Configuring VLANs 51Figure 39 Tagged VLAN ConfigurationTo set up the configuration shown in Figure 39, do thefollowing:1 Create VLAN2 on both Switch 1 and Switch 2. Youneed not create VLAN1 since it exists by default.2 On Switch 1, set the ports that you want to be part ofVLAN2 to Untagged. Set one port (for example, port16) to Tagged.Click Apply.3 On Switch 2, set the ports that you want to be part ofVLAN2 to Untagged. Set one port (for example, port 8)to Tagged.Click Apply.4 Connect the Tagged port on Switch 1 (in this example,port 16) to the Tagged port on Switch 2 (in thisexample, port 8).Those ports on Switch 1 that are members of VLAN2can now communicate with those ports on Switch 2that are members of VLAN2.Spanning TreeSpanning tree is a bridge-based system for providingfault tolerance on networks and can be used to detectand disable network loops. The spanning tree ensuresthat the optimal path is maintained between spanningtree-compliant networked devices by:■ Disabling redundant paths when the main paths areoperational.■ Enabling redundant paths if the main paths fail.Spanning tree uses a distributed algorithm to select abridging device that serves as the root of the spanning
