A VTP ring number configuration conflict notification is generated if, and only at the time when, a device learns of a conflict between: a) the ring number (vtpVlanPortLocalSegment) being used on a token ring segment attached to the port identified by ifIndex, and b) the VTP-obtained ring number (vtpVlanRingNumber) for the VLAN identified by vtpVlanIndex. When such a conflict occurs, the bridge port is put into an administrative down position until the conflict is resolved through local/network management intervention. This notification is only applicable to VLANs of type 'tokenRing'.
