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 165).
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 165).
3. On the STP Configuration page, enable the Spanning T
ree State option (see Configure the
STP settings and view the STP status on page 194).
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 196).
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 198).
6. Click the Apply button.
7. Select ports 1/0/1–1/0/5 (edge ports), and select Enable from the Fast Link menu.
