This example uses the VSA attribute 61 for configuring RADIUS-assigned IPv4 ACL support on FreeRADIUS for two different client identification methods (username/password and MAC address).
Procedure
Enter the vendor-specific ID and the ACL VSA in the FreeRADIUS dictionary file:
Configuring the VSA for RADIUS-assigned IPv4 ACLs in a FreeRADIUS server
Enter the switch IPv4 address, NAS (Network Attached Server) type, and the key used in the FreeRADIUS
clients.conf file. For example, if the switch IP address is 10.10.10.125 and the key ("secret") is "1234", you would enter the following in the server's
clients.conf file:
Switch identity information for a freeRADIUS application
For a given client username/password pair, create an ACL by entering one or more IPv4 ACEs in the FreeRADIUS "users" file. Remember that the ACL created to filter IPv4 traffic automatically includes an implicit
deny in ip from any to any ACE (for IPv4). For example, to create ACL support for a client having a username of "User-10" and a password of "auth7X". The ACL in this example must achieve the following:
Permit http (TCP port 80) traffic from the client to the device at 10.10.10.117.
Deny http (TCP port 80) traffic from the client to all other IPv4 addresses.
Deny Telnet (TCP port 23) traffic from the client to any IPv4 address.
Permit all other IPv4 traffic from the client to all other devices.
