HP Matrix Operating Environment 7.3 and 7.3 Update 1 Infrastructure Orchestration User Guide

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 homogenous 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 or later, 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 created vNICs to continue to use this method without reconfiguring
their Hyper-V systems.

Configuring networks for Hyper-V VLAN tagging: 7.0 and later method
Perform the following steps in the infrastructure orchestration console to enable support for VLAN
tagging. This is the 7.0 or later method.
1. Discover virtual networks by refreshing the infrastructure orchestration console Networks tab.
2. On the Networks tab, select the 802.1Q network carrying multiple VLAN IDs and click Edit
Network.
3. Select the Trunk tab.
4. Click to select the Trunk check box, and then click Save.
5. Define the VLANs that can be carried by the Hyper-V virtual trunk network.
a. On the Networks tab, click Create Network, or Edit Network to edit an existing 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.
c. Click Save.
Migrating networks for Hyper-V VLAN tagging: 6.3 method to the 7.0 and later method
Perform the one of the following procedures to migrate VLAN tagged Hyper-V VM Hosts configured
using the 6.3 method to the new 7.0 or later method.
