dvmrpNeighborLoss
Module: DVMRP-STD-MIB
OID (symbolic): DVMRP-STD-MIB::dvmrpNeighborLoss
OID (numeric): 1.3.6.1.3.62.1.1.7.1
Node type: NOTIFICATION-TYPE
Description: A dvmrpNeighborLoss trap signifies the loss of a 2-way adjacency with a neighbor. This trap should be generated when the neighbor state changes from active to one-way, ignoring, or down. The trap should be generated only if the router has no other neighbors on the same interface with a lower IP address than itself.
What is dvmrpNeighborLoss?
This OID is an alert that fires when the router loses its active connection to a neighboring router in the multicast network. It indicates that direct communication with that neighbor has failed, potentially breaking multicast traffic paths. An operator would receive this alert when investigating why multicast streams stopped reaching certain parts of the network.
Examples
Send this trap to an SNMP manager — replace <manager> with the IP or hostname of your monitoring server (SNMPv2c):
snmptrap -v2c -c public <manager> '' DVMRP-STD-MIB::dvmrpNeighborLoss snmptrap -v2c -c public <manager> '' 1.3.6.1.3.62.1.1.7.1
Listen for incoming traps on the manager host (-f keeps it in the foreground, -Lo prints to stdout — useful for testing):
snmptrapd -f -Lo -c /dev/null authCommunity log public
Example snmptrapd log entry:
zoo11-linux.zoo [UDP: [192.168.30.111]:62424->[192.168.30.10]:162]: DISMAN-EVENT-MIB::sysUpTimeInstance = Timeticks: (280583640) 32 days, 11:23:56.40 SNMPv2-MIB::snmpTrapOID.0 = OID: DVMRP-STD-MIB::dvmrpNeighborLoss
SNMPv3 example:
snmptrap -v3 -l authPriv -u snmpv3user -a SHA -A "AuthPass1" -x AES -X "PrivPass1" <manager> '' DVMRP-STD-MIB::dvmrpNeighborLoss
