Chapter 4 Setting Up and Managing Network Configuration
AAA Server Configuration
Step 8 In the AAA Server Type list, select the protocol the remote AAA server is
configured to use:
• RADIUS—Select this option if the remote AAA server is configured using
any type of RADIUS protocol.
• TACACS+—Select this option if the remote AAA server is configured using
the TACACS+ protocol.
• Cisco Secure ACS for Windows 2000/NT—Select this option if the remote
AAA server is another Cisco Secure ACS. This enables you to configure
features that are only available with other Cisco Secure ACS servers, such as
CiscoSecure user database replication and remote logging.
Note The remote Cisco Secure ACS must be using Version 2.1 or later.
Step 9 The Traffic Type list defines the direction in which traffic to and from the remote
AAA server is allowed to flow from this local Cisco Secure ACS. From the Traffic
Type list, select one of the following options:
• Inbound—The selected AAA server accepts requests that have been
forwarded to it and does not forward the request to another AAA server.
Select this option if you do not want to allow any authentication requests to
be forwarded from the remote AAA server.
• Outbound—The selected AAA server sends out authentication requests but
does not receive them. If a Proxy Distribution Table entry is configured to
proxy authentication requests to a AAA server that is configured for
Outbound, the authentication request is not sent.
• Inbound/Outbound—The specified AAA server forwards and accepts
authentication requests. This allows the selected server to handle
authentication requests in any manner defined in the distribution tables.
