Table 10 Multiple VLANs with tagging
Component Description
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 Gbps 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.
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. Using 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. Using VLAN 1, it can communicate with
Server 1 and PC 5. Using 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. Using VLAN 1, it can communicate with
Server 1 and PC 3. Using 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.
Configuring the example network
These examples describe how to configure ports and VLANs on Switch 1 and Switch 2.
Configuring ports and VLANs on Switch 1 (CLI example)
To configure ports and VLANs on Switch 1, do the following:
1. On Switch 1, enable VLAN tagging on the necessary ports.
Main# /cfg/port 1
>> Port 1# tag e (Select port 1: connection to server 1)
Current VLAN tag support: disabled
New VLAN tag support: enabled (Enable tagging)
Port 1 changed to tagged.
Main# /cfg/port 18 (Select uplink port 18)
>> Port 18# tag e (Enable tagging)
Current VLAN tag support: disabled
New VLAN tag support: enabled
Port 18 changed to tagged.
>> Port 18# apply (Apply the port configurations)
