The matching rules of the source MAC address are only meaningful for the policies in inbound direction
and the interface of Ethernet type.
5) Define the inbound interface matching rule of a class
Perform the following configurations in class view.
Table 1-6 Define/delete the inbound interface matching rule of a class
Operation Command
Define the inbound interface
matching rule of a class if-match [ logic-not ] inbound-interface type number }
Delete the inbound interface
matching rule of a class undo if-match [ logic-not ] inbound-interface type number
6) Define the DSCP matching rule
The differentiated services code point (DSCP) is a refined field from the 6 high bits of
ToS bytes in IP header by IETF DiffServ workgroup.In the solution submitted by
DiffServ, services are classified and traffic is controlled according to service
requirements at the network ingress. Simultaneously, DSCP is set. Communication
(including resource allocation, packet discard policy, etc.) is classified and served on
the basis of the grouped DSCP values
You can set classified matching rules according to DSCP values.
Perform the following configurations in class view.
Table 1-7 Define/delete DSCP matching rule
Operation Command
Define DSCP matching rule if-match [ logic-not ] ip-dscp value [ value ] …
Delete DSCP matching rule undo if-match [ logic-not ] ip-dscp value [ value ] …
7) Define the IP precedence matching rule
Perform the following configurations in class view.
Table 1-8 Define/delete ip precedence matching rule
Operation Command
Define IP precedence matching rule if-match [ logic-not ] ip-precedence value [ value ] …
Delete IP precedence matching rule undo if-match [ logic-not ] ip-precedence …
