MSTI Mapping Configuration Parameters:
Items Description
Configuration
Identification The name identifying the VLAN to MSTI mapping. Bridges must share the name and revision
(see below), as well as the VLAN-to-MSTI mapping configuration in order to share spanning
trees for MSTI's (Intra-region). The name is at most 32 characters.
Configuration Revision The revision of the MSTI configuration named above. This must be an integer between 0
and 65535.
MSTI The bridge instance. The CIST is not available for explicit mapping, as it will receive the
VLANS not explicitly mapped.
VLANs Mapped The list of VLANs mapped to the MSTI. The VLANs can be given as a single (xx, xx being between
1 and 4094) VLAN, or a range (xx-yy), each of which must be separated with comma
and/or space. A VLAN can only be mapped to one MSTI. An unused MSTI should just be left
empty (not having any VLANs mapped to it). Example: 2,5, 20-40.
Spanning Tree MSTI Priorities
When implementing a Spanning Tree protocol on the switch t he CIST is the default instance which is always active.
This is because it controls the bridge priority. Lower numeric values have higher priority. The bridge priority plus the MSTI
instance number, concatenated with the 6-byte MAC address of the switch forms a Bridge Identifier.
This section allows the user to inspect and configure the current STP MSTI bridge instance priority configurations.
To configure MSTI Priorities in the web interface:

Click Configuration / Spanning Tree / MSTI Priorities

Set the Priority, maximum is 240. Default is 128.

Click Apply and click the Save icon in the upper right corner to save the settings. Click Reset to cancel. The page
will return to previously saved settings.
