Prerequisites

Requirements

There are no specific requirements for this document.

Components Used

The information in this document is based on these software and hardware versions:

  • Access Control Server (ACS) version 2.6.4 and later

The information in this document was created from the devices in a specific lab environment. All of the devices used in this document started with a cleared (default) configuration. If your network is live, make sure that you understand the potential impact of any command.

Conventions

Background Information

There is no option to configure TACACS+ or RADIUS accounting or command authorization for EXEC sessions in the GUI. These options can be configured in the CLI, but are not recommended. If you configure these options, they can severely bog down the AP and ACS with accounting or authorization requests (each element of each page must be accounted or authorized for).

ACS Configuration

Interface Configuration

Complete these steps to configure the interface:

  1. In TACACS+ (Cisco IOS), select the group box for the first undefined new service field.

  2. In the Service field, enter Aironet.

  3. In the Protocol field, enter Shell.

  4. In Advanced Configuration Options, choose Advanced TACACS+ Features > Display a window for each service selected.

  5. Click Submit.

User Configuration

Complete these steps to configure the user:

  1. In Advanced TACACS+ Settings, select Shell (exec).

  2. Select Privilege level.

  3. In the field, enter 15.

  4. Click Submit.

Group Configuration

Complete these steps to configure the group:

  1. Choose TACACS+.

  2. Choose Aironet Shell > Custom attributes.

  3. In the Custom Attributes field, enter aironet:admin-capability=write+ident+firmware+admin+snmp.

  4. Click Submit.

  5. Restart.

Network Configuration

Complete these steps to configure the network:

  1. Create NAS for the AP using TACACS+ as the protocol.

  2. The key is the shared secret from the AP.

  3. Click Submit.

  4. Restart.

Note: If you are using a token server with a one time password, you need to configure token caching in order to avoid being continually prompted for level 1 and level 15 passwords. Complete these steps to configure token caching:

  1. Enter group configuration for the group to which your admin users belong.

  2. Choose Token Card Settings.

  3. Select Duration.

  4. Choose a duration that balances your needs for security and convenience.

If your typical admin session lasts five minutes or less, then a duration value of five minutes is best. If your session runs longer than five minutes, you are prompted again for your password at five minute intervals. Note that the Session option does not work without accounting enabled. Also, note that token caching is in effect for all users in the group, and for all of the group's sessions with all devices (not just EXEC sessions to the AP).
