Figure 2. 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 the VLAN
Settings on page 140).
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 the VLAN Settings on page 140).
3. On the STP Configuration page, enable the Spanning Tree State option (see
Configure the
STP settings and view the STP status on page 164).
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.
If you do not specify a root bridge and all switches are assigned the same bridge priority
value, the switch with the lowest MAC address is elected as the root bridge (see
Configure the CST settings on page 166).
5. On the CST Port Configuration page, select ports 1/0/1–1/0/8 and select Enable from the
STP Status menu (see
Configure the CST port settings on page 167).
6. Click the Apply button.
