Monitoring Chassis Information

The chassis properties include the status of hardware components on the device. To view these chassis properties, select Monitor>System View>Chassis Information in the J-Web interface.

Alternatively, you can view chassis details by entering the following show commands in the CLI configuration editor:

• show chassis hardware
• show chassis routing-engine
• show chassis environment
• show chassis redundant-power-supply
• show redundant-power-supply status

Caution: Do not install a combination of PIMs in a single chassis that exceeds the maximum power and heat capacity of the chassis. If J Series power management is enabled, PIMs that exceed the maximum power and heat limits remain offline when the chassis is powered on. To check PIM power and heat status, use the show chassis fpc and show chassis power-ratings commands. For more information, see the J Series Services Routers Hardware Guide.

The Chassis Information page displays the following types of information:

• Routing Engine Details—This section of the page includes the following tabs:
  • Master—The Master tab displays information about the routing engine, including the routing engine module, model number, version, part number, serial number, memory utilization, temperature, and start time. Additionally, this tab displays the CPU load averages for the last 1, 5, and 15 minutes.

    Note: On some devices, you can have an FPC state as “offline.” You may want to put an FPC offline because of an error or if the FPC is not responding. You can put the FPC offline by using the CLI command request chassis fpc slot number offline.

  • Sub-Component—The Sub-Component tab displays information about the device’s sub-components (if applicable). Details include the sub-component’s version, part number, serial number, and description.

To control which component details are displayed, select a hardware component from the Select component list.

IOC to NPC Mapping

An Input/Output card (IOC) to Network Processing Card (NPC) mapping requires you to map one IOC to one NPC. However, you can map multiple IOCs to a single NPC. To balance the processing power in the NPC on the SRX3400 and SRX3600 Services Gateways, the chassis process (daemon) runs an algorithm that performs the mapping. It maps an IOC to an NPC that has the least amount of IOCs mapped to it. You can also use the command-line interface (CLI) to assign a specific IOC to a specific NPC. When you configure the mapping, the chassis process will first use your configuration, then apply the least-number NPC algorithm for the rest of the IOCs.

You can configure the IOC to NPC mapping using the following example:

The set chassis ioc-npc-connectivity options are described in Table 51:

Note: You must restart the chassis control after you commit the set chassis ioc-npc-connectivity CLI command.

Monitoring Process Details

The process details indicates the status of each of the individual processes running on the device. To view these details, select Monitor>System View>Process Details in the J-Web interface.

Alternatively, you can view chassis details by entering the following show commands in the CLI configuration editor:
