Verifying Connectivity, Device States, Satellite Software Versions, and Operations in a Junos Fusion

Purpose

Verify that a device is recognized as a satellite device by the aggregation device.

Action

Enter the show chassis satellite command and review the output.

Meaning

Use the output of show chassis satellite to confirm the following connections in a Junos Fusion:

• Whether a satellite device is recognized at all by the aggregation device. If the satellite device does not appear in the show chassis satellite output, then it is not recognized by the aggregation device as a satellite device.

• The state of a particular satellite device, via the Device State output.

• The state of the cascade port connection, via the Cascade State output.

Purpose

Verify that all satellite devices are recognized by the aggregation device, and that all cascade and extended ports are recognized.

Action

Enter the show chassis satellite command on the aggregation device.

Meaning

The output confirms:

• Each listed satellite device—the satellite devices are listed by alias-name in the Alias column or by FPC slot ID in the Slot column—is recognized by the aggregation device, because the Device State output is Online for every listed satellite device.

• Each cascade port is operational, because Port State is online for every cascade port. The cascade port is the port on the aggregation device that connects to the satellite device.

• The number of available and active extended ports for each satellite device, using the Extended Ports total and Extended Ports up outputs. The number of extended ports varies by satellite devices, and in this output the total number of extended ports includes both network-facing extended ports as well as uplink ports.

Purpose

Verify the hardware model of each satellite device in the Junos Fusion.

Action

Enter the show chassis satellite terse command on the aggregation device.

Meaning

The output shows the device model of each satellite device in the Device Model output, which are listed by FPC slot identification number using the Slot output.

This command is also useful for verifying the version satellite software running on each satellite device, as the version is listed in the Version output.

Purpose

Verify that the cascade port and uplink port interfaces are up.

Action

Enter the show chassis satellite interface command:

Meaning

The output shows:

• Whether the recognized port is up or down, using the State column output. The State column output is Up when the interface is up and Dn when the interface is down.

Purpose

Verify that a cascade port on an aggregation device recognizes a satellite device in the Junos Fusion. This procedure also provides a method of verifying the hardware and software information for each satellite device in the Junos Fusion.

Action

Enter the show chassis satellite neighbor command:

Meaning

The output confirms:

• The cascade ports on the aggregation device that are recognized by the Junos Fusion. All recognized cascade port interfaces are listed in the Interface output.

• The uplink ports on the satellite devices that are connected to the cascade ports. The cascade port on each satellite device is identified in the Port Info column, and the satellite device itself is identified in the System Name output.

• Whether the cascade port to uplink port connection has initialized, using the State output. The State output is Two-Way when the satellite device is properly initialized, and traffic can be passed between the aggregation device and the satellite device over the link.

• The hardware model of each satellite device in the Model column, and the satellite software running on each satellite device in the SW Version output.

Purpose

Verify that a specific extended port is recognized by the aggregation device, and is operational.

Action

Enter the show chassis satellite extended-port command on the aggregation device:

Meaning

The output confirms:

• That an extended port is recognized by the aggregation device. All extended ports are listed in the Name column of the output.

• That the listed extended ports have been added to the Junos Fusion, as shown by the AddComplete output in the State column.

• The administrative and operational state of each extended port. An extended port is operating correctly when the Admin State and Op State outputs are both in the Up state.

Purpose

Verify the satellite software versions available on the aggregation device in a Junos Fusion.

Action

Enter the show chassis satellite software command on the aggregation device.

For more detailed output, you can also enter the show chassis satellite software detail on the aggregation device.

Meaning

The version of satellite software installed is displayed in the Version or Software package version column, and the satellite software upgrade group associated with each version of satellite software is listed in the Group or Current Groups output.

Purpose

Verify the satellite software upgrade groups in the Junos Fusion, and which satellite devices are part of which satellite software upgrade groups.

A satellite software upgrade group can be a user configured group or the name of a satellite device cluster.

Action

Enter the show chassis satellite upgrade-group command on the aggregation device.

show chassis satellite upgrade-group

Meaning

The output shows that two satellite software upgrade groups—ex4300 and qfx—have been created, and that both are using satellite software version 1.0R1.1. The Group Slot output shows which satellite devices—listed by FPC slot ID number—are in which software group, and the Device State output showing version-in-sync confirms that the satellite devices are running the satellite software that is associated with the satellite software upgrade group.
