This chapter describes User Datagram Protocol for IPv6 (UDP6) messages. For information on message content and how to use the message, refer to the Introduction.
| UDP6.001 |
Level: U-INFO
Short Syntax: UDP6.001 pkt source_ip_address -> destination_ip_address port port_number no srvr
Long Syntax: UDP6.001 Packet from source_ip_address for destination_ip_address port port_number, no server
Description: This message is generated when a packet is discarded because either UDP6 is not installed in the router or UDP6 is installed but the packet was for the multicast address and no application supports the UDP destination port.
| UDP6.002 |
Level: U-INFO
Short Syntax: UDP6.002 pkt source_ip_address -> destination_ip_address port port_number no srvr
Long Syntax: UDP6.002 Packet from source_ip_address for destination_ip_address port port_number, no server
Description: This message is generated when a packet is discarded because either UDP6 is not installed in the router or UDP6 is installed but no UDP6 application supports the UDP6 destination port. The packet was addressed to the router.
| UDP6.003 |
Level: UE-ERROR
Short Syntax: UDP6.003 discarded pkt from source_ip_address bad len length
Long Syntax: UDP6.003 Discarded packet from source_ip_address, bad length length
Description: This message is generated when a packet is discarded because it had a UDP length greater than its IP length.
Cause: There are many possible causes of problem. The problem may originate from the sending node of this UDP6 packet, or the packet may be corrupted either during the tranmission or at this router.
Action: Trace the packet right after the sending node and right before the packet arrives at this router.
| UDP6.004 |
Level: UE-ERROR
Short Syntax: UDP6.004 bad checksum clc checksum rcv checksum
Long Syntax: UDP6.004 Bad checksum - calculated checksum, received checksum
Description: This message is generated when a packet is discarded because it had a bad checksum.
Cause: Bad checksum. Either the sending node did not perform UDP6 checksum correctly or it is possible that the UDP6 portion of this packet is corrupted.
Action: Trace the packet right after the sending node and right before the packet arrives at this router. Key on the UDP6 checksum field.
| UDP6.005 |
Level: C-TRACE
Short Syntax: UDP6.005 received pkt from ( source_IP_address, prt udp_port_number, nt Network ID)
Long Syntax: UDP6.005 received packet from ( source_IP_address, port udp_port_number, net Network ID)
Description: A UDP6 datagram has been received on a particular interface. The port number is included in the message.
| UDP6.006 |
Level: C-TRACE
Short Syntax: UDP6.006 forwarding pkt to destination_IP_address on prt udp_port_number
Long Syntax: UDP6.006 Forwarding packet to destination_IP_address on udp port udp_port_number
Description: A UDP6 datagram is being forwarded to a particular destination. The port number is included in the message.
| UDP6.007 |
Level: UE-ERROR
Short Syntax: UDP6.007 zero checksum rcv checksum
Long Syntax: UDP6.007 zero checksum - received checksum
Description: This message is generated when a packet is discarded because it had a zero checksum. (Note: UDP6 checksum is not optional like in UDP in IPV4).
Cause: Either the sending node did not perform UDP6 checksum or the checksum field in UDP6 header field is corrupted.
Action: Trace the packet right after the sending node and right before the packet arrives at this router. Key on the UDP6 checksum field.
