Appendix B Using the Offline Diagnostic Monitor Menu The administrative username and password are stored in nonvolatile random access memory (NVRAM). Each time you reboot the CSS, it reads the username and password from NVRAM and reinserts them into the user database. SuperUser status is assigned to the administrative username by default. You can change the administrative username and password, but because the information is stored in NVRAM, you cannot permanently delete them. If you delete the administrative username using the no username command, the CSS deletes the username from the running-config file, but restores the username from NVRAM when you reboot the CSS. To change the administrative username and password through the Offline DM Main menu: 1. Select option 2 from the Security Options menu. 2. Enter a username. The CSS prompts you for this username when you log in. The CSS also prompts you for this username and password if you set password protection on the Offline DM Main menu. Enter username (minimum 4 characters): 3. Enter a password. Note that the CSS does not display passwords. Enter password: 4. Reenter the password for confirmation. Confirm password: The CSS displays the Security Options menu. 5. Enter r to return to the Advanced Options menu. 6. Enter r to return to the Offline DM Main menu. 7. Enter 4 to reboot the CSS, or select another option to continue using the Offline DM Main menu. B-20 Cisco Content Services Switch Administration Guide OL-5647-02
