4. Change config-register to ignore startup-config (NVRAM).
>o/r 0x2142 Then initialize with >i | 4. Change config register to ignore startup-config (NVRAM).
>confreg 0x2142 >reset | 4. Since these devices write their config automatically you should only need to test your passwords. |
5. Press Ctrl+C to break out of setup mode. | 5. Follow Steps 5–9 for the 2000, 2500, 3000, 4000, and 7000 to the left. | |
6. From enable mode, type copy start run but do not exit. (Old command is config mem.) | 2900XL, 3500XL, 2950, 3550 Switches | |
7. Restore the config-register and bring up all interfaces.
r1(config)#config-reg 0x2102 r1(config)#int s0 r1(config-if)#no shut | 1. Establish console session.
9600b, 8d, 0p, 1s, no flow control (If you had previously enabled boot-enable break, the device would respond like a router and you could follow the procedures from there.) | |
8. Record or change the passwords.
r1#sh run (or sh config) r1#config t r1(config)#enable pass donna r1(config)#enable secret harrington r1(config)#line vty 0 4 r1(config-line)#pass donna r1(config-line)#end | 2. Unplug the power cable from back of switch. Reconnect while you hold the front panel mode button. Release the mode button a couple seconds after the first port on the switch is no longer illuminated. You should see a message about the system being interrupted prior to the Flash memory file system initializing. | |
9. Save the configuration and reload.
r1#copy run start (or wr mem) r1#reload r1#sh version | 3. Type flash_init and then type load_helper. You can list the files in flash with dir flash:, and the default configuration is config.text. | |
4. Type more flash:config.text to view the passwords. If not encrypted, you are done. If encrypted, go to Step 5. | ||
5. Rename the configuration file as follows: rename flash:config.text flash:config.old. | ||
6. Boot the system with the boot command. Answer n for no to start setup. Go to enable mode by typing enable, but do not exit. | ||
7. Rename the configuration file to its original name as follows: rename flash:config.old flash:config.text. | ||
8. Copy the configuration file to memory with the config mem or copy flash:config.text system:running-config command. Accept config.text as the source and running-config as the destination filenames. | ||
9. Change the passwords.
