Networking Samples

Define Ethernet and Fibre Channel networks, create network sets, and build Logical Interconnect Groups with uplink sets using POSH-HPEOneView sample scripts.

Three sample scripts cover network resource creation:

Script	Purpose
DefineNetworks_Sample.ps1	Single Virtual Connect — Ethernet networks, bulk VLAN creation, network sets, FC networks
DefineNetworks_AA_VC_Sample.ps1	Active/Active Virtual Connect — VLAN networks with paired A/B naming for MLAG
DefineLogicalInterconnectGroup_Sample.ps1	LIG creation with Ethernet and FC uplink sets

Connecting to the appliance

All three scripts check for an existing session before prompting:

if (-not $ConnectedSessions)
{
    $Appliance  = Read-Host 'ApplianceName'
    $Credential = Get-Credential -UserName Administrator -Message Password
    $ApplianceConnection = Connect-OVMgmt -Hostname $Appliance -Credential $Credential
}

---

DefineNetworks_Sample.ps1

This script creates a representative set of Ethernet and FC networks for a standard single-VC deployment.

Get-OVNetwork
Get-OVNetworkSet

Create individual Ethernet networks

# Named networks for clarity
$status = 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

Bulk network creation from a VLAN range

The -vlanRange parameter accepts comma-separated ranges, creating one network per VLAN ID automatically:

# Creates 23 networks: NetSuffix_100 through NetSuffix_120, NetSuffix_123, NetSuffix_135
New-OVNetwork -Name "NetSuffix" -vlanRange "100-120,123,135"

Create a Network Set

Network sets group multiple Ethernet networks behind a single logical port in a server profile. The UntaggedNetwork carries untagged frames for that port.

$network20 = Get-OVNetwork -name "blue"   -type "Ethernet"
$network30 = Get-OVNetwork -name "green"  -type "Ethernet"
$network40 = Get-OVNetwork -name "yellow" -type "Ethernet"

New-OVNetworkSet -name "Production Networks" `
    -UntaggedNetwork $network20 `
    -Networks $network20,$network30,$network40

Create Fibre Channel networks

# Fabric-attached FC networks (auto login redistribution enabled)
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 external fabric)
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"

Get-OVNetwork

DefineNetworks_AA_VC_Sample.ps1 — Active/Active configuration

In an Active/Active (MLAG) deployment both Virtual Connect modules carry all VLANs. Networks are typically named with a VLAN <id> convention rather than A/B suffixes, because both modules share the same uplink set.

Create VLAN networks

# Initial network
$status = New-OVNetwork -Type "Ethernet" -Name "VLAN 10" -VlanId 10 -Smartlink $true
Get-OVNetwork -Name "VLAN 10" -Type Ethernet

# Bulk creation for VLANs 20-60
20,30,40,50,60 | ForEach-Object {
    New-OVNetwork -Type "Ethernet" -Name "VLAN $_" -VlanId $_ -Smartlink $true
}

Network Set for A/A

$network20 = Get-OVNetwork -Name "VLAN 20" -Type "Ethernet"
$network30 = Get-OVNetwork -Name "VLAN 30" -Type "Ethernet"
$network40 = Get-OVNetwork -Name "VLAN 40" -Type "Ethernet"

New-OVNetworkSet -Name "Production Networks" `
    -UntaggedNetwork $network20 `
    -Networks $network20, $network30, $network40

Get-OVNetworkSet -Name "Production Networks"

FC networks (same as single-VC)

New-OVNetwork -Name "Production Fabric A" -Type FC `
    -typicalBandwidth 4000 -autoLoginRedistribution $true
New-OVNetwork -Name "Production Fabric B" -Type FC `
    -typicalBandwidth 4000 -autoLoginRedistribution $true
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"

Get-OVNetwork

The key difference between DefineNetworks_Sample.ps1 and DefineNetworks_AA_VC_Sample.ps1 is naming convention and how uplink sets are later configured in the LIG. In A/A mode, a single uplink set spans both VC bays rather than separate A and B uplink sets.

---

DefineLogicalInterconnectGroup_Sample.ps1

A Logical Interconnect Group (LIG) defines the interconnect module layout and uplink connectivity for an enclosure. This script creates a LIG with FlexFabric modules in bays 1 and 2, then adds Ethernet and FC uplink sets.

Prerequisites check

$networks = Get-OVNetwork -type Ethernet

if ($networks -eq $null)
{
    Write-Host "There are no defined Ethernet Networks. Please create some."
    break
}

Create the LIG with SNMP configuration

The SNMP hashtable defines read community, trap destinations, trap severities, and access lists inline:

$LIGName = "LIG Prod"
$Bays    = @{1 = "FlexFabric"; 2 = "FlexFabric"}

$SNMP = @{
    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 $snmp |
    Wait-OVTaskComplete |
    Get-OVLogicalInterconnectGroup

Add an Ethernet uplink set

Uplink sets bind networks to physical uplink ports on the interconnect modules. The BAY1:X4 notation means bay 1, port X4.

$Networks = "red","blue","green" | Get-OVNetwork -Type Ethernet

$newUT = $NewLig | New-OVUplinkSet `
    -Name LUT1 `
    -Type "Ethernet" `
    -Networks $Networks `
    -NativeEthNetwork $Networks[0] `
    -UplinkPorts "BAY1:X4","BAY1:X5","BAY2:X4","BAY2:X5" `
    -EthMode "Auto"

Add Fibre Channel uplink sets

Each FC fabric gets its own uplink set. Refresh the LIG object between additions to pick up the previous uplink set’s changes.

$FabricA = Get-OVNetwork -Name "Production Fabric A" -Type FibreChannel
$FabricB = Get-OVNetwork -Name "Production Fabric B" -Type FibreChannel

# Fabric A — ports X1 and X2 on bay 1
$NewLig = Get-OVLogicalInterconnectGroup -Name $LIGName
$newUT  = $NewLig | New-OVUplinkSet -Name "Fabric A" `
    -Type "FibreChannel" -Networks $FabricA -UplinkPorts "BAY1:X1,BAY1:X2"

# Fabric B — ports X1 and X2 on bay 2
$NewLig = Get-OVLogicalInterconnectGroup -Name $LIGName
$newUT  = $NewLig | New-OVUplinkSet -Name "Fabric B" `
    -Type "FibreChannel" -Networks $FabricB -UplinkPorts "BAY2:X1,BAY2:X2"

Wrap the LIG in an Enclosure Group

From CreateEnclosureGroup_Sample.ps1, once the LIG is ready:

$enclGroup = New-OVEnclosureGroup `
    -Name "Prod VC FlexFabric Group 1" `
    -LogicalInterconnectGroup $NewLig

Uplink port notation

Format	Meaning
BAY1:X4	Bay 1, Ethernet uplink port X4
BAY2:X1,BAY2:X2	Bay 2, FC ports X1 and X2
Enclosure1:Bay3:Q1	Synergy frame 1, bay 3, QSFP port 1

Always re-fetch the LIG object (Get-OVLogicalInterconnectGroup) after each New-OVUplinkSet call. The cmdlet returns the task, not the updated LIG, so the in-memory object becomes stale.
