Set-VDSwitch NumUplinkPorts Bug

During my PowerCLI scripting for the provisioning of new ESX Hosts i have found another bug. The Set-VDSwitch CMDlet does not set the number of uplink ports correctly in every case.

You can change the number of uplink ports from 2 to 4 without problems, but the configuration back to two uplinks silently fails.

Set-VDSwitch -VDSwitch $dvSwitchObject -NumUplinkPorts “4″ -Confirm:$false

The dvSwitch has 4 uplink ports after the configuration change.

Set-VDSwitch -VDSwitch $dvSwitchObject -NumUplinkPorts “2″ -Confirm:$false

The dvSwitch still has 4 uplink ports after this configuration change. The CMDlet finishes without an error, but the configuration is unchanged. Currently i have no automation workaround for that, but i can change the settings in the vSphere Web Client manually.

I have opened a VMware SR. Let’s see if this bug is fixed in the next PowerCLI version.
