QoS at Speedlink 5501

Hello

Sorry, this is a DSL-Router and not a switch. I didn't find a group for Routers. But it has simmilar switch functionality

I have a device which is configured as followed (factory settings):



I can't interpret/understand the column "Bandwith Allocation" and "QoS Interface"
- make it sense to define "0 Percent"??
- there are double entries??
- what means "PPPoE" -> VLAN 7 -> ATM 1/32 -> DSL" and what the difference to "DHCP -> VLAN 8 -> ATM 1/32 -> DSL"?



Should "speech" not be EF class for optimal VoIP results?

Thanks for your help

Michael
