z If both GVRP and MSTP are enabled on a device at the same time, GVRP packets will be
forwarded along the CIST. Therefore, if you wish to advertise a certain VLAN within the network
through GVRP in this case, make sure that this VLAN is mapped to the CIST (MSTI 0) when
configuring the VLAN-to-MSTI mapping table. For the detailed information of GVRP, refer to GVRP
Configuration of the Access Volume.
z MSTP is mutually exclusive with any of the following functions on a port: service loopback, RRPP,
Smart Link, and BPDU tunnel.
z Configurations made in Layer-2 aggregate interface view can take effect only on the aggregate
interface; configurations made on an aggregation member port can take effect only after the port is
removed from the aggregation group. For detailed information about link aggregation, refer to Link
Aggregation Configuration in the Access Volume.
z After you enable MSTP on a Layer-2 aggregate interface, the system performs MSTP calculation
on the Layer-2 aggregate interface but not on the aggregation member ports. The MSTP enable
state and forwarding state of each selected port in an aggregation group is consistent with those of
the corresponding Layer-2 aggregate interface.
z Though the member port of an aggregation group does not participate in MSTP calculation, the
port still reserves its MSTP configurations for participating MSTP calculation after leaving the
aggregation group.
