LANNING

2-4

When you expand port-based VLANs across several switches, you

need to make a separate connection for each VLAN group. This

approach is, however, inconsistent with the Spanning Tree

Protocol, which can easily segregate ports that belong to the same

VLAN. When VLANs cross separate switches, it is therefore better

to use VLAN tagging. This allows you to assign multiple VLAN

groups to the “trunk” ports (that is, tagged ports) connecting

different switches.

Figure 2-3. Making VLAN Connections

Note: When connecting to a switch that does not support IEEE

802.1Q VLAN tags, use untagged ports.
