Troubleshooting with the CLI on the SRX1400 Services Gateway


The Junos OS command-line interface (CLI) is the primary tool for controlling and troubleshooting services gateway hardware, Junos OS, routing protocols, and network connectivity. CLI commands display information from routing tables, information specific to routing protocols, and information about network connectivity derived from the ping and traceroute utilities. CLI commands are entered on one or more external management devices. These devices are connected to the services gateway through the CONSOLE port on the SYSIOC.

You can use the CLI to display details about alarms generated by interfaces and hardware components as shown in examples below:

  • Use the CLI show chassis fpc command to check the status of the installed cards. As shown in the sample output, the value Online in the column labeled State indicates that the card is functioning normally:

    user@host> show chassis fpc
  • Using a question mark (?) gives you a listing of the various options for the command as shown below:

    user@host> show chassis fpc ?
  • To view information about a particular card in the chassis, use the fpc slot option:

    user@host> show chassis fpc 3
  • For more detailed output, add the detail option. The following example does not specify a slot number, which is optional:

    user@host> show chassis fpc detail

For further descriptions of the output from the commands, see the Junos System Basics and Services Command Reference.


The set chassis ioc-npc-connectivity command is not supported on the SRX1400 Services Gateway.

You can also view the chassis properties in the J-Web interface by selecting Monitor>Chassis. For more information on troubleshooting the individual hardware components, see the following topics:
