Note: The IVM creates
four default virtual Ethernet adapters on the port virtual LANs 1,
2, 3, and 4. Therefore, you cannot use the IEEE 802.1Q virtual LAN
tags on the virtual LANs 1, 2, 3, or 4 with the IVM.
You
can configure the following types of Ethernet on your managed system:
- You can create virtual Ethernet bridges on your managed system.
Virtual Ethernet bridges, also known as Shared Ethernet Adapters, connect
the virtual Ethernet networks on your managed system to physical Local
Area Networks (LANs). For greater security, do not set up the physical
Ethernet adapter that you use to connect to the management partition
as a virtual Ethernet bridge. This permits you to isolate the management
partition from all external networks. (The management partition manages
the virtual Ethernet networks on your managed system but does not
participate in any virtual Ethernet networks.)
Note: This is the
only method that you can use to configure Ethernet for an IBM® i partition.
If
you configure a single physical Ethernet adapter or link aggregation
to connect to the management partition and to act as a virtual Ethernet
bridge, consider using OpenSSL and Portable OpenSSH on the management
partition. You can use OpenSSL and Portable OpenSSH to connect securely
to the Virtual I/O Server from
a remote location.
You do not need to select a physical Ethernet
adapter or link aggregation for a virtual Ethernet network. If no
physical adapter or link aggregation is set for a virtual Ethernet
network, then the logical partitions on the virtual Ethernet network
can communicate with one another, but they cannot communicate directly
with a physical network.
- You can configure a Host Ethernet Adapter port. A Host Ethernet Adapter is a unique
Ethernet adapter that is built into the system. It provides the ability
to partition a physical Ethernet port. A Host Ethernet Adapter can contain
one or more physical ports and each physical port can be assigned
to zero or more logical partitions.
Note: You cannot configure an IBM i partition to use a Host Ethernet Adapter.
- You can assign a physical Ethernet adapter to
a client logical partition.
Note: You cannot assign a physical
adapter to an IBM i partition.
