VLAN to MST Instance Page
The
Spanning Tree Instance (MSTI). For devices to be in the same region, they must
have the same mapping of VLANs to MSTIs.
The same MSTI can be mapped with more than one VLAN, but each VLAN can only
have one MST Instance attached to it.
Configuration on this page (and all of the MSTP pages) applies if the system STP
mode is MSTP.
Up to seven MST instances can be defined on Cisco Small Business 300 Series
switches. For those VLANs that are not explicitly mapped to one of the MST
instances, the switch automatically maps them to the CIST (Core and Internal
Spanning Tree) instance. The CIST instance is MST instance 0.
To map VLANs to MST Instances:
Click Spanning Tree > VLAN to MST Instance. The
displays.
The VLAN to MST Instance page contains the following fields:
•
MST Instance ID—All MST instances are displayed.
•
VLANs—All VLANs belonging to the MST instance are displayed.
