Enable MSTP on the device
Enable MSTP on a port
Only after MSTP is enabled on the device will other configurations take effect. Before
enabling MSTP, you can configure the related parameters of the device and Ethernet
ports, which will take effect upon enabling MSTP and stay effective even after resetting
MSTP. The check command can show the region parameters yet to take effect. The
display active-region-configuration command shows the parameters configured
before MSTP is enabled. For those configured after MSTP is enabled, you can use the
related display commands to display. For detailed information, refer to the "Display and
Debug MSTP" section. .
You do not have to perform all the mentioned tasks to configure MSTP. Many of them
are designed to adjust the MSTP parameters provided with default values. You can
configure these parameters per the actual conditions or simply take the defaults. For
detail information, refer to the task description or the Command Manual.
Note:
When GVRP and MSTP startup on the switch simultaneously, GVRP packets will
propagate along CIST which is a spanning tree instance. In this case, if you want to
issue a certain VLAN through GVRP on the network, you should make sure that the
VLAN is mapped to CIST when configuring the VLAN mapping table of MSTP.
CIST is spanning tree instance 0.
