Scenario: Configuring a Virtual I/O Server by using VLAN tagging
Use this scenario to help you become familiar with creating a network by using VLAN tagging.
You are the system administrator responsible for planning and configuring the network in an environment with the Virtual I/O Server running. You would like to configure the network so that two logical subnets exist, with some logical partitions on each subnet.
The objective of this scenario is to configure multiple networks to share a single physical Ethernet adapter. Systems on the same subnet are required to be on the same VLAN, and therefore they have the same VLAN ID, which allows communication without having to go through the router. The separation in the subnets is achieved by ensuring that the systems on the two subnets have different VLAN IDs.
- The Hardware Management Console (HMC) is set up. For more information about installing and configuring the HMC, see Installing and configuring the Hardware Management Console.
- You understand the logical partitioning concepts. For more information, see Logical partitioning.
- The Virtual I/O Server logical partition is created and the Virtual I/O Server is installed. For instructions, see Installing the Virtual I/O Server and client logical partitions.
- You created the remaining AIX® or Linux logical partitions that you want added to the network configuration. (You cannot use VLAN tagging with IBM® i logical partitions.)
- You have an Ethernet switch and a router ready to add to the configuration.
- You have IP addresses for all logical partitions and systems that will be added to the configuration.
You cannot use VLAN in an Integrated Virtualization Manager environment.
The following figure shows the configuration that will be completed during this scenario.
Using the preceding figure as a guide, follow these steps.
You can configure the Shared Ethernet Adapter on the Virtual I/O Server logical partition with an IP address. This is required only for network connectivity to the Virtual I/O Server.
As the tagged VLAN network is being used, you must define additional VLAN devices over the Shared Ethernet Adapters before configuring IP addresses.
