HP Matrix Operating Environment 7.3 Update 1 Installation and Configuration Guide for Provisioning with Virtual Resources

3. Define the VLANs that can be carried by one physical network.
a. In the infrastructure orchestration console Networks tab, click Create Network.
b. Specify a VLAN ID, and set Network Address, Network Mask, Default Gateway, MS
Domain, and WINS Servers for that VLAN ID by clicking the appropriate tab and filling
in the information.
In a multi-home scenario where there are multiple default gateway options, IO determines
the default gateway from the network connected to the NIC that is declared as primary.
Each Physical network that carries one or more VLANs is a “Trunk, Physical” network.
Newly defined VLANs appear in Networks table, with “VLAN” displayed in the Type Column.
One, and only one, trunk per VLAN implies that a trunk carries either all possible VLANs to
every cluster, or networks (such as a deployment network) cannot be shared between trunks
in different clusters.
Configuring trunk and VLAN networks to enable support for Hyper-V VLAN tagging
VLAN tagging is the practice of inserting a VLAN ID into network data to identify the VLAN to
which the data belongs.
CAUTION: Combining tagged and untagged Hyper-V virtual machines on the same virtual
network results in network failures. HP recommends that you maintain a homogeneous network
environment among cooperating Hyper-V VM Hosts. To achieve this, for all uses of a named virtual
switch, use a tagged network on all hosts or use an untagged network on all hosts.
If your environment is configured to use HP NCU to create vNICs for each VLAN on Hyper-V VM
Hosts (the supported method for VLAN tagging in previous releases), and you upgrade infrastructure
orchestration to 7.0, network failures may occur on the Hyper-V VM guests if you attempt to use
the new method of VLAN tagging described in the following procedure.
The property promiscous.switch.compatibility is included in hpio.properties,
located in the default location at ..\Program Files\HP\Matrix infrastructure
orchestration\conf. This property allows administrators who have configured their environment
for VLAN tagging using HP NCU to continue to use this method without reconfiguring their Hyper-V
systems.
