Hi,

I have a CRS125. Port 1 is the masterport for all the other ports, so it's working at wire speed.

Now I have one device that is using multiple VLANs, and I need to connect it to the CRS125 at port 8. However, only VLAN25 should connect to the switch, all the other VLANs on that network cable should be ignored.

So the VLAN25 tags should be removed when the packages are entering the switch into port 8 (and be tagged VLAN25 when they leave port 8 ).

How can I do this?
Can I still use the switch chip for this port?

Thanks!

You can do ingress vlan translation, i.e customer VID=100 and new customer VID=25.
