Juniper firewall configuration backup

To prevent network interruptions caused by the failure of the Juniper firewall device and ensure uninterrupted operation of user services, we will describe the rapid recovery of the Juniper firewall under the fault.
One of the backup configurations of the Juniper firewall and the restart of the device: if the system reset is required when the Juniper firewall is abnormal during work, restart the firewall using the reset command on the console cable, during the restart, you can view the firewall startup information on the operating terminal.
Juniper firewall configuration backup II. Operating System Backup: during routine maintenance, you can back up the firewall operating system screnos to a local device by starting the tftp server and executing the following command line: save software from flash to tftp x. x. x. x filename.
Juniper firewall configuration backup 3, operating system recovery: When the firewall is abnormal, you can quickly restore the firewall operating system in two ways, command line method: save software from tftp x. x. x. x filename to flash, or select the Firmware Update (screnos) option under Configuration> Update> screnos/Keys on the web, and select the local screnos File in the Load File column, then, click the apply button. After the screnos file is uploaded, the firewall restarts automatically.

During routine maintenance, you can back up the firewall configuration information to the local device for fault recovery. There are three ways to operate:
1. Start the tftp server and run: save config from flash to tftp x. x filename under the command line.
2. Remotely telnet/ssh to the firewall through the Super Terminal, and record the get config configuration information to the local device through log record.
3. Back up the Configuration File on the web page: Configuration> Update> Config file, and click save to File.
Juniper firewall configuration backup 5. configuration file recovery:
If the current configuration information of the firewall is incorrect, you need to quickly restore the configuration information. There are three ways to perform this operation:
1. Start the tftp server and run: save config from tftp x. x filename to flash under the command line. After the configuration file is uploaded, run the reset command to restart the server.
2. Restore the Configuration File through the web page: Configuration> Update> Config File, select Replace Current Configuration, and select the backup Configuration File for recovery from the local device, after you click apply, the system restarts to make the new configuration take effect.
3. Remotely telnet/ssh to the firewall through the Super Terminal, clear the firewall configuration through the unset all command, restart the firewall, and paste the backup configuration command into the firewall.
Juniper firewall configuration backup 6. Restore factory value: the console cable is connected to the firewall, the firewall is restarted through the reset command, and the firewall's 16-bit serial number is used as the account/password for login, you can quickly restore the firewall configuration to the factory value.
Juniper firewall configuration backup 7. Hardware troubleshooting:
When a fault occurs in the firewall and the configuration fault and screnos software fault have been ruled out, you can switch to the slave device through NSP to resume network operation and further locate the hardware fault. Switch Mode: 1. Unplug the upstream and downstream Network cables of the active firewall (the HA connection of the active firewall must be unplugged only when the power is off ), the firewall automatically performs master-slave switchover. 2. You can also run the following command on the master device: exec NSP sealing group id 0 mode backup, and manually run the firewall active/standby switchover.
Juniper firewall configuration backup (RMA): If Juniper confirms that the firewall has a hardware fault, please contact the equipment agent in time. The device agent will perform RMA (device repair) on damaged parts or equipment during the warranty period according to the repair process ).
