Item

Description

General Packet Errors

General packet errors.

Bad packet

The parsed packet is incorrect, including the checksum of the length field.

Bad version

The OSPFv3 version is incorrect (not version 3).

Bad area ID

The area IDs in the received packets are different from the local area ID, except area 0, and other area IDs are considered incorrect.

Bad virtual link

Virtual link receives invalid packets.

Packet too small

Length of the received packet is not equal to the sum of length of IP header and the length of the packet.

Transmit error

Transmitting packets to socket fails.

Interface down

Number of times that the OSPFv3 interface goes Down.

Unknown neighbor

OSPFv3 packets are received from non-OSPFv3 neighbors on NBMA networks, virtual links, and sham links.

Authentication failure

Number of packets that fail to be authenticated.

AuthSeqNum mismatch

Number of bad authentication sequence number errors.

AuthKeyId mismatch

Number of packets with key IDs different from the local one.

IPv6: received my own packet

Number of IPv6 packets that were generated locally but received again from neighbors.

Bad Checksum

Number of packets for which checksum calculation failed.

Hello Packet Errors

Title bar: Hello packet errors.

Hello timer mismatch

The Hello interval is not consistent.

Dead timer mismatch

The Dead interval is not consistent.

Extern option mismatch

The extension attributes of the Hello packet are not consistent.

Router ID confusion

A router ID conflict occurs.

Virtual neighbor unknown

The router ID of the packet is inconsistent with that of the V-link neighbor.

Invalid DR

Statistics about Hello packets with non-zero DR priorities received by a P2P interface.

DD packet errors

Title bar: DD packet errors.

Neighbor state low

Cases of errors:
  • A DD packet is received, but its neighbor status is lower than 2-way.

  • An LSR packet is received, but its neighbor status is lower than Exchange.

  • An LSU packet is received, but its neighbor status is lower than Exchange.

  • An ACK packet is received, but its neighbor status is lower than Exchange.

Extern option mismatch

The Option of the DD packets is not matched.

Unknown LSA Type

The router receives unknown LSAs.

MTU option mismatch

The MTU value of the DD packet that is received on the interface is greater than that of this interface.

LS Ack Packet Errors

Title bar: LS ACK packet errors.

LS REQ packet Errors

Title bar: LS REQ packet errors.

Bad request

BadRequest event in the protocol.

Empty Request

Indicates empty LSR packets.

LS UPD Pcket Errors

Title bar: LS UPD packet error.

LSA checksum bad

Indicates that the LSA checksum is incorrect.

Received less recent LSA

An LSA that is older than the local copy is received.

Newer self-generate LSA

Indicates the number of new self-generated LSAs. This field is reserved for future use.

Received LSA within LSA Arrival interval

An LSA is received within the LSA arrival interval.

Receive Grace LSA Errors

Indicates the number of received incorrect Grace LSAs.

Number of invalid LSAs

Total number of invalid LSAs.

Number of policy failed LSAs

Total number of policy failed LSAs.

Number of wrong period LSAs

Total number of wrong period LSAs.
