HP V1910 manual Define a match criterion to match Dscp values, Does not overwrite the previous one

Item		Description
		Define a match criterion to match DSCP values.
		If multiple such match criteria are configured for a class, the new configuration
		does not overwrite the previous one.
DSCP		You can configure up to eight DSCP values each time. If multiple identical DSCP
		values are specified, the system considers them as one. The relationship
		between different DSCP values is OR. After such configurations, all the DSCP
		values are automatically arranged in ascending order.
		Define a match criterion to match IP precedence values.
		If multiple such match criteria are configured for a class, the new configuration
		does not overwrite the previous one.
IP Precedence		You can configure up to eight IP precedence values each time. If multiple
		identical IP precedence values are specified, the system considers them as one.
		The relationship between different IP precedence values is OR. After such
		configurations, all the IP precedence values are automatically arranged in
		ascending order.
		Define a match criterion to match the customer 802.1p precedence values.
		If multiple such match criteria are configured for a class, the new configuration
		does not overwrite the previous one.
Customer 802.1p		You can configure up to eight 802.1p precedence values each time. If multiple
		identical 802.1p precedence values are specified, the system considers them
		as one. The relationship between different 802.1p precedence values is OR.
		After such configurations, all the 802.1p precedence values are automatically
		arranged in ascending order.
		Define a match criterion to match a source MAC address.
	Source MAC	If multiple such match criteria are configured for a class, the new configuration
		does not overwrite the previous one.
		A source MAC address match criterion is significant only to Ethernet interfaces.
MAC
		Define a match criterion to match a destination MAC address.
		If multiple such match criteria are configured for a class, the new configuration
	Destination MAC	does not overwrite the previous one.
		A destination MAC address match criterion is significant only to Ethernet
		interfaces.
		Define a match criterion to match service VLAN IDs.
		If multiple such match criteria are configured for a class, the new configuration
		does not overwrite the previous one.
		You can configure multiple VLAN IDs each time. If the same VLAN ID is
VLAN	Service VLAN	specified multiple times, the system considers them as one. The relationship
		between different VLAN IDs is logical OR. After such a configuration. You can

specify VLAN IDs in two ways:

∙ Enter a range of VLAN IDs, such as 10-500. The number of VLAN IDs in the range is not limited.

∙ Specify a combination of individual VLAN IDs and VLAN ID ranges, such as 3, 5-7, 10. You can specify up to eight VLAN IDs in this way.
