Motorola Enterprise Series Routers, 6161252-00-01 manual Priority Queuing TOS bit

WAN Configuration 2-25

•Priority – This is the Quality of Service setting for the rule, based on the TOS bit information. Select assure, expedite, or off (default) from the pop-up menu. The following table outlines the TOS bit settings and behavior:

QoS Setting	TOS Bit Value	Behavior
off	TOS=000	This custom rule is disabled. You can activate it by selecting one of
		the two settings below. This setting allows you to pre-define flows
		without actually activating them.
assure	TOS=001	Use normal queuing and throughput rules, but do not drop packets
		if possible. Appropriate for applications with no guaranteed delivery
		mechanism.
expedite	TOS=101	Use minimum delay. Appropriate for VoIP and video applications.

•Numerical Protocol – If you select “Other” protocol, this field appears for you to provide its actual protocol number, with a range of 0 – 255.

•Direction – Choose outbound (default), inbound, or both from the pop-up menu.

•Start Port – For TCP or UDP protocols, you can optionally specify a range of ports. Enter the starting port here.

•End Port – Enter the ending port here.

•Inside IP Address/Netmask – For outbound flows, specify an IP address and subnet mask on your LAN. For inbound flows, this setting is ignored.

•Outside IP Address/Netmask – If you want traffic destined for and originating from a certain WAN IP address to be controlled, enter the IP address and subnet mask here. If you leave the default all-zeroes, the outside address check is ignored.

For outbound flows, the outside address is the destination IP address for traffic; for inbound packets, the outside address is the source IP address.

When you are finished, select COMMIT and press Return. You will be returned to the Diffserv Options screen and your settings will take effect.

Priority Queuing (TOS bit)

Motorola Netopia® Embedded Software Version 8.7.4 offers the ability to prioritize delay-sensitive data over the WAN link on DSL connections.

Certain types of IP packets, such as voice or multimedia packets, are sensitive to latency introduced by the network. This means that if such packets are not received rapidly, the quality of service degrades. If you expect to route significant amounts of such traffic you can configure your router to prioritize this type of traffic using the priority queuing feature.

To configure your router to prioritize delay-sensitive data, navigate to the Advanced Connection Options screen in the console menu.
