3Com MSR 30, MSR 50 manual Define Mpls EXP precedence matching rule

1786 CHAPTER 108: DEFINING CLASS COMMANDS

■if-match rule 1

■if-match rule 2

■traffic classifier classA operator or

■if-match rule 3

■if-match classifier classB

For a class, you can configure multiple commands which cannot be overwritten.

5Define DSCP matching rule.

■For a class, you can configure multiple commands which cannot be overwritten. The DSCP values specified by them are automatically arranged in ascending order. Only when the specified DSCP values are identical with those in the rule (sequence may be different) can the command be deleted.

■You may configure up to eight DSCP values in one command. If multiple DSCPs of the same value are specified, the system regards them as one. Relation between different DSCP values is "OR".

6Define 802.1p priority matching rule.

For a class, you can configure multiple commands which cannot be overwritten. The 802.1p priority values specified by them are automatically arranged in ascending order. Only when the specified 802.1p priority values are identical with those in the rule (sequence may be different) can the command be deleted.

You may configure up to eight 802.1p priority values in one command. If multiple 802.1p priorities of the same value are specified, the system regards them as one. Relation between different 802.1p priority values is "OR".

7Define inbound interface matching rule.

■For a class, you can configure multiple commands which cannot be overwritten.

■Before defining this matching rule, make sure that the interface exists. If the specified interface is a dynamic one, removing the interface can delete the rule.

■Supported interfaces: ATM, Ethernet, serial port, Tunnel, VT, etc.

8Define IP precedence matching rule

■For a class, you can configure multiple commands which cannot be overwritten. When the command is configured, the ip-precedence values will be arranged automatically in ascending order. Only when the specified ip-precedence values are identical with those in the rule (sequence may be different) can the command be deleted.

■You may configure up to eight ip-precedence values in one command. If multiple ip precedence of the same value are specified, the system regards them as one. Relation between different ip-precedence values is "OR".

9Define MPLS EXP precedence matching rule.

■For a class, you can configure multiple commands which cannot be overwritten. When the command is configured, the MPLS EXP precedence values will be arranged automatically in ascending order. Only when the
