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 Module Redundancy. |
show environment
- Use to display information about the hardware installed for redundancy.
- See Managing the System in the JUNOSe System Basics Configuration Guide for details and examples.
- See show environment.
show hardware
- Use to display detailed information about the line modules and SRP modules.
- See Monitoring Modules in the JUNOSe System Basics Configuration Guide 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 high availability 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
- state—State of the fabric slice (online, not present)
- type—Identifier for the type of hardware (SRP module or SFM)
- SRP
- 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.
