command lets you set the QOS precedence for various flow
fields in IP traffic. You can set a precedence from 1 – 7 for the following IP fields:
• IP source address
• IP destination address
• Source TCP or UDP port
• Destination TCP or UDP port
• Type of Service (TOS) for the packet

that have a precedence of 1 are given first priority. The default priorities are as follows:
• destination port (1)
• destination address (2)
• source port (3)
• source IP address (4)
•TOS (5)
