VLANs 42
Multiple VLANS with tagging
The following figure shows only those switch port to server links that must be configured for the example. While not
shown, all other server links remain set at their default settings.
Figure 7 Multiple VLANs with VLAN tagging
The features of this VLAN are described in the following table:
NOTE: The port numbers specified in these illustrations may not directly correspond to the physical port
configuration of your switch model.
Table 9 Multiple VLANs with tagging
Component Description
Switch 1 Switch 1 is configured for VLANS 1, 2, and 3. Port 1 is tagged to accept traffic from
VLANs 1 and 2. Ports 17 and 18 are tagged members of a trunk that accepts traffic from
VLANs 1 and 3. Port 20 is tagged to accept traffic from VLANs 1, 2, and 3. Port 23 is an
untagged member of VLAN 2.
Switch 2 Switch 2 is configured for VLANS 1, 3, and 4. Port 2 is tagged to accept traffic from
VLANS 3 and 4. Port 4 is configured only for VLAN 3, so VLAN tagging is off. Port 20 is
tagged to accept traffic from VLANs 1 and 3. Port 23 is an untagged member of VLAN 4.
CPU Blade Server #1 This high-use blade server needs to be accessed from all VLANs and IP subnets. The
server has a VLAN-tagging adapter installed with VLAN tagging turned on.
One adapter is attached to one of the switch's 10/100/1000 Mbps ports, that is
configured for VLANs 1 and 2. One adapter is configured for VLANs 3 and 4.
Because of the VLAN tagging capabilities of both the adapter and the switch, the server
is able to communicate on all four VLANs in this network while maintaining broadcast
separation among all four VLANs and subnets.
