1. When the enabling password of Ruijie switch exists but is forgotten, it is necessary to connect the console port of the switch with a configuration line to clear the switch settings, establish a connection with the switch with HyperTerminal, start the switch, and clear the enabling within three seconds after the switch is powered on.

2. Use the console to connect the device to restart, press Ctrl+C according to the prompt to enter the Ctrl layer, and then delete the configuration file. If you need to keep the configuration file, you can rename the configuration file first, then restart it, change the configuration file name back after entering the enabling mode, and command the switch to load the configuration file.

3. Enter the crt, click the quick link button to select the protocol you use when connecting, com for serial connection, ssh2 or telnet for remote connection, and then, the user and password. If your connection is normal, then you can link it. The Ssh2 protocol requires a user name and password, but telnet does not.

4. Problem description: Our router switch is a Cisco device, and we forgot the password of the switch before. What if I lose my password? Please ask the master for advice.

5. Call the customer service department for technical documents. Each model of Ruijie has a different password reset method. Last time I called 400 questions.

6. At startup, press Ctrl+B to enter the BOOTROM directory. Enter the password of BOOTROM. Enter 7 to clear the console password. Enter 1 to enter the system default mode (important note: 1 must be selected instead of 8, and a password is required if 8 is selected).
