    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.

    Action

    To display the redundancy information of a line module 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:

    • - - - —Line module redundancy is not supported
    • protected—Line module redundancy is enabled
    • locked out—Line module redundancy is disabled

    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:

    • Yes—The specific criterion has been met for the system to enter the active state
    • No—The specific criterion has not been met and the system transitions to the pending state

    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"
