Nexus 3064 many Q-in-Q tunnels on interface

[Tomasz Hinz]

Hello there,

On nexus 3064 I can do Q-in-Q with following config:

nterface g0/10
switchport
switchport mode dot1q-tunnel
switchport access vlan 222

but I don't know how to do many Q-in-Q incoming tunnels on one interface.

I receive VLAN 800-811 in Q-in-Q vlan 222

and VLAN 900-945 in Q-in-Q vlan 223

Is this passible on this switch ?

Thank you in advance !

I'm pretty sure it's not possible - I believe what you need is called selective q-in-q, which n3k cannot do.

Because I have confirmation from other source about that, now I'm sure that is not possible. Many thanks !

I've only worked with NX-OS 6 on Nexus 3064 - after reading Georg's post I browsed through NX-OS 7 docs for Nexus 3000 series and found (in the Interfaces Configuration Guide) that vlan mapping dot1q-tunnel is indeed available.
I have some unused 3064s around and I could test this when I get some time, but I think it's safe to say that what you need is possible with NX-OS 7...

Hello,

do you mean:

switchport vlan mapping 800-811 dot1q-tunnel 222

switchport vlan mapping 900-945 dot1q-tunnel 223

You need NX-OS 7.x for this command...
