VLAN QinQ Client Isolation

Thu Apr 07, 2022 4:53 pm

Hi @ all,

I am trying to use different CRS3xx Hardware in a FTTx setup. For this use case I am normally using Carrier Grade Equipment (Cisco and Waystream) but I am trying to integrate our older infrastructure into our new network design and practices. All the basic stuff is working fine but is still have problems with port security and client isolation (NNI and UNI).
Simplified Network design is as follows:

What I am trying to achieve is complete client to client isolation on all vlan and if possible, implement protocol filtering and dhcp snooping.
Is this even possible on CRS3xx Devices if I want to keep hardware offloading active?

I already tried to use Port Isolation in the Switch Menu but clients on the same vlan can still see each other.

Hopefully some of you are more specialized in this.
Thanks in advance!
Alex
