Chapter 9 Configuring Authentication

Configuring Authentication Services

Configuring Authentication Services

Configuring authentication services consists of setting the appropriate parameters for the various AAA service options that can be used by the storage router. The storage router can use any or all of the supported services:

RADIUS

TACACS+

Local username database

Enable

Monitor

Use the procedures that follow to configure the storage router to use each of these services.

Note See the iSCSI driver readme file for details on configuring CHAP user names and passwords for iSCSI authentication.

RADIUS Servers

Use the commands in the following procedure to configure RADIUS authentication services.

 

Command

Description

Step 1

 

 

enable

Enter Administrator mode.

Step 2

 

 

radius-server host 10.6.0.53

Specify the RADIUS server to be used for authentication. For

 

 

example, specify the RADIUS server at 10.6.0.53 for use by the

 

 

storage router.

 

 

Because no port is specified, the authentication requests use the

 

 

default UDP port 1645. Global timeout and retransmit values are

 

 

also used.

 

 

See the Cisco SN 5400 Series Storage Router Command Reference

 

 

for more information about the radius-server host command.

Step 3

 

 

radius-server host 10.6.0.73

Specify additional RADIUS servers. For example, specify the

 

radius-server host 10.5.0.61

RADIUS servers at 10.6.0.73 and 10.5.0.61 as the second and third

 

RADIUS server to be used for authentication.

 

 

 

 

RADIUS servers are accessed in the order in which they are

 

 

defined (or for a specified server group, in the order they are

 

 

defined in the group).

Step 4

 

 

radius-server key rad123SN

Configure the global authentication and encryption key to be used

 

 

for all RADIUS communications between the SN 5428-2 and the

 

 

RADIUS daemon. For example, set the key to rad123SN.

 

 

This key must match the key used on the RADIUS daemon.
