debugging vrrp

Function

The debugging vrrp command enables all debugging functions of VRRP and outputs debugging information.

The undo debugging vrrp command disables all debugging functions of VRRP.

By default, VRRP debugging functions are disabled.

Format

debugging vrrp event

debugging vrrp packet [ interface { interfaceName | ifType ifNum } [ vrid vrid-Value ] ]

debugging vrrp state [ interface { interfaceName | ifType ifNum } [ vrid vrid-Value ] ]

debugging vrrp timer [ interface { interfaceName | ifType ifNum } [ vrid vrid-Value ] ]

debugging vrrp trace [ interface { interfaceName | ifType ifNum } [ vrid vrid-Value ] ]

undo debugging vrrp event

undo debugging vrrp packet [ interface { interfaceName | ifType ifNum } [ vrid vrid-Value ] ]

undo debugging vrrp state [ interface { interfaceName | ifType ifNum } [ vrid vrid-Value ] ]

undo debugging vrrp timer [ interface { interfaceName | ifType ifNum } [ vrid vrid-Value ] ]

undo debugging vrrp all

undo debugging vrrp trace [ interface { interfaceName | ifType ifNum } [ vrid vrid-Value ] ]

Parameters

Parameter	Description	Value
packet	Enables the VRRP packet debugging function.	-
interface ifType ifNum	Specifies the type and number of an interface on which a VRRP group is configured.	-
interface interfaceName	Specifies an interface on which a VRRP group is configured.	-
vrid vrid-Value	Specifies the ID of a VRRP group.	The value is an integer ranging from 1 to 255.
state	Enables the VRRP status debugging function.	-
timer	Enables the VRRP timer debugging function.	-
trace	Enables the VRRP trace debugging function.	-
event	Enables debugging of information about interaction between the VRRP module and external modules.	-
all	Disables all VRRP debugging functions.	-

Usage Guidelines

Usage Scenario

When the master device and backup device become abnormal during switchover, the debugging vrrp packet command enables debugging of VRRP packets and displays detailed information about sent and received VRRP packets. This command can be run to locate the fault.
When status changeover of the VRRP group becomes abnormal, the debugging vrrp state command enables status debugging of VRRP and displays the status changeover information about the VRRP group. This command can be run to locate the fault.
When status changeover of the VRRP group becomes abnormal, the debugging vrrp timer command enables timer debugging of VRRP and displays the timer timeout information about the VRRP group. This command can be run to locate the fault.
When status changeover of the VRRP group becomes abnormal, the debugging vrrptrace command enables timer debugging of VRRP and displays the trace information about the VRRP group. This command can be run to locate the fault.
When the interaction between the VRRP module and the external module becomes abnormal, the debugging vrrp event command enables debugging of VRRP event and displays detailed information. This command can be run to locate the fault.

Example

# Enable the debugging function for the exchange between VRRP and external modules.
