Use the VLAN Configuration screen to create VLANs 300 and 500 (see VLAN Configuration on page 137). 2. Use the VLAN Membership screen to include ports 1/0/1 - 1/0/8 as tagged (T) or untagged (U) members of VLAN 300 and VLAN 500 (see VLAN Configuration on page 137). 3. From the STP Configuration screen, enable the Spanning Tree State option (see STP Configuration on page 158). 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.

If you do not specify a root bridge and all switches have the same Bridge Priority value, the switch with the lowest MAC address is elected as the root bridge (see CST Configuration on page 162). 5. From the CST Port Configuration screen, select ports 1/0/1 - 1/0/8 and select Enable from the STP Status menu (see CST Port Configuration on page 164). 6. Click APPLY. 375
