Configuring RADIUS Server Support for Switch Services

Configuring and Using RADIUS-Assigned Access Control Lists

1.Enter the ProCurve vendor-specific ID and the ACL VSA in the FreeRADIUS dictionary file:

VENDOR

HP

11

 

ProCurve (HP) Vendor-Specific ID

 

BEGIN-VENDOR

HP

 

 

 

ATTRIBUTE

HP-IP-FILTER-RAW 61 STRING

END-VENDOR

HP

 

 

ProCurve (HP) Vendor-Specific

Attribute for RADIUS-assigned ACLs

Note that if you were also using the RADIUS server to administer 802.1p (CoS) priority, you would also insert the ATTRIBUTE entries for these functions above the END­ VENDOR entry.

2.Enter the switch IP address, NAS (Network Attached Server) type, and the key in the FreeRADIUS clients.conf file. For example, if the switch IP address is 10.10.10.125 and the key is “1234”, you would enter the follow­ ing in the server’s clients.conf file:

client 10.10.18.12 nastype = other secret = 1234

Note: The key configured in the switch and the secret configured in the RADIUS server supporting the switch must be identical. Refer to the chapter titled “RADIUS Authentication and Accounting” in the

Access Security Guide for your switch.

3.For a given client username/password pair or MAC address, create an ACL by entering one or more ACEs in the FreeRADIUS “users” file. Enter the ACEs in an order that promotes optimum traffic management and conser­ vation of system resources, and remember that every ACL you create automatically includes an implicit deny in ip from any to any ACE. For example, suppose that you wanted to create identical ACL support for the following:

•a client having a username of “mobile011” and a password of “run101112”

•a client having a MAC address of 08 E9 9C 4F 00 19

The ACL in this example must achieve the following:

•permit http (TCP port 80) traffic from the client to the device at 10.10.10.101

•deny http (TCP port 80) traffic from the client to all other devices

•permit all other traffic from the client to all other devices

To configure the above ACL, you would enter the username/password and ACE information shown in figure6-6 into the FreeRADIUS users file.
