Hi all,
New to the forums but I've done a bit of searching and can't seem to find the scenario I'm looking to solve for. I have an EX2200 on which I need to take incoming untagged traffic on multiple ports, mark the same inner VLAN on each but different outer VLANs on each port, to be conditioned to go out with the same inner VLAN on multiple trunk ports facing northbound.
For example:
Port 1: Trunk port for "Store A" VLAN 50
Port 2: Trunk port for "Store B" VLAN 50
Port 3: Access port for "Store A" VLAN 50
Port 4: Access port for "Store B" VLAN 50
(etc).
My expected behavior is that for "Store A," Port 3 receives untagged traffic, adds VLAN 50 and any local S-Tag (ex. 1000), then pops off the S-Tag on the way out the trunk port (1) so that it leaves the switch as VLAN 50. "Store B" should have the same behavior but use a different S-Tag to differentiate the traffic.
I can add a single VLAN tag to untagged traffic when it comes in but not sure how to differentiate the traffic between the two separate customers/ports that use the same VLAN ID. I've also looked into Private VLANs but I wasn't able to find a way to use the same VLAN ID northbound for two promiscuous ports.
Any suggestions on how to accomplish that would be greatly appreciated!
Cheers!
