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

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.
