HP OneView - Manual (Page 139)

When defined on this appliance, Ethernet networks connected to enclosure interconnects require
a VLAN ID.
•
You can add multiple Ethernet networks that use the same VLAN ID. This capability is required
for logical interconnects that use an
active/active configuration .
•
Each network name in the appliance must be unique.
•
The number of networks supported on an appliance is limited by the number of networks
added, not the number of VLAN IDs that are used.
18.4.2 Managing Ethernet networks
When you add an Ethernet network to the appliance, you are adding a VLAN to the configuration.
VLANs allow multiple networks to use the same physical connections. Servers can specify networks
without knowledge of the underlying hardware configuration.
When you add an Ethernet network, you might also want to an existing network set or add it to a
new network set. For example, by adding the Ethernet network to an existing network set, all servers
that have connections to the network set can access the added network without requiring you to
change the server profiles.
For Ethernet connections, a logical uplink is a way to identify interconnect module uplinks that
carry multiple networks over the same cable. When you add a network, you must also add it to
an existing uplink set or a new uplink set.
You can manage networks and network sets from the UI Networks and Network Sets screens or
by using the REST APIs.
IMPORTANT: HP recommends that you back up the appliance after you make configuration
changes to networks. For information about backing up the appliance, see “Backing up an
appliance” (page 171) .
18.4.2.1 Roles
•
Minimum required privileges: Infrastructure administrator or Network administrator
18.4.2.2 Tasks for Ethernet networks
The appliance online help provides information about using the UI or the REST APIs to:
•
Add, edit (change a network configuration), and delete a network.
•
Add, edit, and delete a network set.
18.5 Data center switch port requirements
Although you can configure an uplink set to receive incoming network traffic as untagged by
designating a network in that uplink set as Native, traffic egressing the uplink set is always VLAN
tagged.
The switch ports for data center network switches that connect to the Virtual Connect interconnect
modules must be configured as follows:
•
Spanning tree edge (because the Virtual Connect interconnect modules appear to the switch
as access devices instead of switches).
•
VLAN trunk ports (tagging) to support the VLAN IDs included in the uplink set that connects
to switch port.
For example, if you configure an uplink set, prodUS, that includes the production networks
prod 1101
through prod 1104 to use the X2 ports of the interconnects in bay 1 and bay
