Smart Managed Pro Switches MS510TX and MS510TXPP
Configuration Examples User Manual347
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 an MSTID of 0.
VIDs might be not be allocated to an instance, 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
.
MSTP Example Configuration
This example shows how to create an MSTP instance from the switch. The example network
includes three different switches that serve different locations in the network. In this example,
ports g1–mg5 are connected to host stations, so those links are not subject to network loops.
Ports mg6–mg7 are connected across switches 1, 2, and 3.

Figure 2. MSTP sample configuration
Perform the following procedures on each switch to configure MSTP:
1. On
the VLAN Configuration page, create VLANs 300 and 500 (see Configure VLAN
Settings on page 97).
