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.

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"
