Using the BayStack 350 10/100/1000 Series Switch
Because there is only one link between the two switches, the Spanning Tree Protocol (STP) treats this configuration as any other
VLANS Spanning Multiple Untagged Switches
Figure 1-15 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 1-15. 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.
