Introduction to the BayStack 410-24T Switch

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.

VLANs Spanning Multiple 802.1Q Tagged Switches

Figure 1-22 shows VLANs spanning two BayStack 410-24T switches. 802.1Q 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.
