Quickly listing non-default codepoint settings

The DSCP Policy Table in Differentiated Services Codepoint (DSCP) mapping, lists the switch’s default codepoint/priority settings. If you change the priority of any codepoint setting to a non-default value and then execute write memory, the switch will list the non-default setting in the show config display. For example, in the default configuration, the following codepoint settings are true:

If you change all three settings to a priority of 3, and then execute write memory, the switch will reflect these changes in the show config listing:
