Figure 31 Tagged VLAN Configuration
To set up the configuration shown in Figure 31, do the
following:
1 Create VLAN2 on both Switch 1 and Switch 2. You
need not create VLAN1 since it exists by default.
2 On Switch 1, set the ports that you want to be part of
VLAN2 to Untagged. Set one port (for example, port
16) to Tagged.
Click Apply.
3 On Switch 2, set the ports that you want to be part of
VLAN2 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 this
example, port 8).
Those ports on Switch 1 that are members of VLAN2
can now communicate with those ports on Switch 2
that are members of VLAN2.
Spanning Tree
Spanning tree is a bridge-based system for providing
fault tolerance on networks and can be used to detect
and disable network loops. The spanning tree ensures
that the optimal path is maintained between spanning
tree-compliant networked devices by:
■ Disabling redundant paths when the main paths are
operational.
■ Enabling redundant paths if the main paths fail.
Spanning tree uses a distributed algorithm to select a
bridging device that serves as the root of the spanning
tree network. The bridging device, known as the Root
