GS752TXS and GS728TXS Smart Switches
The combination of VID to FID and then FID to MSTI allocation defines a mapping of VIDs to
spanning tree instances, represented by the MST Configuration Table.
spanning tree instances, represented by the MST Configuration Table.
With this allocation we ensure that every VLAN is assigned to one and only one MSTI. The
CIST is also an instance of spanning tree with a MSTID of 0.
CIST is also an instance of spanning tree with a MSTID of 0.
An instance can occur that has no VIDs allocated to it, but every VLAN must be allocated to
one of the other instances of spanning tree.

The portion of the active topology of the network that connects any two bridges in the same
MST Region traverses only MST bridges and LANs in that region, and never Bridges of any
kind outside the Region, in other words connectivity within the region is independent of
external connectivity.

Sample MSTP Configuration
This example shows how to create an MSTP instance from the GS752TXS/GS728TXS
switch. The example network has three different GS752TXS/GS728TXS switches that serve
different locations in the network. In this example, ports g1–g5 are connected to host
stations, so those links are not subject to network loops. Ports g6–g8 are connected across
switches 1, 2, and 3.

Perform the following procedures on each switch to configure MSTP:
1.
Use the VLAN Configuration screen to create VLANs 300 and 500 (see
2.
Use the VLAN Membership screen to include ports g1–g8 as tagged (T) or untagged (U)
members of VLAN 300 and VLAN 500 (see
3.
From the STP Configuration screen, enable the Spanning Tree State option (see
