1. Determine whether the DSCP codepoints that you want to use to mark matching packets already

have an 802.1p priority assigned, which could indicate use by existing applications (show

qos dscp-map command). This is not a problem if the configured priorities are acceptable

for all applications that use the same DSCP.

Note that a DSCP codepoint must have an associated priority before you can use it to mark

matching packets.

2. Configure the priorities for the DSCPs you want to use to mark packets.
