This chapter describes Network Dispatcher Router (NDR) messages. For information on message content and how to use the message, refer to the Introduction.
| NDR.001 |
Level: P-TRACE
Short Syntax: NDR.001 rcv source_ip_address -> destination_ip_address
Long Syntax: NDR.001 Receiving packet from source_ip_address for destination_ip_address
Description: This message is generated for each packet which has passed first-level reasonableness checks.
| NDR.002 |
Level: C-TRACE
Short Syntax: NDR.002 frg pkt source_ip_address -> destination_ip_address
Long Syntax: NDR.002 Packet from source_ip_address for destination_ip_address requires fragmentation
Description: This message is generated when an IP packet needs to be fragmented for transmission.
| NDR.003 |
Level: UE-ERROR
Short Syntax: NDR.003 LL broadcast source_ip_address -> destination_ip_address, discarded
Long Syntax: NDR.003 Received link level broadcast from source_ip_address for destination_ip_address, discarded
Description: This message is generated when an attempt is made to forward an IP packet that was received as a link level broadcast/multicast. Such packets are not forwarded, and are discarded without even sending back an ICMP message to the source.
| NDR.004 |
Level: CE-ERROR
Short Syntax: NDR.004 TTL zero source_ip_address -> destination_ip_address
Long Syntax: NDR.004 Time-to-live expired on packet from source_ip_address for destination_ip_address
Description: This message is generated when a packet is discarded because the time-to-live expired.
Cause: The packet has been through more routers than the initial value placed in the time-to-live field of the IP header by the originator. Many older systems use values of 15 or 30, which are not standard-conformant, and are often too small for current networks.
Action: Increase initial time-to-live value.
Cause: The packet was in a routing loop, going through a sequence of routers over and over until the time-to-live expired.
Action: Check the routing from the source of the packet to the destination, and see that there are no loops. However, temporary loops are an inevitable result of the timing out of routes in some routing protocols.
| NDR.005 |
Level: CI-ERROR
Short Syntax: NDR.005 pkt source_ip_address -> destination_ip_address dsc rsn reason_code, nt Network ID
Long Syntax: NDR.005 Packet from source_ip_address for destination_ip_address discarded for reason reason_code,network Network ID
Description: An attempt was made to send the packet on the specified network, but it was not accepted for transmission on that network. The reason_code indicates why the packet was not accepted. If the reason was flow-control, an ICMP source quench will be sent to the sender, otherwise an ICMP destination unreachable will be sent.
Cause: Miscellaneous handler error. (Reason code 1.)
Action: Check for error messages from handler for network_name.
Cause: Output queue overflow, or other flow control. (Reason code 2.)
Action: Alleviate congestion.
Cause: Network down. (Reason code 3.)
Action: See why handler thinks network is down.
Cause: Dropped by handler to avoid looping, or bad broadcast. (Reason code 4.)
Action: Check configuration.
Cause: Host down. (Reason code 5.)
Action: See why handler thinks host is down.
