vlanTrunkPortOutJoins
Module: CISCO-VTP-MIB
OID (symbolic): CISCO-VTP-MIB::vlanTrunkPortOutJoins
OID (numeric): 1.3.6.1.4.1.9.9.46.1.6.1.1.8
Node type: OBJECT-TYPE
Type: Counter32
Access: read-only
Description: The number of VTP Join messages sent on this trunk port.
What is vlanTrunkPortOutJoins?
This read-only Counter32 object counts how many VTP Join messages this device has sent out on a specific trunk port, part of the VTP pruning mechanism used to advertise which VLANs are actively needed downstream. An administrator monitors this to confirm the switch is actively participating in pruning-related join signaling on that trunk. For example, a trunk port with a flat vlanTrunkPortOutJoins count despite VLANs coming and going downstream might indicate a pruning signaling problem on that port.
