The following tasks can be completed by using the Add Virtual Network wizard:
Create internal or bridged networks
Create tagged or untagged virtual networks
Create a virtual network on an existing or a new virtual switch
Create a load group or select an existing load group
Network Bridge Management
From a server that is managed by the HMC, it is possible to change the PowerVM virtual
network bridge properties, the changes allowed are:
Enable or disable network failover in the Failover field.
Enable or disable load balancing in the Load Balance field.
Change the primary Virtual I/O Server (VIOS) and the physical adapter location from the
table.
Enable Jumbo Frame on the network bridge for the virtual Ethernet adapter to
communicate to an external network.
Enable QoS on the network bridge to check the priority value of all tagged packets and
arrange those packets in the corresponding queue.
Link Aggregation Management
A link aggregation device can be added on the VIOS by using the Add Link Aggregation
device wizard. The same wizard can be used to change a Link Aggregation device's
properties or remove a Link Aggregation device.
PowerVM networking concepts review
PowerVM includes extensive and powerful networking tools and technologies, which can be
used to enable more flexibility, better security, and enhanced usage of hardware resources.
Some of these terms and concepts are unique to the Power Architecture. Table 3-5
introduces the PowerVM virtual networking technologies.

Definition
Enables interpartition communication without assigning a physical
network adapter to each partition. If the virtual network is bridged,
partitions can communicate with external networks. A virtual
network is identified by its name or VLAN ID and the associated
virtual switch.
Enables a client logical partition to send and receive network traffic
without a physical Ethernet adapter.
An in-memory, hypervisor implementation of a layer-2 switch.
A software adapter that bridges physical and virtual networks to
enable communication. A network bridge can be configured for
failover or load sharing.
A link aggregation (also known as Etherchannel) device is a
network port-aggregation technology that allows several Ethernet
adapters to be aggregated.
