You can use VLANs to segment a network within a switch. When connecting 
multiple switches, it is possible to connect users of one VLAN with users of that 
same VLAN in another switch. However, the configuration guidelines depend on 
whether both switches support 802.1Q tagging.

With 802.1Q tagging enabled on a port for a VLAN, all frames leaving the port for 
that VLAN are marked as belonging to that specific VLAN. Users can assign 
specific switch ports as members of one or more VLANs that span multiple 
switches, without interfering with the spanning tree protocol.

tagging is enabled on S1, port 2 and on S2, port 1 for VLAN 1 and VLAN 2. Both 
ports are tagged members of VLAN 1 and VLAN 2.
