    Monitoring the Redundancy Status of SRP Modules

    Purpose

    Display redundancy information specific to SRP modules.

    Action

    To display the redundancy status of the SRP modules. 

    host1#show redundancy srp
    
    high-availability state:  active
    current redundancy mode:  high-availability
    last activation type:     warm-switch

    To display the redundancy status of the SRP modules in detail.

    host1#show redundancy srp detail
    
    high-availability state:  disabled
    current redundancy mode:  file-system-synchronization
    last activation type:     cold-start
       Criteria Required for High Availability to be Active
       ----------------------------------------------------
                         criterion                         met
    ----------------------------------------------------   ---
    Active SRP hardware supports High Availability?        Yes
    High Availability mode configured?                     No
    Mirroring Subsystem present?                           Yes
    Mirroring activity levels within limits?               Yes
    Network Core Dumps disabled?                           Yes
    Running configuration is safe for High Availability?   Yes
    Standby SRP hardware supports High Availability?       Yes
    Standby SRP is online and capable of mirroring?        Yes
    Standby SRP is running the same release?               Yes

    Meaning

    Table 1: show redundancy srp Output Fields

    Field Name

    Field Description

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

    Criteria Required for High Availability to be Active

    Criteria required for high availability to be active.

    Note: All criteria must be “yes” for high availability to be active.
