NOTE: While in the active and pending states, the CLI synchronize command does
not update configuration files; these files are updated by the mirroring process.
During the active state:
NOTE: Changes made in manual commit mode are maintained, uncommitted, in
the standby SRP memory until a trigger to commit occurs; if a switchover occurs
while in this mode, the standby SRP module uses the configuration in memory.

Pending State

The system transitions to the pending state if an unsupported application is
configured. When a transition to the pending state occurs, the system generates
SNMP traps and log messages.
How the router behaves depends on which HA state the application is in when it
shifts to a pending state:
The system remains in the pending state until the configuration of the unsupported
application is removed. However, even though it is in the pending state, the system
continues mirroring updates from the primary SRP module to the standby SRP
module.
The standby SRP module replays the updates (in the order in which they were
committed on the active SRP module) and makes the appropriate changes for
each changed application.
Updates that need to be stored in NVS (that is, for static configurations) are
updated in NVS.
If a switchover occurs while the router is in the active state, the standby SRP
module performs a warm restart (that is, stateful SRP switchover is in effect);
the standby SRP module uses the configuration located in NVS.
If an unsupported application is configured, the system transitions to the pending
state.
If any other criterion changes (is no longer met), the system transitions to the
disabled state.
From disabled state The router remains in the disabled state.
From initializing state The router completes the initializing state and transitions
to the pending state after initialization is complete.
Active State The router transitions to the pending state.
