VLAN Tagging in 12.2

Among the new features in Ops Center 12.2 is support for VLAN tagging. VLAN tagging lets you use VLANs that span more than one network switch, giving you more flexibility in your network setup.

When you attach a network to an Oracle VM server or global zone, you can attach the network in tagged mode or untagged mode. In tagged mode, the VLAN ID is added to the ethernet frame by the network device such as the switch. In untagged mode, VLAN ID is not added to the ethernet frame.

It's a good idea, when you're creating a server pool, to combine assets that are associated with networks in the same mode. If you have a server pool with some assets on a tagged network and others on an untagged network, then a logical domain OS will lose its network configuration if it's moved from one sort of asset to another.

For more information about VLAN tagging, take a look at the Oracle VM Server for SPARC chapter in the Feature Reference Guide.
