Multiple NICs on Multiple vLANs

[TheCableGuy96]

Hi,

I'm new to ESXi and have managed to get hold of an old Dell R720xd and put ESXi 8 on it.

It has 4 NICs and I'm really struggling to see how I can assign each one a different IP on different vLANs so I can assign different nodes t different vLANs.

Would anyone be able to offer me any help please?

Thank you in advance!

Okay that's done... I'm just having an issue with the vLANs.

I've created my vLANs, 1, 5, 10,etc...

I've booted from a vmdk and it wasn't responding. So I looked at the switch and set the ports for the NICs to "T" on vLAN1 and the VM came online, but then I lost access to the VMWare Web Interface.

I thought then maybe I don't need a to create a port group for vLAN1, but there's no option when creating the vLAN1 to select anything other than the created groups.

So how do I get some VMs on the default vLAN1?

A VLAN ID on a virtual port group must only be set for VLANs other than the physical switch's native/default VLAN.

Sorry I'm not totally understanding...

The management interface is set to vLAN0 by default but it's residing on vLAN1.

If I want to assign a VM to vLAN1 there's no option for the management vLAN when creating a VM, just all the other vLAN groups I created.

So to assign a VM to vLAN1 I have to create another group and assign it that that vLAN1.

Once it boots into it I can't access it unless I trunk the ports but then in doing so it stops access to the web interface on the management interface.

The only way around it I can think of is to change the management vLAN from 0 to 1 and trunk the ports then I think I should be able to access both the management web interface and the VM itself?

hat you may do is to simply create a new Virtual Machine Portgroup with the desired name (can be "VLAN1") but let the VLAN-ID for that port group at its default "0".

The reason for this is that the physical switch sends network packages for the native/default VLAN as untagged packages. ESXi forwards such packages to port groups that have no VLAN-ID set (i.e. VLAN-ID 0).

that's done the trick thank you!!!

One last question if you don't mind?

I installed an OVA/OVF which was Dell OpenManage Server Administrator. It's now responding and online but I cannot access the web interface. I was wondering if the ESXi firewall might have something to do with this? Or does the ESXi firewall only apply to the host?

Thanks again!

ESXi itself does not restrict traffic from and to VMs.

Okay issue is the VM then, thanks for all your help everyone 🙂
