# Policy Rule Precedence

Because of the flexibility in creating policy lists and classifier groups, you can configure a classifier group that has multiple policy rules.

If a classifier group has multiple rules, the router uses the rules according to their precedence—not in the order in which you created the rules. The first rule listed (the forward rule) for a policy list type has the highest precedence and the last rule has the lowest. The precedence is based on the order in which the router performs rules. Rules are performed in order from lower to higher precedence. In the event of a conflict, a higher precedence rule overrides the lower precedent rule.

The precedence of rules is important if you want a specific rule to be applied. For example, if an IP policy list has both a rate-limit-profile rule (which specifies a color) and a color rule in the same classifier-group, the color specified by the color rule is always used rather than the color implied in the rate-limit-profile rule (the color rule has a higher precedence).

Table 1 lists the policy rule commands that you can use for each type of policy list. The table lists the rules in their order of precedence.

| Note: The ES2 10G Uplink LM and the ES2 10G LM support only IP, MPLS, and VLAN interfaces.

traffic-class | traffic-class | traffic-class | user-packet- class | mark | traffic-class | user-packet- class | traffic-class

| Note: The commands listed in this section replace the Policy List Configuration mode versions of the commands. For example, the color command replaces the Policy List Configuration mode version of the color command. The original command may be removed completely in a future release.
