vrPpSrsgStpTypeProv
Virtual Router Passport Srsg Stp Type Prov
This attribute specifies the type of spanning tree protocol the port is participating in. A bridge port could participate in either the ieee8021 spanning tree protocol or the dec spanning tree protocol. If the value of the attribute protocolSpec in the SpanningTreeProtocol component, provisioned under the TransparentBridge component is in conflict with the value of this attribute, the value of the protocolSpec attribute will prevail. Prevailing stp type is reflected in the value of the attribute stpTypeOper.
