Short Syntax: DVM.001 Unknown DVMRP code from IP_source, code= message_code
Long Syntax: DVM.001 Received unknown DVMRP code from IP_source, code= message_code

Level: P-TRACE
Short Syntax: DVM.021 Packet rcvd from mis/unconfigured tunnel source_IP_address
Long Syntax: DVM.021 Packet received from mis/unconfigured tunnel source_IP_address

| DVM.022 |
Level: C-INFO
Short Syntax: DVM.022 Snt PRUNE (src= source_net grp= group_address life= prune_lifetime) to neighbor_IP_address, VIF= VIF_index
Long Syntax: DVM.022 Sent PRUNE (source= source_net group= group_address, lifetime= prune_lifetime) to neighbor_IP_address, VIF= VIF_index
Description: Sent a DVMRP PRUNE message to the specified IP address on the specified virutual interface. The packet contained the given source network, group address, and prune lifetime, in seconds. A PRUNE is being sent because this router has determined that receiving this traffic would be wasteful since this router will just discard it. The PRUNE informs the neighbors on the interface that multicast traffic, destined for this group address and sent from this source network, should not be forwarded to this router for next prune_lifetime number of seconds. Large amounts of wasteful multicast traffic are avoided as PRUNE information is exchanged among the routers forming the multicast DVMRP internet.
| DVM.023 |
Level: U-INFO
Short Syntax: DVM.023 Snt GRAFT (src= source_net grp= group_address) to neighbor_IP_address, VIF= VIF_index
Long Syntax: DVM.023 Sent GRAFT (source= source_net group= group_address) to neighbor_IP_address, VIF= VIF_index
Description: Sent a DVMRP GRAFT message to the specified IP address on the specified virtual interface. The packet contained the given source network and group address. A GRAFT is being sent because this router has determined that receiving this multicast traffic, which was previously determined to be wasteful, is now no longer wasteful. The GRAFT informs the neighbors on the interface to cancel any previous PRUNE, if any, that the neighbor may have in effect for the specified group address, source network from this router.
| DVM.024 |
Level: C-TRACE
Short Syntax: DVM.024 Snt GRAFT ACK (src= source_net grp= group_address) to neighbor_IP_address, VIF= VIF_index
Long Syntax: DVM.024 Sent GRAFT ACK (source= source_net group= group_address) to neighbor_IP_address, VIF= VIF_index
Description: Sent a DVMRP GRAFT ACK message to the specified IP address on the specified virtual interface. The packet contained the given source network and group address. A GRAFT ACK message is used to acknowledge a GRAFT message.
| DVM.025 |
Level: C-INFO
Short Syntax: DVM.025 Rec PRUNE (src= source_net grp= group_address life= prune_lifetime) frm neighbor_IP_address, VIF= VIF_index, act= action_taken
Long Syntax: DVM.025 Rec PRUNE (source= source_net group= group_address lifetime= prune_lifetime) frm neighbor_IP_address, VIF= VIF_index action= action_taken
Description: Received a PRUNE, containing the displayed source, group, and lifetime values, from an IP neighbor on a virutual interface. The PRUNE was accepted. The only possible action taken values is: (1) "accepted", meaning that the PRUNE was accepted.
| DVM.026 |
Level: UI-ERROR
Short Syntax: DVM.026 Rec PRUNE (src= source_net grp= group_address life= prune_lifetime) frm neighbor_IP_address, VIF= VIF_index, rej= action_taken
Long Syntax: DVM.026 Rec PRUNE (source= source_net group= group_address lifetime= prune_lifetime) frm neighbor_IP_address, VIF= VIF_index reject= action_taken
Description: Received a PRUNE, containing the displayed source, group, and lifetime values, from an IP neighbor on a virutual interface. The PRUNE was not accepted because of the displayed reason. Possible action taken values are: (1) "pkt trunc" - the PRUNE packet was too short, (2) "unknown nbr" - the sender was not a known DVMRP neighbor, (3) "unreach src net" - the router can not route to the source_net, (4) "no mem for Mfcache" - the router had no memory to build a multicast forwarding entry, (5) "no DVMRP rte" - the router has no DVMRP route to the this source_net, (6) "not from dependent nbr" - the source_net was not a downstream neighbor to which the router forwards, (7) "no mem for group" - the router had no memory to build a group entry, (8) "no mem for prune" - the router had no memory to build a prune entry,
| DVM.027 |
Level: UI-ERROR
Short Syntax: DVM.027 No mem for prune mgnt, grp neighbor_IP_address
Long Syntax: DVM.027 No memory for prune management, group neighbor_IP_address
Description: There was no room to allocate a group pr prune data structure to manage the pruning and grafting of the specified group. Some functinonaly for prune and graft logic will be lost until memory can be allocated. If this message is not persistent, then the situation has recovered; otherwise DVMRP functionality is being lost.
| DVM.028 |
Level: UI-ERROR
Short Syntax: DVM.028 No buf for msg message_code, frm src_IP
Long Syntax: DVM.028 No buffer for message message_code, frm src_IP
Description: There was io buffer available to send a DVMRP message. This means that a DVMRP message that should have been sent is not sent. If this message is not persistent, the situation has recovered; otherwise DVMRP functionality is being lost.
| DVM.029 |
Level: C-INFO
Short Syntax: DVM.029 Rec GRAFT (src= source_net grp= group_address) frm neighbor_IP_address, VIF= VIF_index, act= action_taken
Long Syntax: DVM.029 Rec GRAFT (source= source_net group= group_address) frm neighbor_IP_address, VIF= VIF_index action= action_taken
Description: Received a GRAFT, containing the displayed source and group values, from an IP neighbor on a virutual interface. Possible action taken values are: (1) "accepted" - the GRAFT matched a PRUNE in the router's prune database, (2) "pkt trunc" - the PRUNE packet was too short, (3) "unknown nbr" - the sender was not a known DVMRP neighbor, (4) "unreach src net" - the router can not route to the source_net, (5) "no mem for Mfcache" - the router had no memory to build a multicast forwarding entry, (6) "no DVMRP rte" - the router has no DVMRP route to the this source_net, (7) "not from dependent nbr" - the source_net was not a downstream neighbor to which the router forwards, (8) "no group found" - the router did not find a group entry for this group. group entry, (9) "no prune found" - the router did not find a matching prune. prune entry, Note that although many of these cases sound unsuccessful, a GRAFT ACK is sent for all of these except "pkt trunc" and "unknown nbr".
| DVM.030 |
Level: C-INFO
Short Syntax: DVM.030 Rec GRAFT ACK (src= source_net grp= group_address) frm neighbor_IP_address, VIF= VIF_index, act= action_taken
Long Syntax: DVM.030 Rec GRAFT ACK (source= source_net group= group_address) frm neighbor_IP_address, VIF= VIF_index action= action_taken
Description: Received a GRAFT ACK, containing the displayed source and values, from an IP neighbor on a virutual interface. Possible action taken values are: (1) "accepted" - the GRAFT ACK successfully matched a GRAFT on this router that needed acknowledgment, (2) "pkt trunc" - the GRAFT ACK was too short, (3) "unknown nbr" - the sender was not a known DVMRP neighbor, (4) "unreach src net" - the router can not route to the source_net, (5) "no mem for Mfcache" - the router had no memory to build a multicast forwarding entry, (6) "no DVMRP rte" - the router has no DVMRP route to the this source_net, (7) "no group found" - the router did not find a group entry for this group. (8) "not upstream nbr" - the GRAFT ACK was not from the upstream neighbor. The normal case is accepted. But other values can norally occur as tables change dynamically. If this message action persistently is not the accepted case, there may be a protocol problem. The problem is probably on the router sending the GRAFT ACK.
| DVM.031 |
Level: C-TRACE
Short Syntax: DVM.031 Unsupported Default Route from neighbor_IP_address, VIF= VIF_index
Long Syntax: DVM.031 Received a default route entry, which is not supported, from neighbor_IP_address, VIF= VIF_index
Description: The router received a default route advertisement on the specified virtual interface. This DVMRP implementation does not support default routes for multicast.
