Availability to be Active

Field Description
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.
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 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.
NOTE: All criteria must be "yes" for high availability
to be active.
