Options for assigning priority
Priority control options for TCP or UDP packets carrying a specified TCP or UDP port number include:
802.1p priority
DSCP policy: Assigning a new DSCP and 802.1p priority
For a given TCP or UDP port number, you can use only one of the above options at a time. However, for different port numbers, you can use different options.
You can have up to 250 rules maximum for all TCP or UDP ports with assigned priorities.
