If GVRP and MSTP are both 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 you
configure the VLAN-to-instance mapping table. For the detailed information of GVRP, refer to
GVRP Configuration of the Access Volume.
MSTP is mutually exclusive with any of the following functions on a port: service loopback, RRPP,
Smart Link, and BPDU tunnel.
Configurations made in system view take effect globally; configurations made in Ethernet interface
view take effect on the current interface only; configurations made in port group view take effect on
all member ports in the port group; configurations made in Layer 2 aggregate interface view 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.
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.
Though the member ports of an aggregation group do not participate in MSTP calculation, the ports
still reserve its MSTP configurations for participating MSTP calculation after leaving the
aggregation group.
