Monitoring the Redundancy Status of Line Modules in a Specific Slot
Purpose
Display the supported redundancy modes as well as other status relating to high availability for a line module installed in a particular slot.

Table 1: show redundancy line-card slot slotNum Output Fields
Field Name | Field Description |
|---|---|
Line Card | Redundancy and configuration details for the line module in the specified slot |
High Availability State | State of the high availability mode of the line module in the specified slot (disabled or active) |
last activation type | Last type of activation that occurred on this router (that is, the method by which the line module last booted [cold-start or warm-start]) |
automatic reverting | Whether the router is enabled to revert from all spare line modules to the associated primary line modules automatically: on or off |
slot | Slot number in which the line module resides |
hardware role | Function of the line module: primary or spare. |
lockout config | Status of redundancy on the line module:
|
sparing for slot | Slot that contains the line module that is a spare for this primary line module |
backed up by slot | Slot that contains the primary line module for which this module is a spare |
revert at | Time at which you want the line module to revert |
Criteria Preventing High Availability from being Active | Criteria preventing the router from being in the active state of high availability mode. For the router to be in the Active state, all criteria for this option must be "yes" |
criterion | Name of the criterion that must be met for the system to enter the active state of the stateful line module switchover process. During the active state, the mirroring subsystem synchronizes the secondary line module with the primary line module by mirroring updates to mirrored volatile storage |
slot | Slot number in which the line module resides |
met | Whether the criterion for high availability of the line-module pair is satisfied. Possible values:
|
Clients with Unsafe Configurations for High Availability | Whether the client supports high availability and also the safety level of configuration |
client | Name of the application that is running on the line module configured for high availability |
mode | High availability status of the application running on the line module: supported or unsupported |
configuration | Safety level of the configuration based on whether or not the client is supported or unsupported and in case of those unsupported, whether or not the client has been configured. For example, if an unsupported client has been configured on a router with high availability enabled, the configuration reads "unsafe" |
