Troubleshooting USG2000&5000 series device restart
Roadmap for troubleshooting device restart: First check whether the screen does not respond to input after you run the commands, such as save. This is a zombie status. You have to wait for a while about one minute. Then check whether the hardware environment changes when the fault occurs, for example, the device falls off, the lightening strikes, the power supply voltage is unstable, or the interface card is installed and removed during power-on. Such operations result in device hardware damages. If the device restarts repeatedly, you should first check whether the BootROM or system software is upgraded. The unmatched upgrade version leads to repeated restart. If all the preceding faults are rectified, the system bug may be the cause of the restart. Troubleshooting procedure: 1. Ensure that you do not perform such operations as entering or saving the configuration, and downloading files. This is a zombie status. You have to wait for a while and the problem is automatically resolved. 2. You cannot rectify the faults, such as hardware damages or software bugs. Please contact the technical support personnel.

Defining services for the USG2000&5000 series
The USG2000&5000 series supports defining services using the web UI or CLI. Service can be used as a security policy matching condition.

Enter or select service information, including the name, description, and protocol, and click Apply. Defining services using the CLI: 1. Run the ip service-set service-set-name type object [ vpn-instance vpn-instance-name ] command in the system view to create a service set and access its view. 2. Add members to this service set. a. Run the service [ id ] protocol { udp | tcp | sctp } [ source-port { src-port-number-1 [ to src-port-number-2 ] } &<1-64> | destination-port { dst-port-number-1 [ to dst-port-number-2 ] } &<1-64> ] * [ description description ] command to specify protocol types, such as TCP, UDP, or SCTP, by port number ranges. b. Run the service [ id ] protocol icmp [ icmp-type { icmp-name | icmp-type-number icmp-code-number } ] [ description description ] command to specify the ICMP message type or code. c. Run the service [ id ] protocol protocol-number [ description description ] command to specify the protocol field value in IP packet headers to specify the protocol type. 3.
