Configure default settings on a VMware virtual distributed switch

Original blog post and full text is here. All credits go to http://kickingwaterbottles.wordpress.com

Here is the PowerCLI script that will set the ‘Teaming and Failover’ defaults on the vDS to work with etherchannel and two active uplinks.

connect-viserver vCenter
$vDSName = “”
$vds = Get-VDSwitch $vDSName
$spec = New-Object VMware.Vim.DVSConfigSpec
$spec.configVersion = $vds.ExtensionData.Config.ConfigVersion
$spec.defaultPortConfig = New-Object VMware.Vim.VMwareDVSPortSetting
$uplinkTeamingPolicy = New-Object VMware.Vim.VmwareUplinkPortTeamingPolicy
# Set load balancing policy to IP hash
$uplinkTeamingPolicy.policy = New-Object VMware.Vim.StringPolicy
$uplinkTeamingPolicy.policy.inherited = $false
$uplinkTeamingPolicy.policy.value = “loadbalance_ip”
# Configure uplinks. If an uplink is not specified, it is placed into the ‘Unused Uplinks’ section.
$uplinkTeamingPolicy.uplinkPortOrder = New-Object VMware.Vim.VMwareUplinkPortOrderPolicy
$uplinkTeamingPolicy.uplinkPortOrder.inherited = $false
$uplinkTeamingPolicy.uplinkPortOrder.activeUplinkPort = New-Object System.String[] (2) # (#) designates the number of uplinks you will be specifying.
$uplinkTeamingPolicy.uplinkPortOrder.activeUplinkPort[0] = “dvUplink1″
$uplinkTeamingPolicy.uplinkPortOrder.activeUplinkPort[1] = “dvUplink2″
# Set notify switches to true
$uplinkTeamingPolicy.notifySwitches = New-Object VMware.Vim.BoolPolicy
$uplinkTeamingPolicy.notifySwitches.inherited = $false
$uplinkTeamingPolicy.notifySwitches.value = $true
# Set to failback to true
$uplinkTeamingPolicy.rollingOrder = New-Object VMware.Vim.BoolPolicy
$uplinkTeamingPolicy.rollingOrder.inherited = $false
$uplinkTeamingPolicy.rollingOrder.value = $true
# Set network failover detection to “link status only”
$uplinkTeamingPolicy.failureCriteria = New-Object VMware.Vim.DVSFailureCriteria
$uplinkTeamingPolicy.failureCriteria.inherited = $false
$uplinkTeamingPolicy.failureCriteria.checkBeacon = New-Object VMware.Vim.BoolPolicy
$uplinkTeamingPolicy.failureCriteria.checkBeacon.inherited = $false
$uplinkTeamingPolicy.failureCriteria.checkBeacon.value = $false
$spec.DefaultPortConfig.UplinkTeamingPolicy = $uplinkTeamingPolicy
$vds.ExtensionData.ReconfigureDvs_Task($spec)

and here is simplified version

$vDSName = “XXX”  ## << dvSwitch name

$vds = Get-VDSwitch $vDSName

$spec = New-Object VMware.Vim.DVSConfigSpec

$spec.configVersion = $vds.ExtensionData.Config.ConfigVersion

$spec.defaultPortConfig = New-Object VMware.Vim.VMwareDVSPortSetting

$uplinkTeamingPolicy =  New-Object VMware.Vim.VmwareUplinkPortTeamingPolicy

# Set load balancing policy to IP hash

$uplinkTeamingPolicy.policy = New-Object VMware.Vim.StringPolicy

$uplinkTeamingPolicy.policy.inherited = $false

$uplinkTeamingPolicy.policy.value = “loadbalance_ip”   ## << Teaming Policy Type

$spec.DefaultPortConfig.UplinkTeamingPolicy = $uplinkTeamingPolicy

$vds.ExtensionData.ReconfigureDvs_Task($spec)
