QinQ Untagging Double VLANs

[schat]

Hello, I'm trying to set up a vlan config as follows. My upstream requires using vlan 119 tagged out port 4. I would like to have ports on the switch separated in their own vlans that are then trunked into vlan 119. In the picture, the T on port 4 for vlan 31 and 32 should be double tagged with vlan 119 on the outside. I've tried every combination that I can think of and haven't been able to make it work. I've reviewed all the relevant posts on the forum and I am at a loss. I have this configuration working with two Mikrotik devices. Is this kind of thing possible with Netonix?

I'm running 1.5.0 on a WS-12-250-DC

To summarize, I'm looking to take different untagged ports and double tag them individually out another port. Thank you in advance.

Edit: To clarify, I need QinQ, not Double Tag

1) Do you want a double tag? i.e a 0x8100 tag inside of a 0x8100 tag? That would be the D option.

2) Or do you want a QinQ tag? i.e a 0x8100 tag inside of a 0x81a8 tag? That would be the Q option.

3) This switch can't add two tags. Tagged traffic that ingresses a Q or D port will have the respective tag added. It can then egress the switch on any T port for that vlan.

Example. Port 1 T119. Port 2 D 119. Packets tagged on any vlan, i.e 31 and 32, that enter port 2 will have a second 0x8100 tag added to them and they will egress out port 1 with the outside tag and the inside tag. (Change port 2 to Q if thats the outside tag you want).

I need a QinQ tag. In my picture, traffic coming in port 7 is untagged, I need that traffic leaving port 4 with QinQ 119 on outer and 31 on inner.

That's not how it works.

In your picture/screen grab above a packet coming in port 7 Untagged would leave port 4 Tagged VLAN ID 31.

Even if you put a Q on port 4 instead if T but had a U on Port 7 it would not work that way.

Okay, I gather that what I'm trying to do is not possible on this switch. Is that correct?

From what I understand you want to do is not possible with any Layer 2 switch

VLAN is an IEEE Standard called 802.1Q, we follow the standard

We also do QinQ which is also an IEEE Standard called 802.1ad

It's possible to double tag a port with several switch but can't currently be done on Netonix. It's ether a S-VLAN or C-VLAN, not both.

If I understand well, you could simple use Q with VID 119 and remove other config. Any VLAN including 31 and 32 would be allow and encapsulated with QinQ VID 119. A schema would help better with other device and for what is use VID31 and VID32.

@Chris, what he ask follow standard, he would like to use both 802.1Q and 802.1ad at the same time on port 4 so
VID 31 & VID32 tagged (allowed) with 802.1Q standard and on the same port and immediatly after, add QinQ VID 119 with 802.1ad standard.

Maybe an easy way to configure it out would be for QinQ to beavior (in GUI) like a trunk so, choose which vlan are allowed inside the QinQ. Would just need to choose if a port is native (untage) and, if yes, witch one. Anyway, it don't really make sense to mix Tagged VLAN with QinQ (like currently done on GUI) since a QinQ should just encapsulate every allowed VLAN on the port with the S-VLAN.

Yes, this


My use case is this; I have a remote site with a fiber connection. Over that fiber peering, I must use a vlan for that site to differentiate other sites on that fiber network. At the site, I have customers with direct CAT5 connections as well as wireless equipment for use in our network. I would like to be able to connect those customers and the fiber backbone directly to a Netonix and have that be the only piece of equipment needed.

By the way, I love the Netonix products and use them extensively all over our network. They really have been great!

Can someone confirm that I cannot do this config with the current software of this switch?
