16.7.2 Traffic Priority
If you click the Quality of Service link in the Advanced screen and then click Traffic Priority in the left submenu,
the following screen will appear. This screen allows you to configure QoS to prioritize input and output traffic.
Traffic Priority manages and avoids traffic congestion by defining inbound and outbound priority rules for each
device on the Router. These rules determine the priority that packets, traveling through the device, will receive. QoS
parameters (DSCP marking and packet priority) are set per packet, on an application basis.
QoS can be configured using flexible rules, according to the following parameters:
• Source/destination IP address, MAC address, or host name
• Device
• Source/destination ports
• Limit the rule for specific days and hours
The Router supports two priority marking methods for packet prioritization:
• DSCP
• 802.1p Priority
The matching of packets by rules, also known as Stateful Packet Inspection is connection-based and uses the
Router’s firewall mechanism. Once a packet matches a rule, all subsequent packets with the same attributes receive
the same QoS parameters, both inbound and outbound.
To set up a traffic priority rule, click the adjacent New Entry link for the input/output device you want to configure.
