Hi all,

Can someone please tell me the reason we have a VLAN10 tag on the WAN port for UFB connections?

Our ISP of choice can do with or without and our preference is without in case our client ever factory resets the router they will still get internet ( we dont use consumer ISP supplied routers )

I understand the VLAN on the LAN side, just not the WAN side.

If someone can please explain in layman's terms that would be awesome ( my google fu has failed me ).

Cheers

John

Hi, by using the vlan tag means you also have access to the traffic priority tag, not that many if anyone uses it, thats pretty much it.

I have my Edgerouter 4 set up to use the priority tags - I have it mapping the DSCP bits in the IP headers so my high priority outbound packets will be sent on CIR bandwidth. This is the line in my configuration that does it:

set interfaces ethernet eth0 vif 10 egress-qos '1:5 2:5 3:5 4:5 6:5 7:5'

The ER4 will be mapping that config to something in the Linux TCP/IP config that actually implements it, but I have never looked at how it is done. When I did it originally in my ERLite, I tested it and it seemed to be working.
