Using the BayStack 410-24T 10BASE-T Switch

Because there is only one link between the two switches, the Spanning Tree Protocol (STP) treats this configuration as any other switch-to-switch connection. For this configuration to work properly, both switches must support the 802.1Q tagging protocol.

VLANs Spanning Multiple Untagged Switches

Figure 1-23 shows VLANs spanning multiple untagged switches. In this configuration switch S2 does not support 802.1Q tagging and a single switch port on each switch must be used for each VLAN.

For this configuration to work properly, spanning tree participation must be set to Disabled because the STP is not supported across multiple LANs.

Figure 1-23. VLANs Spanning Multiple Untagged Switches

When the STP is enabled on these switches, only one link between each pair of switches will be forwarding traffic. Because each port belongs to only one VLAN at a time, connectivity on the other VLAN will be lost. Exercise care when configuring the switches to ensure that the VLAN configuration does not conflict with spanning tree configuration.
