LABEL	DESCRIPTION
Port	This field displays the index number of a port on the Switch.
*	Settings in this row apply to all ports.
	Use this row only if you want to make some settings the same for all ports.

	based on the color they are marked via TRTCM.
green	Specify the DSCP value to use for packets with low packet loss priority.
yellow	Specify the DSCP value to use for packets with medium packet loss priority.
red	Specify the DSCP value to use for packets with high packet loss priority.
Apply	Click Apply to save your changes to the Switch’s run-time memory. The
