Why would a network administrator use the config-register 0x2102 command on a Cisco network device?

  • to monitor and manage network performance, find and solve network problems, and plan for network growth
  • to back up the running configuration onto a USB drive
  • to learn device names, IOS versions, and the number and type of interfaces of connected devices
  • to ensure that the device loads the startup configuration file during startup

Explanation: Password Recovery Procedures

Step 1. Enter the ROMMON mode.
Step 2. Change the configuration register. (enter confreg 0x2142)
Step 3. Copy the startup-config to the running-config.
Step 4. Change the password.
Step 5. Save the running-config as the new startup-config.
Step 6. Reload the device

The confreg 0x2142 command allows the user to set the configuration register to 0x2142. With the configuration register at 0x2142, the device will ignore the startup config file during startup.

After the new passwords are configured, change the configuration register back to 0x2102 by using the config-register 0x2102 command in the global configuration mode
