Defining MSTP Instance to VLAN
MSTP maps VLANs into STP instances. Packets assigned to various VLANs are
transmitted along different paths within
Multiple Spanning Tree Regions (MST
Regions). Regions are one or more Multiple Spanning Tree bridges by which
frames can be transmitted. In configuring MSTP, the MST region to which the
device belongs is defined. A configuration consists of the name, revision, and
region to which the device belongs.
The VLAN screen enables mapping VLANs to MSTP Instances.
STEP 1 Click Bridging > Spanning Tree > MSTP > Instance to VLAN. The Instance to VLAN
Page
opens:
Instance to VLAN Page
The
Instance to VLAN Page contains the following fields:
• VLAN — Indicates the VLAN for which the MSTP instance ID is defined.
• Instance ID (0-15) — Indicates the MSTP instance ID assigned to the VLAN. The
possible field range is 0-15.
STEP 2 Map the VLANs to Instance IDs.
STEP 3 Click Apply. The MSTP VLAN mapping is defined, and the device is updated.
