Adding a Network ACL Rule (Custom Priorities)

Scenarios

If you want a new rule to have a higher or lower priority than a specific rule, you can insert the new rule above or below the specific rule.

As shown in Table 1, there are two custom inbound rules (rule A and rule B) and one default rule. The priority of rule A is 1 and that of rule B is 2. The default rule has the lowest priority. If you want rule C to be applied earlier than rule B, you can insert rule C above rule B. After rule C is added, the priority of rule C is 2, and that of rule B is 3.

**Table 1** Custom priorities
Priorities (Rules A and B)		Priorities (Rules A, B, and C)
Custom rule A	1	Custom rule A	1
--	--	Custom rule C	2
Custom rule B	2	Custom rule B	3
Default rule	*	Default rule	*
