You cannot enable BPDU tunneling on a member port of a service loopback group. Before enabling BPDU tunneling for DLDP, EOAM, GVRP, HGMP, LLDP, or STP on a port, disable the protocol on the port first. To enable BPDU tunneling for PVST (which is a spanning tree protocol) on a port, disable STP first and then enable BPDU tunneling for STP on the port. Do not enable BPDU tunneling for DLDP, EOAM, LACP, LLDP, PAGP, or UDLD on the member port of a Layer 2 aggregation group.
