Planning an ACL application

Before creating and implementing ACLs, define the policies you want your ACLs to enforce, and understand how the ACL assignments will impact your network users.

NOTE:

IPv6 traffic leaving the switch on a given interface is filtered by the ACLs configured for inbound traffic on that interface. For this reason, an inbound packet will be denied (dropped) if it has a match with an implicit (or explicit) deny ipv6 any any in any of the inbound ACLs applied to the interface.
