Output Fields
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-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 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.
