Qos - D-Link dsl-504T User Manual

QoS

QoS or Quality of Service is used to assign priority for qualified traffic that passes through the Router's wired
interfaces (LAN and WAN). The Router uses four priority levels with "1" being the highest priority while "4" is
the lowest.
The IGMP Proxy/Snooping is disabled by default. This setting will not allow IGMP (Internet Group
Management Protocol) packets to be forwarded from the WAN to the LAN for the purpose of IGMP snooping, or
from the LAN to the WAN to request multicast group membership (IGMP Proxy). IGMP is used to manage
multicasting (streaming radio for example is a multicast), most users will not need to enable this. Some ISPs
use IGMP to perform remote configuration for client devices, such as the Router. If unsure, check with the
service provider. To enable IGMP service to the LAN interface, select Enabled and click the Apply button
To set QoS for the router, first click the PortMapping QoS check box in the middle of the window. This will
open the following window. Then select the PVC to associate with the corresponding port and choose a priority
for this combination. The user may also enable IGMP Proxy/Snooping for any PVC at the top of the window by
choosing the PVC from the pull-down menu and clicking the Enabled radio button and set a maximum
Bandwidth in kbps from Auto to 64 using the drop-down menu. Click Apply to set the configuration.
QoS configured in the QoS menu applies only to data traffic on the Ethernet LAN and the WAN (ADSL)
ports.
