, 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 virtual 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.

) 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.
- Level:
- C-TRACE
- Short Syntax:
- DVM.024 Snt GRAFT ACK (src= source_net

) 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.

, VIF= VIF_index
reject= action_taken
- Description:
- Received a PRUNE, containing the displayed source, group, and
lifetime values, from an IP neighbor on a virtual 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,

- 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.

- 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.

- 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 virtual 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".

- 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 virtual 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.
- Level:
- UI-ERROR
- Short Syntax:
- DVM.031 Too many encaps, drop pkt
- Long Syntax:
- DVM.031 Too many encapsulations, dropping packet
- Description:
- The tunnel header can not be prepended to the packet due to
insufficient header space.
- Cause:
- The packet is passing through multiple tunnels.
- Action:
- Reconfigure to guarantee packets only pass through one tunnel.
