Monitoring Stateful SRP Switchover
This section shows how to use the show commands to view your high availability configuration
and how to clear the high availability switchover history for the
router.
Stateful SRP Switchover show Commands
You can monitor various aspects of stateful SRP
switchover using show commands. These aspects
include redundancy modes and status, redundancy clients, historical
information about redundancy on the router, and specific redundancy
information for line modules and SRPs.
show ip interface
show ipv6 interface
- Use to display the initial sequence preference values
as well as other information relating to the current state of all
IP or IPv6 interfaces or the IP or IPv6 interfaces you specify.
- Field descriptions relating to redundancy. These fields
are displayed when the brief keyword is
not issued.
- Operational initial sequence preference—Actual initial
sequence preference as determined by the combination of the protocol
configured on the interface and the CLI configuration on the interface;
the value is 0 (low priority) or 1 (high priority)
- Administrative—Configured initial sequence preference
specified with the ip initial-sequence-preference command or the ipv6 initial-sequence-preference command; the value is 0 (low priority) or 1 (high priority)
- Example 1—Displays a summary of the redundancy status
of an ERX14xx model
host1#show ip interface atm 2/0.1
ATM2/0.10 line protocol Atm1483 is up, ip is up
...
Warm-restart initial-sequence-preference: Operational = 1 Administrative = 1
...
show redundancy
- Use to display the supported redundancy modes and other
status relating to stateful SRP switchover. In particular, the output
indicates any conditions that are preventing high availability from
operating.
- Field descriptions
- SRP
- high-availability state—State of the high availability
mode (disabled, active, or pending)
- current redundancy mode—Redundancy mode currently
being used by this router (high-availability or file-system-synchronization)
- last activation type—Last type of activation that
occurred on this router (that is, the method by which the SRP last
booted [cold-switch or warm-switch])
- Criteria Preventing High Availability from being Active—criteria
required for high availability to be active.
- Criteria Required for High Availability to be Active—criteria
required for high availability to be active.
 |
Note:
All criteria for both options must be “yes” for
high availability to be active.
|
- Line Card
- automatic reverting—State of automatic reverting
(on or off)
- slots—Slots in which the line modules reside
- hardware role—Function of the line module: primary
or spare
- lockout config—Status of redundancy on this 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 line module is a spare
- revert at—Time at which you want 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 (online, not
present)
- type—Identifier for the type of hardware (SRP module
or SFM)

- See show redundancy.
show redundancy clients
- Use to display high availability clients and their various
levels of high availability support.
- Specify an optional client type that you want to view
(all, supported, unsafe, unsupported)
|
Note:
Issuing this command without the optional client type results
in showing only unsupported high availability clients (the default).
|
- Field descriptions
- client—High availability client
- mode—Whether the client is supported or unsupported
for high availability
- configuration—Safety level of the configuration
based on whether or not the client is supported or unsupported and,
in the case of those unsupported, whether or not the client has been
configured. For example, if an unsupported client is configured on
a router with high availability enabled, the configuration reads “unsafe”.
