Cat9300/9500 - Multiple selective QinQ on interface

[tomasgravvold]

Hi!

I have a case where I'd like to place an outer tag (with selective QinQ) on a range of vlan's, with several different outer tags, on the same interface:

Something like this:

switchport vlan mapping 8,75-76 dot1q-tunnel 100

switchport vlan mapping 8,75 dot1q-tunnel 101

switchport vlan mapping 8,76 dot1q-tunnel 102

..but it seems it's not possible the way I am doing it.

Is there any other way around this?

Hello @tomasgravvold ,

you are trying to configure something that is conceptually wrong

Try to see if different VLAN subsets can be mapped to different 802.1Q tunnel VLANs, in your case you would like to send traffic from VLANs 8 to all three tunnels and this is clearly unsupported.

The following might be supported :

switchport vlan mapping 8 dot1q-tunnel 100

switchport vlan mapping 75 dot1q-tunnel 101

switchport vlan mapping 76 dot1q-tunnel 102

There is no multiplying capability in QinQ a single inner VLAN has to be mapped to a single outer VLAN. This is my understanding.

Hope to help

Ok, i kind of suspected that, to be honest. The case is that we need to transport one vlan for management and one for data out to several corporate clients, via another provider. This provider adds different outer tags on the customers, and I want to avoid creating different vlans for all the customers.
