Use undo if-match to delete a match criterion. When defining match criteria, use the usage guidelines described in these subsections. Defining an ACL-based match criterion If the ACL referenced in the if-match command does not exist, the class cannot be applied to hardware. For a class, you can reference an ACL twice by its name and number, respectively, with the if-match command. Defining a criterion to match a destination MAC address You can configure multiple destination MAC address match criteria for a class. Defining a criterion to match a source MAC address You can configure multiple source MAC address match criteria for a class. Defining a criterion to match DSCP values • You can configure multiple DSCP match criteria for a class. All defined DSCP values are automatically sorted in ascending order. • To delete a criterion that matches DSCP values, the specified DSCP values must be identical with those defined in the criterion (the sequence may be different). Defining a criterion to match 802.1p priority in customer or service provider VLAN tags • You can configure multiple 802.1p priority match criteria for a class. All the defined 802.1p values are automatically arranged in ascending order. • To delete a criterion that matches 802.1p priority values, the specified 802.1p priority values in the command must be identical with those defined in the criterion (the sequence may be different). Defining a criterion to match IP precedence values • You can configure multiple IP precedence match criteria for a class. The defined IP precedence values are automatically arranged in ascending order. • To delete a criterion that matches IP precedence values, the specified IP precedence values in the command must be identical with those defined in the criterion (the sequence may be different). Defining a criterion to match customer network VLAN IDs or service provider network VLAN IDs • You can configure multiple VLAN ID match criteria for a class. The defined VLAN IDs are automatically arranged in ascending order. • You can configure multiple VLAN IDs in one command line. If the same VLAN ID is specified multiple times, the system considers them as one. If a packet matches one of the defined VLAN IDs, it matches the if-match clause. • To delete a criterion that matches VLAN IDs, the specified VLAN IDs in the command must be identical with those defined in the criterion (the sequence may be different).
