Active and standby switchover configuration
commands
display switchover state
Use display switchover state to display the backup state of the specified main processing unit (MPU).
Syntax
In standalone mode:
display switchover state [slot slot-number ] [ |{ begin | exclude | include } regular-expression ]
In IRF mode:
display switchover state [chassis chassis-number slot slot-number ] [ |{ begin | exclude | include }
regular-expression ]
Views
Any view
Default command level
1: Monitor level
Parameters
slot slot-number: Displays the backup state of a specified card, where slot-number represents the slot
number of a card. If no slot number is specified, the backup state of the active MPU is displayed. (In
standalone mode)
chassis chassis-number slot slot-number: Displays the backup state of a specified card on a specified
member device of an Intelligent Resilient Framework (IRF) fabric. chassis-number represents the member
ID of a member device of the IRF fabric. slot-number represents the slot number of a card. If the
slot-number argument is not provided, the backup state of the active MPU of the IRF fabric is displayed.
(In IRF mode)
|: Filters command output by specifying a regular expression. For more information about regular
expressions, see Fundamentals Configuration Guide.
begin: Displays the first line that matches the specified regular expression and all lines that follow.
exclude: Displays all lines that do not match the specified regular expression.
include: Displays all lines that match the specified regular expression.
regular-expression: Specifies a regular expression, a case-sensitive string of 1 to 256 characters.
Examples
# Display the backup state on the active MPU. (In standalone mode)
<Sysname> display switchover state
Master HA State to Slot 1: Realtime backup to slave.
# Display the backup state on the active MPU of an IRF fabric. (In IRF mode)
<Sysname> display switchover state

2
Master HA State to Chassis 1 Slot 1: Realtime backup to slave.
Master HA State to Chassis 2 Slot 5: Realtime backup to slave.
Master HA State to Chassis 2 Slot 6: Slave is absent.
Table 1 Command output
Field Descri
p
tion
Master HA State to Slot 1
Backup state between the active MPU and the standby MPU,
where 1 represents the number of the slot where the standby
MPU resides (in standalone mode).
Master HA State to Chassis 2 Slot 5
Backup state between the active MPU and an standby MPU of
the IRF fabric, where 2 represents the member ID of the device
where the standby MPU resides, and 5 represents the number of
the slot where the standby MPU resides (in IRF mode).
Slave is absent The standby MPU is not in the slot.
Waiting batch backup request from slave Waiting for the batch backup requests from the standby MPU.
Batch backup Batch backup state.
Realtime backup to slave Real-time backup state.
Data smooth Data smoothing state.
# Display the backup state on the standby MPU in slot 1. (In standalone mode)

ha slave-ignore-version-check
Use ha slave-ignore-version-check to ignore version check of the standby MPU, which means not to
check whether the version of the standby MPU is consistent with that of the active MPU.
Use undo ha slave-ignore-version-check to enable version check of the standby MPU.
Syntax

2: System level
Usage guidelines
Inconsistency of the software version of the active MPU and standby MPU can result in system failure
when the system is running.
If the software versions of the active MPU and standby MPU are greatly different, or the software
difference affects the use of the device, even if the ha slave-ignore-version-check command is configured,
the standby MPU is not necessarily started. To ensure the normal operation of the device, use the same
software version for the active MPU and standby MPU.
When the device is operating in IRF mode, this command is not supported. To switch between the
standalone mode and IRF mode, use the chassis convert mode irf command.
Examples
# Ignore version check of the standby MPU.
