ACLs
214
Managed Switches
Note that the order of the rules is important: When a packet matches multiple rules, the first
rule takes precedence. Also, once you define an ACL for a given port, all traffic not
specifically permitted by the ACL is denied access.
Figure 24. IPv6 ACLs
The script in this section shows you how to set up an IPv6 ACL with the following three rules:
• Rule-1. Permits every traffic to the destination network 2001:DB8:C0AB:AC14::/64.
• Rule-2. Permits IPv6 TELNET traffic to the destination network
2001:DB8:C0AB:AC13::/64.
• Rule-3. Permits IPv6 HTTP traffic to any destination.
