using the command copy flash:config.old run
Switch>enable
Switch#copy flash:config.old run
Destination filename [running-config]?
1654 bytes copied in 9.647 secs (171 bytes/sec)
ARSCORESW1#
Step 10. After you've loaded the old configuration file as a configuration of the round, you are in privileged mode, you will be able to change your password, enable secret password or line. Once you have changed the password for start command can be run by issuing copies to save the configuration.
Switch#configure terminal
Switch(config)#enable password NEWENABLEPASSWORD
Switch(config)#line con0
Switch(config-line)#password NEWCONSOLELINEPASSWORD
Switch(config-line)#end
Switch#copy run start
Destination filename [startup-config]?
Building configuration...
[OK]
0 bytes copied in 1.309 secs (0 bytes/sec)
