Cisco Secure ACS 3.3.2 or ACS 4.0

CiscoWorks Wireless LAN Solution Engine 2.13


Note This document applies to the Cisco Secure ACS versions listed above only. Non-Cisco applications are not supported.


ACS TACACS+ Setup for WLSE

To set up ACS TACACS+ for WLSE, you need to perform the following steps:

1. Add WLSE as a AAA client in ACS.

2. Set up the ACS group for WLSE.

3. Log in to WLSE and select the TACACS+ authentication module.

Procedure


Step 1 Log in to ACS with the admin user ID.

Step 2 Click Network Configuration on the left panel, then click Add Entry.

Step 3 In the Add AAA Client form, enter the following information:

AAA Client Hostname

AAA Client IP Address (Use your WLSE IP address.)

Key (You must either record or remember the key to configure WLSE.)

Authenticate Using TACACS+ (Cisco IOS)

Step 4 Click Submit.

Step 5 Click Interface Configuration on the left panel, then click TACACS+ (Cisco IOS).

Step 6 Under New Services, in the Service field, enter WLSE (case sensitive) and enter IP in the Protocol field, then click Submit.

You now need to set up the ACS group for WLSE.

Step 7 Click Group Setup. Select the group you will create for the WLSE users. Optional: Select a group ID and rename the group.

Step 8 Click Edit Settings. At the bottom of the TACACS+ Settings section, check the WLSE IP and Custom Attributes checkboxes. In the Custom Attributes field, enter the following parameters, then click Submit + Restart.

cmd=groups

cmd-arg="System Admin"


Note WLSE supports multiple user groups for a given user. In this case, the user will have combined privileges. The format to configure multiple group privileges for a given user is cmd-arg="Role1","Role2","Role3".


In this example, cmd-arg="System Admin" gives the users in the ACS group the System Admin role.

To create limited access roles for specific users, you must log in to WLSE and create a specific role with the necessary permissions and then enter the role name in TACACS+ using cmd-arg. For example, on the WLSE you can create the role called MyRole. Then, cmd-arg="MyRole" gives the users in that ACS group the role MyRole.

Step 9 Click User Setup on the left panel.

Step 10 Enter a username, for example user1, in the User field, then click Add/Edit to create a user, or you can edit a user that already exists.

Step 11 Enter a password and confirm the password. From the pulldown menu Group to which the user is assigned, select the group that you just created for WLSE. See Figure 1. (Optional: Add or edit Real Name and Description.)

Step 12 Click Submit to complete the ACS Configuration.

Setting Attributes

Step 13 Log in to WLSE as admin.

Step 14 Select Admin > Appliance > Security > Authentication Modules, then select TACACS+ as the module. Enter the shared secret key you entered when you defined the AAA client, then enter the ACS server IP address as the primary server. Click Apply.

Step 15 To verify that the setup was successful, log out of WLSE and log back in again as the ACS user you just created or modified.


ACS RADIUS Setup for WLSE

To set up ACS RADIUS for WLSE, you need to perform the following steps:

1. Add WLSE as a AAA client in ACS.

2. Set up the ACS group for WLSE.

3. Log in to WLSE and select the RADIUS authentication module.

Prerequisites

Before you can set up ACS RADIUS for WLSE, you need to make sure

RADIUS (Cisco/Aironet) appears in the list when you click Interface Configuration.

After you configure the network client as shown in the steps below, the cisco-av-pair must be enabled when you click Interface Configuration and then click the link for RADIUS (Cisco IOS/Pix 6.x).

Consult the CiscoSecure ACS documentation for steps on how to configure these settings if they are not already configured.

Procedure


Step 1 Log in to ACS with the admin user ID.

Step 2 Click Interface Configuration on the left panel. If RADIUS (Cisco IOS/PIX) appears in the list, click on it and go to step 7. If RADIUS (Cisco IOS/PIX) does not appear in the list, continue with step 3.

Step 3 Click Network Configuration on the left panel, then click Add Entry.

Step 4 In the Add AAA Client form, enter the following information to create the RADIUS (Cisco IOS/PIX) module:

AAA Client Hostname (for example, Radius Placeholder)

AAA Client IP Address (for example, 1.1.1.1)

Key (for example, placeholder.)

Authenticate Using RADIUS (Cisco Aironet)

Step 5 Click Submit.

Step 6 Click Interface Configuration on the left panel, then click RADIUS (Cisco IOS/PIX). The Interface Configuration window appears.

Step 7 Make sure the cisco-av-pair is checkbox is checked, then click Submit.

Step 8 Click Network Configuration on the left panel, then click Add Entry.

Step 9 In the Add AAA Client form, enter the following information:

AAA Client Hostname

AAA Client IP Address (Use your WLSE IP address.)

Key (You must either record or remember the key to configure WLSE.)

Authenticate Using RADIUS (Cisco Aironet)

Step 10 Click Submit.

Step 11 Click Group Setup. Select any group. Optional: Select a group ID and rename the group.

Step 12 Click Edit Settings. Under the Cisco IOS/Pix 6.x RADIUS Attributes section, enter the following parameters for the cisco-av-pair

WLSE:groups="System Admin" (case sensitive)

Step 13 Click Submit+Restart.


Note WLSE supports multiple user groups for a given user. In this case, the user will have combined privileges. The format to configure multiple group privileges for a given user is WLSE:groups="Role1","Role2","Role3".


The command WLSE:groups="System Admin" gives the users in the ACS group the System Admin role.

To create limited access roles for specific users, you must log in to WLSE and create a specific role with the necessary permissions and then enter the role name in RADIUS using WLSE:groups. For example, on the WLSE you can create the role called MyRole. Then, WLSE:groups="MyRole" gives the users in that ACS group the role MyRole.

Step 14 Click User Setup on the left panel.

Step 15 Enter a username, for example user1, in the User field, then click Add/Edit to create a user, or you can edit a user that already exists.

Step 16 Enter a password and confirm the password. From the pulldown menu Group to which the user is assigned, select the group that you just created for WLSE. See Figure 1. (Optional: Add or edit Real Name and Description.) Click Submit to complete the ACS Configuration.

Step 17 Log in to WLSE as admin.

Step 18 Select Admin> Appliance > Security > Authentication Modules, then select RADIUS as the module. Enter the shared secret key you entered when you defined the AAA client, then enter the ACS server IP address as the primary server. Click Apply.

Step 19 To verify that the setup was successful, log out of WLSE and log back in again as the ACS user you just created or modified.

http://www.cisco.com/techsupport/servicerequest

For S1 or S2 service requests or if you do not have Internet access, contact the Cisco TAC by telephone. (S1 or S2 service requests are those in which your production network is down or severely degraded.) Cisco engineers are assigned immediately to S1 and S2 service requests to help keep your business operations running smoothly.

To open a service request by telephone, use one of the following numbers:

Asia-Pacific: +61 2 8446 7411 (Australia: 1 800 805 227)

Definitions of Service Request Severity

To ensure that all service requests are reported in a standard format, Cisco has established severity definitions.

Severity 1 (S1)—Your network is "down," or there is a critical impact to your business operations. You and Cisco will commit all necessary resources around the clock to resolve the situation.

Severity 2 (S2)—Operation of an existing network is severely degraded, or significant aspects of your business operation are negatively affected by inadequate performance of Cisco products. You and Cisco will commit full-time resources during normal business hours to resolve the situation.

Severity 3 (S3)—Operational performance of your network is impaired, but most business operations remain functional. You and Cisco will commit resources during normal business hours to restore service to satisfactory levels.

Severity 4 (S4)—You require information or assistance with Cisco product capabilities, installation, or configuration. There is little or no effect on your business operations.
