What are the default DSCP codepoint values?
The DSCP Policy Table associates an 802.1p priority with a specific ToS byte codepoint in an IPv4 packet. This enables you to set a traffic management policy that operates independently of 802.1Q VLAN-tagging. In the default state, most of the 64 codepoints do not assign an 802.1p priority, as indicated by “No-override” value in the table below. You can use the show qos dscp-map command to list the current DSCP Policy table. Use the qos dscp-map command to change the codepoint priority assignments, and assign optional names to the codepoints.
