In addition to PVC-based QoS, you can assign different levels of priority to different packets based on information
in the packets. To do this, click the Edit list of QoS Settings button. A window titled QoS Function will appear.
This window lets you set the priority for packets selected by any of the following criteria, alone or in combination:
• Destination. IP address and Netmask (address mask), FQDN (Fully Qualified Domain Name).
• Source. IP address and Netmask (address mask).
• Source MAC. Source MAC address.
• Destination MAC. Destination MAC address.
• Protocol (Transport). TCP, UDP, ICMP, or All.
• Dst Port/Scr Port (Destination port and/or source port). If protocol is set to TCP or UDP.
• Ethernet Type. The value in the 13th and 14th octets of an Ethernet frame.
• ALG. Triggering of a particular Application Layer Gateway (FTP, TFTP, H.323, IRC, MMS, GRE, PPTP, SIP, or
RTSP).
• 802.1D User Priority. Presence of a specified IEEE 802.1D user priority marker.

• Packet length Min/Max. Packet length between specified minimum and maximum numbers of octets.
• Priority. Set the priority of None, Low, Medium, or High.
Fragment packets' size of AF and BE traffic to be equal to the size of EF traffic: Enable this option and input a
packet size to have large Assured Forwarding (medium priority) and Best Effort (low priority) packets fragmented
so they will not uduly delay Expedited Forwarding (high priority) packets. The value you enter should be from 68
to 1492.
