Add Network Traffic Class Rule The screen creates a traffic class rule to classify the upstream traffic, assign queuing priority and optionally overwrite the IP header TOS byte. A rule consists of a class name and at least one condition below. All of the specified conditions in this classification rule must be satisfied for the rule to take effect. Click 'Save/Apply' to save and activate the rule. Traffic Class Name: Assign Priority and/or IP Precedence and/or Type Of Service for the class If non-blank value is selected for 'IP Precedence' and/or 'IP Type Of Service', the corresponding TOS byte in the IP header of the upstream packet will be overwritten by the selected value. Priority: Low Medium High IP Precedence: 0 1 2 3 4 5 6 7 IP Type Of Service: Normal Service Minimize Cost Maximize Reliability Maximize Throughput Minimize Delay Specify Traffic Conditions for the class Enter the following conditions either for IP layer or for the IEEE 802.1p priority. Protocol: TCP/UDP TCP UDP ICMP Source IP Address: Source Subnet Mask: Source Port (port or port:port): Destination IP Address: Destination Subnet Mask: Destination Port (port or port:port): 802.1p Priority: 0 1 2 3 4 5 6 7
