Configuring Active And Standby Switchover; Active And Standby Switchover Configuration Task List; Ignoring Version Check Of The Standby Mpu - HPE FlexNetwork HSR6800 series Configuration Manual

Configuring active and standby
switchover
If a device has two MPUs, the MPU that forwards and processes packets is called the active MPU,
and the MPU that is in the standby state is called the standby MPU. The system uses the MPU with
a smaller slot number as the active MPU, and the other MPU as the standby MPU. The standby MPU
keeps its configuration the same as the active MPU through the synchronization function. When the
active MPU fails, the standby MPU becomes the active MPU to process services to ensure the
normal operation of the device. This switchover process is called an active and standby switchover.
Active and standby switchover functions in the following ways:
•
Automatic active and standby switchover. If the active MPU fails or is removed, the system
automatically performs an active and standby switchover to enable the standby MPU to function
as the active MPU.
•
Manual active and standby switchover, which is an active and standby switchover performed at
the command line interface.

•
The tasks in this chapter can be performed only when the device is operating in standalone
mode. In IRF mode, only the display switchover state command takes effect. For more
information about IRF, see IRF Configuration Guide.
•
Active/standby switchover configuration tasks must be performed at the CLI of the active MPU.
The system can automatically propagate the configuration to the standby MPU.

Ignoring version check of the standby MPU
When the standby MPU attempts to start up, the system by default examines its software version
against the software version on the active MPU for inconsistency. If the versions of the active MPU
and standby MPU are not consistent, the standby MPU cannot be started.
To disable the system from examining the software version of the standby MPU:
Step
1. Enter system view.
2. Ignore version check of the
standby MPU.
