Change Network Failover Detection Policy on vSwitches and portgroups.

Need to change the NetworkFailoverDetectionPolicy for all your vSwithes and portgroups?  The following script traverses all clusters and host to check the NetworkFailoverDetectionPolicy for Beacon Probing.  If its Beacon Probing, change it to Link Status.

#import-module VMware.VimAutomation.Core

#Connect-VIServer -Server vcenter_hostname

#uncomment for testing

#$vmhosts = "hostname1","hostname2"

　

#uncomment for live run

#get the hostnames of all the hosts in every cluster

$vmhosts = get-cluster | get-vmhost | select name

foreach($vmhost in $vmhosts)

{

    #Gets all the vSwitch names that has beacon probing set on the host.

    $switch_policy = Get-VirtualSwitch -VMHost $vmhost.Name | where {$_.Name -ne "vSwitchiDRACvusb"} | Get-NicTeamingPolicy | Where-Object {$_.NetworkFailoverDetectionPolicy -eq "BeaconProbing"} | select -ExpandProperty VirtualSwitch # | select VirtualSwitch | format-wide

    if ($switch_policy)

    {

        foreach ($switch in $switch_policy)

        {

            $vs = Get-VirtualSwitch -VMHost $vmhost.Name -Name $switch

            Get-NicTeamingPolicy -VirtualSwitch $vs | Set-NicTeamingPolicy -NetworkFailoverDetectionPolicy LinkStatus

        }

    }

　

    #Gets all the port group names that has beacon probing set on the host.

    $portgroup_policy = Get-VirtualPortGroup -VMHost $vmhost | Get-NicTeamingPolicy | Where-Object {$_.NetworkFailoverDetectionPolicy -eq "BeaconProbing"} | select -ExpandProperty VirtualPortGroup

    if ($portgroup_policy)

    {

        foreach ($p in $portgroup_policy)

        {

            #Sets the nicteamingpolicy from the host and its portgroup.

            $vpg = Get-VirtualPortGroup -VMHost $vmhost.Name -Name $p

            Get-NicTeamingPolicy -VirtualPortGroup $vpg | Set-NicTeamingPolicy -NetworkFailoverDetectionPolicy LinkStatus

        }

    }
