SFP WAN "ISP load" graph is accouting the wrong thing
My setup is:
There is a fiber SFP SFU ONU device on the SFP slot, a PPPOE connection is established there on internet vlan nnnn.
The ISP also pushes other traffic on this port, namely a multicast stream for IPTV, it is always in the 5mbit range.
For some reason the router appears to be accounting this multicast stream as "ISP load" which I guess is because the accouting is been done on the entire SFP device "aka eth0" and not on "pppN" or maybe "eth0.nnnn" where the actual internet traffic is going.
Nobody is subscribed to that multicast stream, it is esentially rendering the ISP load graph unreliable because it is not counting what it should.
