Syntax of Get-F5.iControl.NetworkingVLAN.Begincreate_v2

I didn't realize it at the time, but there is an article that explains how to use this:

https://devcentral.f5.com/codeshare?sid=183

Here is the code that works if this can help anyone else in the future! I needed to create VLANs that were both tagged and untagged, so I just made 2 functions for each. I'm only listing the tagged VLAN function here, but if you want to make an untagged one then just change the value of member.tag_state to UNTAGGED instead of TAGGED.

function Create-Tagged-VLAN()

{
  param([string]$name,
    [long]$id,
    [string]$member_name);

$vlans = (, $name);
  $vlan_ids = (, $id);
  $member = New-Object -TypeName iControl.NetworkingVLANMemberEntry;
  $member.member_name = $member_name
  $member.member_type = "MEMBER_INTERFACE";
  $member.tag_state = "MEMBER_Tagged"
  $memberA = (, $member);
  $memberAofA = (, $memberA);
  $failsafe_states = (, "STATE_DISABLED");
  $timeouts = (, 1500);
  $mac_masquerade = (, "");

$iControl.NetworkingVLAN.create(
    $vlans,
    $vlan_ids,
    $memberAofA,
    $failsafe_states,
    $timeouts,
    $mac_masquerade);
}

Create-Tagged-VLAN -name "VLAN-500" -id 500 -member_name "1.4";
