debugging ospfv3 packet

Function

The debugging ospfv3 packet command enables debugging of all types of sent and received OSPFv3 packets.

The undo debugging ospfv3 packet command disables debugging of all types of sent and received OSPFv3 packets.

By default, the debugging of all types of sent and received OSPFv3 packets is disabled.

Format

debugging ospfv3 process-id packet { { ack | all | dd | hello | request | update } [ received | sent ] [ { interfacename | interfacetype interfacenum } [ neighbor-id ] | area { area-id | area-id } ] [ verbose ] }

debugging ospfv3 packet { { ack | all | dd | hello | request | update } [ received | sent ] [ verbose ] }

undo debugging ospfv3 process-id packet { { ack | all | dd | hello | request | update } [ received | sent ] [ { interfacename | interfacetype interfacenum } [ neighbor-id ] | area { area-id | area-id } ] [ verbose ] }

undo debugging ospfv3 packet { { ack | all | dd | hello | request | update } [ received | sent ] [ verbose ] }

Parameters

Parameter	Description	Value
process-id	Specifies the ID of an OSPFv3 process.	The value is an integer ranging from 1 to 4294967295.
ack	Displays debugging information about type-5 OSPFv3 packets.	-
all	Displays debugging information about all types of OSPFv3 packets.	-
dd	Displays debugging information about type-2 OSPFv3 packets.	-
hello	Displays debugging information about type-1 OSPFv3 packets.	-
request	Displays debugging information about type-3 OSPFv3 packets.	-
update	Displays debugging information about type-4 OSPFv3 packets.	-
received	Displays debugging information about received connection packets. All received connection packets are output.	-
sent	Displays debugging information about sent connection packets. All sent connection packets are output.	-
interfacename	Interface name.	-
interfacetype	Interface type.	-
interfacenum	Interface number.	-
neighbor-id	Specifies the neighbor Router ID.	The value is in dotted decimal notation.
area area-id	Specifies the area ID for the area to be debugged.	The value can be a decimal integer ranging from 0 to 4294967295 or in the format of an IP address.
verbose	Displays detailed debugging information of sent and received OSPFv3 packets.	-

Usage Guidelines

Usage Scenario

The debugging ospfv3 packet command enables debugging of all types of sent and received OSPFv3 packets. Generally, this command can be used to check the creation of neighbors and trace problems in the process. If a problem occurs, enable debugging of the related type of packet.

If the OSPFv3 process ID is not specified, the packets of all OSPFv3 processes are displayed.

OSPFv3 packets are ack, dd, hello, request, and update packets. This command displays the information about all types of packets.

Debugging affects the system performance. After debugging is complete, run the undo debugging ospfv3 packet command in time to disable debugging of OSPFv3 packets.

Example

# Enable debugging of OSPFv3 hello packets.
