Password Recovery

If the administrator forgets the login password and cannot enter the configuration mode for configuration, then you need to use the configuration line to enter the CTRL layer for password recovery.
*Notes on password recovery

• When doing password recovery, please prepare the console line first.
• Password recovery is an operation that is completed when you enter the CTRL layer when you restart the device. You need to disconnect the network to proceed. Please perform password recovery when it is convenient to disconnect the network.
• Please strictly follow the operation steps, improper operation will cause configuration loss.
• The password recovery of the switch is the password recovery of saving the configuration mode.
• After entering the CLI command line interface, if you do not enter any keys within 10 minutes, you still need to enter the password after the timeout. Or the password has not been changed after input, the device will use the previous password after the next restart.
