Output Fields

Table 1 lists the output fields for the show chassis cluster interfaces command. Output fields are listed in the approximate order in which they appear.

Table 1: show chassis cluster interfaces Output Fields

Field Name

Field Description

Control link status

State of the chassis cluster control interface: up or down.

Control interfaces

  • Index—Index number of the chassis cluster control interface.

  • Interface—Name of the chassis cluster control interface. The control interface names differ based on the routing engine. For RE2, the control interfaces are displayed as em0 and em1 and for RE3, the control interfaces are displayed as ixlv0 and igb0.

  • Monitored-Status—Monitored state of the interface: up or down.

  • Internal SA—State of the internal SA option on the chassis cluster control link: enabled or disabled.

    Note:

    This field is available only on SRX5000 line devices.

  • Security—State of MACsec on chassis cluster control interfaces.

Fabric link status

State of the fabric interface: up or down.

Fabric interfaces

  • Name—Name of the fabric interface.

  • Child-interface—Name of the child fabric interface.

  • Status—State of the interface: up or down.

  • Security—State of MACsec on chassis cluster fabric interfaces.

Redundant-ethernet Information

  • Name—Name of the redundant Ethernet interface.

  • Status—State of the interface: up or down.

  • Redundancy-group—Identification number (1–255) of the redundancy group associated with the redundant Ethernet interface.

Redundant-pseudo-interface Information

  • Name—Name of the redundant pseudointerface.

  • Status—State of the redundant pseudointerface: up or down.

  • Redundancy-group—Identification number (1–255) of the redundancy group associated with the redundant pseudointerface.

Interface Monitoring

  • Interface—Name of the interface to be monitored.

  • Weight—Relative importance of the interface to redundancy group operation.

  • Status—State of the interface: up or down.

  • Redundancy-group—Identification number of the redundancy group associated with the interface.

The following output is specific to SRX5400, SRX5600, and SRX5800 devices in a chassis cluster cluster, when the PICs containing fabric links on the SRX5K-MPC3-40G10G (IOC3) are powered off to turn on alternate PICs. If no alternate fabric links are configured on the PICs that are turned on, RTO synchronous communication between the two nodes stops and the chassis cluster session state will not back up, because the fabric link is missing.
