Hardware match order of ACL subrules
S6500 Series
When one ACL is configured with several subrules, the one with
the most precisely defined range is chosen as the first hardware
match order. If subrules are defined with the same range, the last
configured one will be first matched. For instance, one ACL 3000
has two subrules: rule0 and rule1,
rule0 is defined as “rule 0 permit ip source 1.1.1.1 0.0.255.255
destination 2.2.2.2 0.0.255.255”, and rule1 is defined as “rule 1
permit ip source 1.1.1.1 0.0.0.255 destination 2.2.2.2
0.0.0.255”.Since the range of rule1 is more precise, it will be
matched first.
