About Network Access Filters
A NAF is a named group of any combination of one or more of the following
network elements:
• IP addresses
• AAA clients (network devices)
• Network device groups (NDGs)
Using a NAF to specify a downloadable IP ACL or NAR—based on the AAA
clients by which the user may access the network—saves you the effort of listing
each AAA client explicitly.
• NAFs in downloadable IP ACLs—You can associate a NAF with specific
ACL contents. A downloadable IP ACL consists of one or more ACL contents
(sets of ACL definitions) that are associated with either a single NAF or, by
default, “All-AAA-Clients”. This pairing of ACL content with a NAF permits
Cisco Secure ACS to determine which ACL content is downloaded according
to the IP address of the AAA client making the access request. For more
information on using NAFs in downloadable IP ACLs, see About
Downloadable IP ACLs, page 5-8.
