Digital Network Architecture Phase IV (DN)

This chapter describes Digital Network Architecture Phase IV (DN) messages. For information on message content and how to use the message, refer to the Introduction.

DN.001 

Level: UE-ERROR

Short Syntax: DN.001 event 4.0: Aged pkt loss; source_area. source_node -> destination_area. destination_node

Long Syntax: DN.001 event 4.0: Aged packet loss; packet from source_area. source_node to destination_area. destination_node

Description: A packet has had too many visits through routers going between the specified nodes. If return to sender was requested, the packet will be returned to the originator. Otherwise, it will be dropped.

Cause: The router's EXECUTOR MAXIMUM VISITS is too small.

Action: Increase EXECUTOR MAXIMUM VISITS to be larger the number of hops between the two most distant nodes in the network.

Cause: There is a temporary routing loop due to an unreachable node.

Action: Unless the problem is persistent, there should be no need for corrective action. Routing loops usually go away within a minute when a node goes down.

DN.002 

Level: CE-ERROR

Short Syntax: DN.002 event 4.1: Node unreach pkt loss; source_area. source_node -> destination_area. destination_node, cir number net network_name

Long Syntax: DN.002 event 4.1: Node unreachable packet loss; packet from source_area. source_node to destination_area. destination_node, circuit number network network_name

Description: Packet was received on the specified network for unreachable destination. If return to sender was requested, the packet will be returned to the originator. Otherwise, it will be dropped.

Cause: The originator is attempting to contact a non-existent node.

Action: If the originator supplied a host address, it should be corrected. If the originator supplied a host name, the node name to the address translation may be out of date. Use the DEFINE NODE "name" ADDRESS command on the originating node to correct the permanent database.

Cause: There is no route to the destination node in the routing database.

Action: Do a SHOW ACTIVE NODES to see if the destination node is reachable. Check the circuit(s) that could be used to reach this node.

Cause: There is no route to the destination area in the routing database.

Action: Do a SHOW ACTIVE AREA to see if the area of the destination node is reachable. Check the circuit(s) that could be used to reach this area.

DN.003 

Level: UI-ERROR

Short Syntax: DN.003 event 4.2: Node out-of-range pkt loss; source_area. source_node -> destination_area. destination_node, cir number net network_name

Description: Packet was received on the specified network for node address beyond EXECUTOR MAXIMUM ADDRESS. If return to sender was requested, the packet will be returned to the originator. Otherwise, it will be dropped.

Cause: EXECUTOR MAXIMUM ADDRESS set too low.

Action: Increase EXECUTOR MAXIMUM ADDRESS.

Cause: Destination node's EXECUTOR NODE ADDRESS set too high.

Action: Decrease destination node's EXECUTOR NODE ADDRESS.

Cause: The originator is attempting to contact a non-existent node, which also has too high an address.

Action: If the originator supplied a host address, it should be corrected. If the originator supplied a host name, the node name to address translation may be out of date. Use the DEFINE NODE "name" ADDRESS command on the originating node to correct the permanent database.

DN.004 

Level: UE-ERROR

Short Syntax: DN.004 event 4.3: Ovsize pkt loss; source_area. source_node -> destination_area. destination_node, cir number net network_name

Description: Packet was received that is larger than the blocksize of the output circuit chosen to the destination. The packet will be dropped.

Cause: Originating host has a larger EXECUTOR BUFFER SIZE than the receiving host can accept.

Action: Correct EXECUTOR BUFFER SIZE on originating host.

Cause: Intervening circuit has too small a packet size.

Action: Ensure that originating host's EXECUTOR BUFFER SIZE is smaller than the circuit with the lowest packet size. (Since Ethernet has the smallest blocksize, this is not likely.)

DN.104 

Level: UE-ERROR

Short Syntax: DN.104 Verif fail; source_node, cir number net network_name

Long Syntax: DN.104 Verification failure; from source_node, circuit number network network_name

Description: Verification failure. The router detected an error in the Verification Message.

DN.105 

Level: UE-ERROR

Short Syntax: DN.105 Hlo/tst fail; source_node, cir number net network_name

Long Syntax: DN.105 Error detected in processing Hello/Test Message; from source_node, circuit number network network_name

Description: The router detected an error in processing the Hello/Test Message. The forwarder drops the packet.

DN.106 

Level: ALWAYS

Short Syntax: DN.106 Hlo/Tst Msg rcvd; source_node, cir number net network_name

Long Syntax: DN.106 Received Hello/Test Message; from source_node, circuit number network network_name

Description: The router received a Hello/Test Message from a neighbor.

DN.107 

Level: UI-ERROR

Short Syntax: DN.107 no buffer for Init Msg on cir number net network_name

Long Syntax: DN.107 No buffer to build Initialization Message to send on circuit number network network_name

Description: No packet buffer was available to construct and send an Initialization Message.

Cause: Severe packet buffer shortage.

Action: Check memory statistics in GWCON to verify packet buffer level. If possible, make routing tables smaller. To do this in DECnet, minimize the number of adjacencies allowed. (Configure EXECUTOR MAXIMUM BROADCAST ROUTERS and EXECUTOR MAXIMUM BROADCAST NONROUTERS to minimum appropriate values.) If the router cannot make the routing tables smaller, increase memory size.

Cause: Traffic peak using all available buffers.

Action: If this message occurs infrequently, this is the problem.

DN.108 

Level: UI-ERROR

Short Syntax: DN.108 Snd fail for Init Msg; cir number net network_name

Long Syntax: DN.108 Send failed for Initialization Message on circuit number network network_name

Description: The transmission of a router Initialization Message failed on the specified circuit. Occasional occurrences of this will not disrupt the protocol, but continuing occurrences will disrupt the protocol.

DN.109 

Level: ALWAYS

Short Syntax: DN.109 snd Init Msg; cir number net network_name

Long Syntax: DN.109 Sending Initialization Message on circuit number network network_name

Description: The router is sending an Initialization Message on the indicated circuit.

DN.110 

Level: UI-ERROR

Short Syntax: DN.110 Snd fail for Verif Msg; cir number net network_name

Long Syntax: DN.110 Send failed for Verification Message on circuit number network network_name

Description: The transmission of a router Verification Message failed on the specified circuit.

DN.111 

Level: ALWAYS

Short Syntax: DN.111 snd Verif Msg; cir number net network_name

Long Syntax: DN.111 Sending Verification Message on circuit number network network_name

Description: The router is sending a Verification Message on the indicated circuit.

DN.112 

Level: UI-ERROR

Short Syntax: DN.112 Snd fail for Hlo/TstMsg; cir number net network_name

Long Syntax: DN.112 Send failed for Hello/Test Message on circuit number network network_name

Description: The transmission of a router Hello/Test Message failed on the specified circuit.

DN.113 

Level: ALWAYS

Short Syntax: DN.113 snd Hlo/Tst Msg; cir number net network_name

Long Syntax: DN.113 Sending Hello/Test Message on circuit number network network_name

Description: The router is sending a Hello/Test Message on the indicated circuit.

DN.114 

Level: UI-ERROR

Short Syntax: DN.114 x25 reg fail

Long Syntax: DN.114 Registration with X25 service failed

Description: The forwarder could not register with X.25 services on the interface.

DN.115 

Level: UI-ERROR

Short Syntax: DN.115 call req to x25 fail; intf number net network_name

Long Syntax: DN.115 Call request to X25 service failed on interface number network network_name

Description: The forwarder's call request to X.25 services failed on the indicated network.
