1-6specified protocol type are of the same precedence level. Compare packets against the rule withthe highest precedence.2) In case of a tie, look at the source IPv6 address prefixes. Then, compare packets against the ruleconfigured with a longer prefix for the source IPv6 address.3) If the prefix lengths for the source IPv6 addresses are the same, look at the destination IPv6address prefixes. Then, compare packets against the rule configured with a longer prefix for thedestination IPv6 address.4) If the prefix lengths for the destination IPv6 addresses are the same, look at the Layer 4 portnumber ranges, namely the TCP/UDP port number ranges. Then compare packets against therule configured with the smaller port number range.5) If the port number ranges are the same, compare packets against the rule configured first.The comparison of a packet against an ACL stops immediately after a match is found. The packet isthen processed as per the rule.IPv6 ACL StepRefer to IPv4 ACL Step.Effective Period of an IPv6 ACLRefer to Effective Period of an IPv4 ACL.ACL ApplicationACLs are widely used in technologies. One typical application is to apply different types of ACLs fortraffic filtering. For details, refer to ACL Application for Packet Filtering.In addition, ACLs can be used in such fields as routing, security, and QoS. For configuration details,refer to the related parts of this configuration manual.
