Access port membership based on outer+inner VLAN tag - Catalyst 4500-X

Hello,

I am exploring options to assign access ports membership based on outer and inner tag. I am trying to achieve an architecture where the [outer tag and the inner tag] defines the broadcast domain membership of the access ports.

to give an example, the outer tag + inner tag combination of 10+100 will only forward layer 2 traffic to ports 1 and 2 where as outer tag + inner tag combination of 10+200 will forward layer 2 traffic to port 3 only. This way a broadcast frame for customer#1 on outer+inner tag 10+100 will not be forwarded to 10+200.

Frames on the access ports can be sigle tagged on not tagged at all.

Any help will be much appreciated. for switching I am using 4500X. please see the schematic attached.

Soooooo, what seems to be the problem? 
and what do you mean bu inner tag/outer tag, it's really confusing (with all your 10+100 thing)


Put it like this, what is your desired setup? What do you want with your setup?

It seems he have double 802

It seems he have double 802.1q tagged packets (a.k.a. Q in Q).

See IEEE 802.1Q-in-Q VLAN Tag Termination for more.
