What is multiChassisTrapStpBlockingVlanList?

Lists up to 16 VLANs whose Spanning Tree Protocol (STP) state on the Virtual Fabric Link (VFL) is currently blocking, meaning those VLANs are not forwarding traffic over the VFL. This data is included in trap notifications to help diagnose STP-related connectivity issues in a multi-chassis environment.
