Defining a network
To define a standalone network:
1.
Enter a network name. The network name can be up to 64 characters in length (no spaces).
2.
To add a color to the network, select a color from the Color pull-down menu. The network color is used
as a visual identifier for the network within VCM.
3.
To add labels to the network, type a label in the Labels field, and then press Enter. Labels are used as
text-based identifiers for the network within VCM. Each label can contain up to 24 characters,
excluding spaces. Each network can have up to 16 labels.
4.
Select whether to enable (checked) or disable (unchecked) Smart Link (on page
The checkbox is not available until an uplink is added to the network.
5.
Select whether to designate (checked) or not designate (unchecked) this network as a private network
" on page
6.
Select whether to enable (checked) or disable (unchecked) VLAN tunneling ("
7.
If the network is to be used only internal to the Virtual Connect domain or enclosure, go to step 9 (do not
add any external ports).
8.
Use the cascading menu to select a port, and then click Add to add one or more external ports. To
ensure a high availability connection, select two or more ports.
Only available ports are listed, displaying the current port link status.
9.
Select the speed and duplex (where applicable) of the uplink ports. Click the pull-down box under
Speed/Duplex, and then select a setting. Half-duplex operation is not supported by the VC-Enet
module.
IMPORTANT:
Be sure that the uplink interface port speed matches the speed set on the
corresponding network switch port. If using autonegotiation, both ports must be configured to use
autonegotiation or they might not link.
10.
Select the Connection Mode:
o
Auto (recommended)—This mode enables the uplinks to attempt to form aggregation groups using
IEEE 802.3ad link aggregation control protocol, and to select the highest performing uplink as the
active path to external networks.
Aggregation groups require multiple ports from a single VC-Enet module to be connected to a single
external switch that supports automatic formation of LACP aggregation groups, or multiple external
switches that utilize distributed link aggregation. HP has guidelines available for users who prefer
to connect to external switches that support distributed link aggregation capabilities.
Multiple aggregation groups may be formed from the ports selected for the network. The highest
performing aggregation group is selected as active, with other aggregation groups and individual
links used as standby connections.
o
Failover—If this mode is selected, set the port to Primary or Secondary. Only a single link is used as
the active link to the external networks, with other ports used as standby connections.
11.
In the Network Access Groups field, begin typing the name of a Network Access Group that should
include this network. When the Network Access Group name appears, select the name.
To use a network access group, it must already be defined. For more information, see "Define Network
Access Group screen (on page
)."
12.
Click Apply. The network is now defined and available for use in creating server profiles.
