Configuring Any RADIUS Server for Downloadable Access Lists
You can configure any RADIUS server that supports Cisco IOS RADIUS VSAs to send user-specific
access lists to the adaptive security appliance 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, 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 adaptive security appliance. 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 access list 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 access lists that are sent in the cisco-av-pair attribute,
see the documentation for your RADIUS server.
On the adaptive security appliance, the downloaded access list name has the following format:
AAA-user-username
The username argument is the name of the user that is being authenticated.
The downloaded access list on the adaptive security appliance consists of the following lines. Notice the
order based on the numbers identified on the RADIUS server.
access-list
access-list
access-list
access-list
access-list
Downloaded access lists have two spaces between the word "access-list" and the name. These spaces
serve to differentiate a downloaded access list from a local access list. In this example, "79AD4A08" is
a hash value generated by the adaptive security appliance to help determine when access list definitions
have changed on the RADIUS server.
