Monitoring Line Module and SRP Module Redundancy

You can use show commands to monitor the status of redundancy groups, line modules, and SRP modules.

Note: For more information about monitoring high availability, see Managing Modules.

show environment

• Use to display information about the hardware installed for redundancy.
• See Managing the System , for details and examples.
• See show environment.

show hardware

• Use to display detailed information about the line modules and SRP modules.
• See Monitoring Modules for details and examples.
• See show hardware.

show redundancy

• Use to display the configuration for line module redundancy and SRP redundancy.
• Field descriptions
  • SRP
    • high-availability state—State of the high availability mode (disabled, active, or pending)
    • current redundancy mode—Redundancy mode currently being used by this router (high-availability or file-system-synchronization)
    • last activation type—Last type of activation that occurred on this router (that is, the method by which the SRP last booted [cold-start or warm-start])
  • Criteria Preventing High Availability from being Active—Criteria required for HA to be active.
  • slot—Slot in which the line module resides
  • hardware role—Function of the line module: primary or spare
  • lockout config—Status of redundancy on this line module
    • protected—Line module redundancy is enabled
    • locked out—Line module redundancy is disabled
  • backed up by slot—Slot that contains the line module that is a spare for this primary line module
  • sparing for slot—Slot that contains the primary line module for which this line module is a spare
  • revert at—Time at which you want the line module to revert
  • midplane type—Identifier for the type of midplane
  • midplane rev—Hardware revision number of the redundancy midplane
  • fabric slice redundancy—Status of the fabric slice on the SRP modules or SFMs on the E120 and E320 routers
    • slot—Slot in which the fabric slice resides
    • slice state—State of the fabric slice (online, not present)
    • type—Identifier for the type of hardware (SRP module or SFM)
• Example 1

  In the following example, the user issues a show redundancy command, and then a redundancy force switchover command. Finally, the user issues the show redundancy line-card command to display information specific to the line modules. The two displays show how the states of the primary and spare line modules change.
