Field Name

Field Description

SRP

high-availability state

State of high availability mode:

  • disabled—Initial, default state for high-availability mode. The router continues to use file system synchronization.
  • active—Data synchronized from the active SRP module to the standby SRP module during initialization remains synchronized through mirroring updates.
  • pending—If an unsupported application is configured, the router transitions to this state.
  • initializing—If SRP module is in initializing state, bulk synchronization of memory and NVS occurs.

current redundancy mode

Redundancy mode currently used by the router:

  • high-availability—Ensures rapid SRP module recovery after a switchover by using initial bulk file transfer and subsequent, transaction-based mirroring.
  • file-system-synchronization—Default redundancy mode of the router. SRP modules reload all line modules and restart form saved configuration files.

last activation type

Last type of activation that occurred on the router. The method using which the SRP last booted:

  • cold-start—When the router is in pending state and switchover occurs, the router undergoes a cold-start or cold switch.
  • warm-start—When the router is in active state and switchover occurs, the router undergoes a warm switch or
    warm-start.

Criteria Preventing High Availability from being Active

Criteria preventing the router from being in the active state of high availability mode.

Note: For the router to be in the Active state, all criteria for this option must be “yes”.

Criteria Required for High Availability to be Active

Criteria required for the router to be in the active state of high availability mode.

Note: For the router to be in the Active state, all criteria for this option must be “yes”.

Line Card

automatic reverting

State of automatic reverting. Possible states: on or off.

slots

Slots in which the line modules reside.

hardware role

Function of the line module. Possible values: primary or spare.

lockout config

Status of redundancy on the 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 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. Possible values: online or not present.

type

Identifier for the type of hardware. Possible values: SRP modules or SFM modules.
