HPE OneView models the network fabric as a hierarchy: individual networks are grouped into network sets, logical interconnects are defined by logical interconnect groups (LIGs), and uplinks are defined in uplink sets within a LIG.

​
Creating Ethernet networks

New-OVNetwork creates a single tagged Ethernet network. Use -vlanId for a specific VLAN, or -vlanRange to bulk-create a set of networks in one call. 
New-OVNetwork -Type Ethernet -Name "Production VLAN 100" -vlanId 100 -smartlink $true -Purpose General
The DefineNetworks_Sample.ps1 sample creates several named networks for illustration: 
# From DefineNetworks_Sample.ps1
New-OVNetwork -Type Ethernet -Name "red"    -vlanId 10 -smartlink $true
New-OVNetwork -Type Ethernet -Name "blue"   -vlanId 20 -smartlink $true
New-OVNetwork -Type Ethernet -Name "green"  -vlanId 30 -smartlink $true
New-OVNetwork -Type Ethernet -Name "yellow" -vlanId 40 -smartlink $true
New-OVNetwork -Type Ethernet -Name "black"  -vlanId 50 -smartlink $true

​
Creating Fibre Channel networks

FC networks use -type FibreChannel. Set -fabricType to FabricAttach (default, connects through a SAN fabric) or DirectAttach (flat SAN, directly attached to the server). 
# Fabric-attached FC networks (connects through a Brocade or Cisco SAN)
New-OVNetwork -Name "Production Fabric A" -Type FC -typicalBandwidth 4000 -autoLoginRedistribution $true
New-OVNetwork -Name "Production Fabric B" -Type FC -typicalBandwidth 4000 -autoLoginRedistribution $true

# Direct-attach FC (no SAN switch)
New-OVNetwork -Name "DirectAttach Fabric A" -Type FC -typicalBandwidth 4000 -autoLoginRedistribution $true -fabrictype DirectAttach
New-OVNetwork -Name "DirectAttach Fabric B" -Type FC -typicalBandwidth 4000 -autoLoginRedistribution $true -fabrictype DirectAttach
For fabric-attached networks, add a SAN manager first (Add-OVSanManager) and then use -managedSan to associate the network with a managed SAN zone.

​
Creating network sets

A network set groups multiple Ethernet networks so a server profile connection can carry multiple VLANs on a single NIC. The -UntaggedNetwork specifies which network sends and receives untagged frames. 
# Retrieve network objects
$network20 = Get-OVNetwork -Name "blue"   -Type Ethernet
$network30 = Get-OVNetwork -Name "green"  -Type Ethernet
$network40 = Get-OVNetwork -Name "yellow" -Type Ethernet

# Create the network set
New-OVNetworkSet -Name "Production Networks" `
    -Networks $network20, $network30, $network40 `
    -UntaggedNetwork $network20

​
Network set with bandwidth limits

$ProdNetsA = Get-OVNetwork -Name "VLAN *0-A" -ErrorAction Stop

New-OVNetworkSet -Name "Prod NetSet1 A" `
    -Networks $ProdNetsA `
    -UntaggedNetwork $ProdNetsA[0] `
    -TypicalBandwidth 2500 `
    -MaximumBandwidth 10000

​
Creating logical interconnect groups

A logical interconnect group (LIG) defines the desired configuration of the interconnect modules inside an enclosure. You specify which module goes in which bay, SNMP settings, and whether IGMP snooping is enabled. 
$LigName     = "LIG Prod"
$Bays        = @{ 1 = "FlexFabric"; 2 = "FlexFabric" }
$SnmpConfig  = @{
    readCommunity  = "MyTr@p1"
    enabled        = $true
    systemContact  = "Network Admin"
    snmpAccess     = @("192.168.1.2/32", "10.1.1.0/24")
    trapDestinations = @(
        @{
            trapDestination = "myhost.local"
            communityString = "MyTr@p2"
            trapFormat      = "SNMPv1"
            trapSeverities  = @("Critical","Major","Minor","Warning","Normal","Info","Unknown")
            fcTrapCategories = @("PortStatus", "Other")
        }
    )
}

$NewLig = New-OVLogicalInterconnectGroup -Name $LigName -Bays $Bays -Snmp $SnmpConfig |
    Wait-OVTaskComplete |
    Get-OVLogicalInterconnectGroup

​
Advanced LIG with IGMP snooping and internal networks

$InternalNetworks = "Live Migration", "Heartbeat" | ForEach-Object { Get-OVNetwork -Name $_ -ErrorAction Stop }

$CreatedLig = New-OVLogicalInterconnectGroup `
    -Name "Default VC FF LIG" `
    -Bays @{ 1 = 'Flex2040f8'; 2 = 'Flex2040f8' } `
    -EnableIgmpSnooping $true `
    -InternalNetworks $InternalNetworks |
    Wait-OVTaskComplete |
    Get-OVLogicalInterconnectGroup
Uplink sets are defined within a LIG and specify which physical ports carry which networks to the upstream switch. 
$Networks = "red", "blue", "green" | Get-OVNetwork -Type Ethernet
$FabricA  = Get-OVNetwork -Name "Production Fabric A" -Type FibreChannel
$FabricB  = Get-OVNetwork -Name "Production Fabric B" -Type FibreChannel

# Ethernet uplink set across bays 1 and 2
$NewLig | New-OVUplinkSet `
    -Name "LUT1" `
    -Type Ethernet `
    -Networks $Networks `
    -NativeEthNetwork $Networks[0] `
    -UplinkPorts "BAY1:X4", "BAY1:X5", "BAY2:X4", "BAY2:X5" `
    -EthMode Auto

# Re-fetch the LIG after each modification
$NewLig = Get-OVLogicalInterconnectGroup -Name $LigName

# FC uplink sets
$NewLig | New-OVUplinkSet -Name "Fabric A" -Type FibreChannel -Networks $FabricA -UplinkPorts "BAY1:X1", "BAY1:X2"
$NewLig = Get-OVLogicalInterconnectGroup -Name $LigName
$NewLig | New-OVUplinkSet -Name "Fabric B" -Type FibreChannel -Networks $FabricB -UplinkPorts "BAY2:X1", "BAY2:X2"
You must re-fetch the LIG object after each New-OVUplinkSet call because the task updates the object on the appliance. Using a stale in-memory object will cause the next uplink set to overwrite the previous one.

​
Creating an enclosure group from a LIG

After the LIG is complete, create an enclosure group that references it: 
$EnclosureGroup = New-OVEnclosureGroup `
    -Name "Prod VC FlexFabric Group 1" `
    -LogicalInterconnectGroup $NewLig

​
Updating logical interconnects

After changing a LIG, push the changes to the deployed logical interconnects: 
# Get all logical interconnects that are inconsistent with their group
Get-OVLogicalInterconnect | Where-Object complianceState -NE Consistent | Update-OVLogicalInterconnect
Updating a logical interconnect may briefly disrupt network traffic while interconnect modules are reconfigured. Schedule updates during a maintenance window.

Listing existing networks and network sets

Get-OVNetwork -Type Ethernet

# All FC networks
Get-OVNetwork -Type FibreChannel

# All networks (Ethernet and FC)
