• Transport protocol (TCP, UDP, or All)
• Destination port and/or source port (if protocol is set to TCP or UDP)
• Presence of a specified IEEE 802.1D user priority marker
• IEEE 802.3 Type/Length value (the value in the 13th and 14th octets of an Ethernet frame)
• Presence of a specified IEEE 802.1Q virtual LAN (VLAN) ID
• Packet length between specified minimum and maximum numbers of octets.
• Presence of a specified DSCP (Diffserv Code Point) value (one kind of QoS marker)
