I have a few Dell 6224 and a bunch of 3524's and some 5324 - with the latest firmware.
I need to configure QinQ between ports, conveniently called "Customer port" on the 35xx and the 53xx, and it works like a charm there, can even do the config right from GUI - set the port to customer mode, and tag the VLAN to use for the transport. (ingress data tag data is ignored and a outer heading added for transport, egress strips the outer tag).
But, the 62xx will not play nicely - it has what is called "double-VLAN" or dvlan-tunnel, which is supposed to provide the same features. The manual is junk and support haven't provided an answer in days now. The best online info I could find was at community.dell.com, but that still doesn't tell me the correct way of using dvlan-tunnel - as soon as I enable it on any interface, all other trunks stops forwarding.
Does anyone know how to configure this correctly without bringing down the rest of the switch, when you have a mix of normal q-tags and need some q-in-q for just a port or two?
