You can dynamically change the VLAN IDs of a virtual Ethernet
adapter for a running logical partition by using the Hardware Management Console (HMC).
Before you begin
Before you start, verify that the Virtual I/O Server is at version
2.2.0.0, or later.
About this task
For more information about managing virtual network connections on a
logical partition when the HMC is at version 8.7.0, or
later, see Managing virtual network connections.
What to do next
After changing the VLAN IDs of a virtual Ethernet adapter,
access any existing partition profiles for the logical partition and
add the VLAN IDs of the virtual Ethernet adapters to the partition
profiles. The dynamically set values in the additional VLANs are lost
if you have shut down and then activated the logical partition by
using a partition profile that does not have the new list of VLAN
IDs of the virtual Ethernet adapter.
