Switching

I guess you forgot: set interfaces xe-0/0/0 native-vlan-id 1 And you should probably: set vlans qinq-100 switch-options no-mac-learning At the NNI, you will receive double-tagged frames (maybe the laptop doesn't like them). ------------------------------ ...

We connected the laptops for testing. Customer switch was not connected. Switch model is qfx5120 running 23.4R2. Below is the applied configuration, set interfaces xe-0/0/0 flexible-vlan-tagging set interfaces xe-0/0/0 encapsulation extended-vlan-bridge ...

you cannot really rely on the in/out bytes/packets values per unit on EX/QFX did you try with two real devices at each side ? maybe post the actual real content of both interfaces and vlan definition and what is the model of the switch btw? ...

Hi Oliver, Thanks for your continuous support. We applied the recommended configuration changes and connected a test laptop to the UNI port while generating continuous ICMP requests. Both the UNI and NNI ports successfully learned the MAC addresses. ...

Yes. And at the UNI side (xe-0/0/0), change this, too: vlan-id-list 1-50 At the NNI side you'll obtain dot1q outer 100 + inner 1. ------------------------------ Olivier Benghozi ------------------------------

Thanks Oliver for the clarification. Could you please let me know how we can include untagged traffic. Basically I want to consider untagged traffic as vlan 1 ( native vlan) and add outer tag as we are doing it for tagged traffic. The following commands ...

Correct, in the vlan definition, the vlan-id is not defined for the S-VLAN. It's defined in the unit on the NNI, and nowhere on the UNI (but uses the unit number). mac-learning should be disabled ; not mandatory, but useful and relevant, as it's completely ...
