For more information about creating downloadable ACLs and associating them with users, see the user
guide for your version of Cisco Secure ACS.
On the ASA, the downloaded ACL has the following name:
#ACSACL#-ip-acl_name-number
The acl_name argument is the name that is defined on Cisco Secure ACS (acs_ten_acl in the preceding
example), and number is a unique version ID generated by Cisco Secure ACS.
The downloaded ACL on the ASA consists of the following lines:
access-list #ACSACL#-ip-asa-acs_ten_acl-3b5385f7 permit tcp any host 10.0.0.254
access-list #ACSACL#-ip-asa-acs_ten_acl-3b5385f7 permit udp any host 10.0.0.254
access-list #ACSACL#-ip-asa-acs_ten_acl-3b5385f7 permit icmp any host 10.0.0.254
access-list #ACSACL#-ip-asa-acs_ten_acl-3b5385f7 permit tcp any host 10.0.0.253
access-list #ACSACL#-ip-asa-acs_ten_acl-3b5385f7 permit udp any host 10.0.0.253
access-list #ACSACL#-ip-asa-acs_ten_acl-3b5385f7 permit icmp any host 10.0.0.253
access-list #ACSACL#-ip-asa-acs_ten_acl-3b5385f7 permit tcp any host 10.0.0.252
access-list #ACSACL#-ip-asa-acs_ten_acl-3b5385f7 permit udp any host 10.0.0.252
access-list #ACSACL#-ip-asa-acs_ten_acl-3b5385f7 permit icmp any host 10.0.0.252
access-list #ACSACL#-ip-asa-acs_ten_acl-3b5385f7 permit ip any any
Configuring Any RADIUS Server for Downloadable ACLs
You can configure any RADIUS server that supports Cisco IOS RADIUS VSAs to send user-specific
ACLs to the ASA in a Cisco IOS RADIUS cisco-av-pair VSA (vendor 9, attribute 1).
In the cisco-av-pair VSA, configure one or more ACEs that are similar to the access-list extended
command (see command reference), except that you replace the following command prefix:
access-list acl_name extended
with the following text:
ip:inacl#nnn=
The nnn argument is a number in the range from 0 to 999999999 that identifies the order of the command
statement to be configured on the ASA. If this parameter is omitted, the sequence value is 0, and the
order of the ACEs inside the cisco-av-pair RADIUS VSA is used.
The following example is an ACL definition as it should be configured for a cisco-av-pair VSA on a
RADIUS server:
ip:inacl#1=permit tcp 10.1.0.0 255.0.0.0 10.0.0.0 255.0.0.0
ip:inacl#99=deny tcp any any
ip:inacl#2=permit udp 10.1.0.0 255.0.0.0 10.0.0.0 255.0.0.0
ip:inacl#100=deny udp any any
ip:inacl#3=permit icmp 10.1.0.0 255.0.0.0 10.0.0.0 255.0.0.0
For information about making unique per user the ACLs that are sent in the cisco-av-pair attribute, see
the documentation for your RADIUS server.
On the ASA, the downloaded ACL name has the following format:
AAA-user-username
