Dot1q-tunnel equivalent

Hi Team,

Is it possible to implement something similar to switchport mode dot1q-tunnel in Cisco land on a cnMatrix tower platform? In Netonix land it’s called “double tagging”.

In practical terms, it slaps an outter tag on all ingress packets, and retains the ingress tag as an inner tag.


Q-in-Q functionality is not supported on cnmatrix.

Hello, QinQ will be supported in 4.3, to be released late April/early May.

Hi Tam, now that this is supported, is there any documentation on how to configure it?

Go to support portal, see release notes document, there is an example of qinq configuration cnMatrix-EXTX Release Notes - 4.3-r3.pdf
