One topic that I had been very interested in exploring was the idea of VLAN tagging within ESX Server. ESX Server offers the ability to establish 802.1Q trunks with compatible switches so that 802.1Q tagged frames can be routed to appropriately configured “port groups” within ESX Server. This would allow a single physical host server to run virtual servers in multiple VLANs without requiring a separate physical connection for each VLAN.
The idea of having an ESX Server create an 802.1Q trunk (even using multiple physical connections for redundancy) becomes really important when you move into the larger-scale server consolidation projects. Organizations just won’t have the switch density (or the NIC density on the ESX Server, for that matter) to have multiple physical connections to each VLAN. The ability to “extend” these VLANs into ESX Server’s virtual networking capabilities is very important.

Today, I set out to test this interoperability. A host server running ESX Server 2.5.3 (the latest version, just released a few days ago) was connected to a Cisco Catalyst 3524XL running IOS 12.0(5). The following commands were used to configure the port to which the ESX Server was connected:
Instabro 5 2 6 – browser for instagram url. A quick review of the output from
sh int fa0/18 switchport
(where “fa0/18”, for example, is the interface to which the ESX Server is connected) showed that the port was indeed configured and operating as an 802.1Q trunk.Next, a new VLAN (VLAN ID 10) was created on the switch. No ports were placed into this VLAN because no physical ports were required; the ports would all be coming from ESX Server across the trunk.
Third, port groups were configured in the MUI for ESX Server. Two port groups were configured, one to match the native VLAN on the switch (VLAN 1, typically) and one to match VLAN 10.
Once all of the configuration was done, testing began. Upon moving the first VM to the default port group (this was the port group created to match the native VLAN), I lost connectivity to that VM from other systems connected to other ports also in the native VLAN. Thinking that perhaps all VMs needed to configured for a port group (some VMs were still connected to virtual switches and not port groups), I added the second running VM to the default port group as well. Connectivity was established between the two VMs within the same port group, but I still had no connectivity to other systems on the same VLAN.
After a fair amount of troubleshooting and searching, I came across a reference on the VMware web site regarding the use of native VLANs. VMware recommends against the use of native VLANs because switches tend to strip off the 802.1Q tags for frames on the native VLAN. To make VLAN tagging in ESX Server work in this situation, the switch must be reconfigured to tag all frames, including frames in the native VLAN.

The command in Cisco IOS to do this is
vlan dot1q tag native
. Unfortunately, this command is not supported on the version of IOS that is running on the Catalyst 3524XL I used in the test lab, so there was no way to make VLAN tagging work when using the native VLAN. This is a key “gotcha”—make sure that the switches support tagging native VLAN traffic if you plan to use native VLANs with ESX Server and port groups, otherwise it isn’t going to work.Fotomagico pro 5 6 13 x. As soon as I have the opportunity to upgrade the IOS image on the Catalyst 3524XL switch in the test lab, I’ll try testing port group/VLAN interoperability again and post results here.
UPDATE: I’ve posted some updated information and more comprehensive configuration notes in a posting titled “ESX Server, NIC Teaming, and VLAN Trunking”.

To use Group FaceTime video calls, you need iOS 12.1.4 or later, or iPadOS on one of these devices: iPhone 6s or later, iPad Pro or later, iPad Air 2 or later, iPad mini 4 or later, iPad (5th generation) or later, or iPod touch (7th generation). Earlier models of iPhone, iPad, and iPod touch that support iOS 12.1.4 can join Group FaceTime calls as audio participants.
FaceTime isn't available in all countries or regions.
Start a Group FaceTime call from the FaceTime app
- Go to Settings > FaceTime, and make sure that FaceTime is on.
- Open FaceTime and tap the Add button in the top-right corner.
- Enter the name of your contacts, phone numbers, or emails.
- To start your FaceTime call, tap Audio or Video.
You can add up to 32 people to a Group FaceTime call.
Start a Group FaceTime call from the Messages app
In a group conversation in Messages, you can start Group FaceTime right from the group conversation. Follow these steps:
- Open Messages and start a group conversation. Or go to an existing group conversation.
- Tap the contacts at the top of the group conversation.
- Tap FaceTime , then start your call.
You can add up to 32 people to a Group FaceTime call.
Join a Group FaceTime call
There are a few ways to join a Group FaceTime call that someone else started:
- Tap the notification from the Notification Center or the Lock screen, then tap .
- To join a Group FaceTime call from Messages, tap the notification at the top of your screen or tap Join from the group conversation in Messages. After you tap Join, you're automatically connected.
- To join a call from the FaceTime app, just go to the active call in FaceTime, then tap .

From a group message
Add a person to a Group FaceTime call
- From the call, tap the Add button .
- Tap Add Person.
- Enter the contact's name, phone number, or email.
- Tap Add Person to FaceTime.
When you add someone to your call, you can tap Ring next to their name so their device alerts them of the incoming call.
When someone is added to a Group FaceTime call, they can't be removed from the call. The person who was added to the call needs to end the Group FaceTime call.
Add camera effects to your Group FaceTime calls
If you have an iPhone X or later, or an iPad Pro 11-inch (1st and 2nd generation) or iPad Pro 12.9-inch (3rd generation and later), you can use Animoji and Memoji in your Group FaceTime calls. On devices without Face ID, you can use other camera effects, like filters, text, and shapes in your Group FaceTime calls.
To use an Animoji or Memoji:
- During a FaceTime call, tap .
- Tap , then pick your Animoji or Memoji.
To use other camera effects:
- During a FaceTime call, tap the Effects button .
- Tap Filters , Text , or Shapes , Memoji stickers, *, and Emoji stickers *.
You need an iPhone X or later, or an iPad Pro 11-inch (1st and 2nd generation) or iPad Pro 12.9-inch (3rd generation and later) to use Animoji and Memoji. Not all filters and effects are supported on all devices. You need iOS 13 or iPadOS to use Memoji stickers and Emoji stickers.
Change FaceTime audio and video settings
You can change the audio and video settings in the FaceTime app at any time during a call. To change your settings, tap the screen, then swipe up to see more options or tap one of these options:
Tap Camera off to turn the camera off. Tap it again to turn it back on*.
Tap Flip to switch to the rear camera. Tap it again to switch back to the front-facing camera.
Tap Mute to turn off the sound. Tap Mute again to turn the sound back on.
Tap Speaker to switch between mute and the speaker.
If you don't see the Camera button , check to see if your device is compatible.
The tile of the person speaking gets larger automatically during a Group FaceTime call. To disable this, go to Settings > FaceTime. Under Automatic Prominence, turn off Speaking.
* To use Group FaceTime video calls, you need iOS 12.1.4 or later, or iPadOS on one of these devices: iPhone 6s or later, iPad Pro or later, iPad Air 2 or later, iPad mini 4 or later, iPad (5th generation) or later, or iPod touch (7th generation).
