VLANs Spanning Multiple Switches

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.
