Q: How do I add a new port group to a virtual switch on each ESX host
A: Using powercli you could run the following:
[sourcecode language="powershell"]
$cluster_name = "Your_Cluster_Name"
$vSwitch = "vSwitch_you_want_to_add_vlan_to"
$PortGroupName = "Name_of_Your_Port_Group"
$PortGroupVLAN = "VLAN_of_Your_Port_Group"
foreach ($esx in get-VMhost -Location $cluster_name | sort Name) { $esx | Get-VirtualSwitch -Name $vSwitch | New-VirtualPortGroup -Name “$PortGroupName″ -VlanId $PortGroupVLAN }
[/sourcecode]
Q: How do I change the number of ports on my vSwitch using PowerCli
A: With the following commands:
[sourcecode language="powershell"]
$vSwitch = "Your_vSwitch_Name"
$NumberPorts = "Number_of_ports"
Get-VMHost | % {Get-VirtualSwitch -VMHost $_ -Name $vSwitch | % { Set-VirtualSwitch -VirtualSwitch $_ -NumPorts "$NumberPorts" }
[/sourcecode]
Q: How do I create a vSwitch from PowerCli
A: With this code:
[sourcecode language="powershell"] # You can do multiple vmnic's on the command just use a , between $vmnic = "Name_of_vmnic_you_want_assigned_to_switch" $vSwitch = "Name_of_new_vSwitch" $NumPorts = "Number_of_ports" New-VirtualSwitch -Name $vSwitch -NumPorts $NumPorts -Nic $vmnic [/sourcecode]
