4.5.3 MSTP Instance
The MSTP combines VLANs and spanning tree together via VLAN-to-instance mapping table (VLAN-to-spanning-tree mapping).
By adding MSTP instances, it binds several VLANs to an instance to realize the load balance based on instances.
Only when the switches have the same MST region name, MST region revision and VLAN-to-Instance mapping table, the
switches can be regarded as in the same MST region.
The MSTP Instance function can be implemented on the Region Config, Instance Config and Instance Port Config pages;
the screen in Figure 4-5-10 appears.
