debugging ospf packet

Function

The debugging ospf packet command enables debugging of all types of sent and received OSPF packets.

The undo debugging ospf packet command disables debugging of sent and received OSPF packets.

By default, the debugging of sent and received OSPF packets is disabled.

Format

debugging ospf process-id packet [ ack | dd | hello | request | update ] [ interface { interfacename | interfacetype interfacenum } ] [ brief ] [ filter { { src | nbr } { nbrId | acl { acl-number | acl-name } } } ]

debugging ospf process-id packet grace

debugging ospf process-id packet filter { { src | nbr } nbrId }

undo debugging ospf [ process-id ] packet [ ack | dd | hello | request | update ] [ interface { interfacename | interfacetype interfacenum } ] [ brief ] [ filter { { src | nbr } { nbrId | acl { acl-number | acl-name } } } ]

undo debugging ospf [ process-id ] packet grace

undo debugging ospf process-id packet filter { { src | nbr } nbrId }

Parameters

Parameter	Description	Value
process-id	Specifies the ID of an OSPF process.	The value is an integer ranging from 1 to 4294967295.
ack	Displays debugging information about type-5 OSPF packets.	-
dd	Displays debugging information about type-2 OSPF packets.	-
hello	Displays debugging information about type-1 OSPF packets.	-
request	Displays debugging information about type-3 OSPF packets.	-
update	Displays debugging information about type-4 OSPF packets.	-
interface interfacetype interfacenum	Specifies the type and number of an interface.	-
brief	Displays the brief OSPF information.	-
filter	Set filter policy.	-
src	Set filter policy of Self device.	-
nbr	Set filter policy of Neighbor device.	-
nbrId	Specifies the IP address.	The value is in dotted decimal notation.
acl acl-number	Specifies the number of a basic ACL.	The value is an integer ranging from 2000 to 2999.
acl acl-name	Specifies the name of a named basic ACL.	The value is a string of 1 to 64 case-sensitive characters without spaces. The value must start with a letter (a to z or A to Z, case sensitive).
grace	Displays debugging information about Grace LSA in update packet.	-

Usage Guidelines

Usage Scenario

The debugging ospf packet command enables debugging of all types of sent and received OSPF packets. Generally, this command can be used to check the creation of neighbors and locate problems in the process. If a problem occurs, enable debugging of the related type of packet. If the OSPF process ID is not specified, the packets of all OSPF processes are displayed. OSPF 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 ospf packet command in time to disable debugging of OSPF packets.

Example

# Enable the OPSF Hello packet debugging after OSPF SR is enabled.
