VLANs 43
Table 9 Multiple VLANs with tagging
Component Description
CPU Blade Server #2 This blade server belongs to VLAN 3. The port that the VLAN is attached to is configured
only for VLAN 3, so VLAN tagging is off.
PC #1 This PC is a member of VLAN 2 and 3. Via VLAN 2, it can communicate with Server 1,
PC 3, and PC 5. Via VLAN 3, it can communicate with Server 1, Server 2, and PC 4.
PC #2 This PC is a member of VLAN 4, and can only communicate with Server 1.
PC #3 This PC is a member of VLAN 1 and VLAN 2. Via VLAN 1, it can communicate with
Server 1 and PC 5. Via VLAN 2, it can communicate with Server 1, PC 1, and PC 5.
PC #4 This PC is a member of VLAN 3, and it can communicate with Server 1, Server 2, and
PC 1.
PC #5 This PC is a member of both VLAN 1 and VLAN 2. Via VLAN 1, it can communicate with
Server 1 and PC 3. Via VLAN 2, it can communicate with Server 1, PC 1, and PC 3. The
Layer 2 switch port to which it is connected is configured for both VLAN 1 and VLAN 2
and has tagging enabled.
NOTE: All PCs connected to a tagged port must have an Ethernet adapter with VLAN-tagging capability
installed.
