Scenario: Configuring a Virtual I/O Server without VLAN tagging
Use this scenario to help you become familiar with creating a network without 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 want to configure a single logical subnet on the system that communicates with the switch.
The objective of this scenario is to configure the network where only Port Virtual LAN ID (PVID) is used, the packets are not tagged, and a single internal network is connected to a switch. There are no virtual local area networks (VLAN) tagged ports set up on the Ethernet switch, and all virtual Ethernet adapters are defined using a single default PVID and no additional VLAN IDs (VIDs).
- The Hardware Management Console (HMC) was set up. For more information about Installing and configuring the Hardware Management Console , see Installing and configuring the Hardware Management Console.
- You understand the partitioning concepts as described in the Logical partitioning. For more information about Logical partitioning, see Logical partitioning.
- The Virtual I/O Server logical partition has been created and the Virtual I/O Server has been installed. For instructions, see Installing the Virtual I/O Server and client logical partitions.
- You have created the remaining logical partitions that you want added to the network configuration.
- 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.
While this procedure describes configuration in an HMC environment, this configuration is also possible 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:
- Set up an Ethernet switch with untagged ports. Alternatively, you can use an Ethernet switch that does not use VLAN.
- For system S1, use the HMC to create a virtual Ethernet adapter V11 for the Virtual I/O Server with the Use this adapter for Ethernet bridging trunk setting, with PVID set to 1, and no additional VIDs.
- For system S1, use the HMC to create virtual Ethernet adapters V12 and V13 for logical partitions S11 and S12, respectively, with PVID set to 1 and no additional VIDs.
- For system S1, use the HMC to assign physical Ethernet adapter E11 to the Virtual I/O Server and connect the adapter to the Ethernet switch port P1.
- On the Virtual I/O Server, set up a shared Ethernet adapter (SEA) ent2 with the physical adapter ent0 and virtual adapter ent1 by using the mkvdev -sea ent0 -vadapter ent1 -default ent1 -defaultid 1 command.
- Start the logical partitions. The process recognizes the virtual devices that were created in Step 1.
- Configure IP addresses for S11 (en0), S12 (en0), and S2 (en0), so that they all belong to the same subnet with the router connected to Ethernet switch port P5.
An en2 SEA on the Virtual I/O Server logical partition can also be configured by using the IP addresses on the same subnet. This is required only for network connectivity to the Virtual I/O Server logical partition.
