Set Dscp Values For Egress Packets Based On Flow; Display Configured Class Maps And Match Criteria - Dell Force10 Z9000 Configuration Manual

In cases such as these, where class-maps with overlapping ACL rules are applied to different queues, use
the order
The order can range from 0 to 254. FTOS writes to the CAM ACL rules with lower order numbers (order
numbers closer to 0) before rules with higher order numbers so that packets are matched as you intended.
By default, all ACL rules have an order of 254.

Match-any Layer 3 flows may have several match criteria. All flows that match at least one of the match
criteria are mapped to the same queue since they are in the same class map. Setting a DSCP value from

value to all of the matching flows in the class-map. The Flow-based DSCP Marking feature allows you to
assign different DSCP to each match criteria CLASS-MAP mode using the option
command so that matching flows within a class map can have different DSCP values, as shown in

Figure 35-11. The values you set from CLASS-MAP mode override the value you QoS input policy DSCP
value, and packets matching the rule are marked with the specified value.
