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 1/0/1–1/0/5 are connected to host stations, so those links are not subject to network
loops. Ports 1/0/6–1/0/8 are connected across switches 1, 2, and 3.
Figure 4. MSTP example 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 151).
2. On the VLAN Membership page, include ports 1/0/1–1/0/8 as tagged (T) or untagged (U)
members of
VLAN 300 and VLAN 500 (see
Configure VLAN settings on page 151).
3. On the STP Configuration page, enable the Spanning Tree State option (see
Configure the
STP settings and view the STP status on page 179).
Use the default values for the rest of the STP configuration settings. By default, the STP
operation mode is MSTP and the configuration name is the switch MAC address.
4. On the CST Configuration page, set the bridge priority value for each of the three switches
to force
Switch 1 to be the root bridge:
• Switch 1. 4096
• Switch 2. 12288
• Switch 3. 20480
Note: Bridge priority values are multiples of 4096.
