Hence, this modem management feature is supported only with MICA modems.
The following example shows how to configure the network access server to recognize several RADIUS host entries with the same IP address.
This Click on the Next button. Because RADIUS accounting is facilitated through AAA, you must enter the The Cisco RADIUS implementation supports one vendor-specific option using the format recommended in the specification. The configuration of the RADIUS server is the same for all authentication types. a given feature in a given software release train. The following example shows the Prompt attribute set to No-Echo, which prevents the user’s responses from echoing: Note that because the username and password are not available, authorization is also bypassed. The ACCEPT or REJECT response is bundled with additional data that is used for EXEC or network authorization. (whether vendor-proprietary or IETF compliant), you must use the Use these resources to install and configure the software and to troubleshoot and resolve technical issues with Cisco products and technologies. The additional data included with the ACCEPT or REJECT packets consists of the following: On platforms with multiple interfaces (ports) per slot, the Cisco RADIUS implementation does not provide a unique NAS-Port attribute that permits distinguishing between the interfaces. Before you can perform subsequent authentication, you must set up a regular user profile in addition to a preauthentication profile. In the NPS console, double-click RADIUS Clients and Servers. AAA authorization lets you set parameters that restrict a user’s access to the network. shared secret text string used between the device and the vendor-proprietary Your software release If preauthentication passes, you can use vendor-proprietary RADIUS attribute 201 (Require-Auth) in the preauthentication profile to determine whether subsequent authentication is performed. If you insert an “*”, the AV pair “ip:addr-pool=first” becomes optional. To initiate the authorization process, you must also configure the Access the Server roles screen, select the Network Policy and Access Service option. The network access server monitors the RADIUS authorization and accounting functions defined by RADIUS attributes in each user profile: RADIUS authentication, authorization, and accounting configuration example are
The client device sends a request on the data link layer to an authenticator to gain access to the network. The Cisco Support and Documentation website provides online resources to download documentation, software, and tools.
Use the Cisco devices and send authentication requests to a central RADIUS server that (Optional) Tells the Cisco device or access server to query the RADIUS server for the static routes and IP pool definitions used throughout its domain. This table lists only the software release that introduced support for If you do not want this information to be sent, you can suppress it by using the Select Network Policy Server: Press Install to start the installation of the role: Press Close to exit from the wizard: Procced with the configuration of the Radius server selecting NAP, then right-click on the server name and press Network Policy Server: Right-click on NPS and select Register server in Active Directory: If subsequent authentication is required, the authorization attributes in the preauthentication profile are not applied. You can configure a RADIUS server on a WLC for Authentication under “Security -> RADIUS -> Authentication ” section as shown below. If you specified subsequent authentication in the preauthentication profile, you must also specify the authentication types to be used for subsequent authentication.
Add the VPN Server as a RADIUS Client. When the modem management string is received from the RADIUS server in the form of a VSA, the information is passed to the Cisco software and applied on a per-call basis.
Cisco software supports a subset of vendor-proprietary RADIUS attributes. Setting up the preauthentication profile in this manner prevents users from trying to log in to the NAS with the username of the DNIS number, CLID number, or call type and an obvious password. Enables the network access server to recognize and use vendor-specific attributes as defined by RADIUS IETF attribute 26. The lines in this sample RADIUS authentication and authorization configuration are defined as follows: RFC 2138 and RFC 2139 describe the basic functionality of RADIUS and the original set of IETF-standard AV pairs used to send AAA information. This server can be used for wired, wireless, and L2TP remote access authentication types. This entry should convert lowercase letters to uppercase, and also remove colons or periods from the MAC address. In one case, RADIUS has been used with Enigma’s security cards to validate users and grant access to network resources.
The following table The following example shows a configuration that specifies two-way authentication: RFC 2865 and RFC 2868 extend the IETF-defined set of AV pairs to include attributes specific to compulsory tunneling in VPNs by allowing the user to specify authentication names for the network access server and the RADIUS server. This information is sent when the user logs on and logs off, these are usually called accounting requests. For example, in a V.120 ISDN call, login or PPP authentication occurs on a virtual asynchronous interface “ttt”, but the call itself occurs on one of the channels of the ISDN interface. Identifies and the RADIUS server use this text string to encrypt passwords and exchange To configure the RADIUS preauthentication profile, use the Dialed Number Identification Service (DNIS) or Calling Line Identification (CLID) number as the username, and use the password defined in the The following example shows a RADIUS profile configuration with a callback number of 555-0101 and the service type set to outbound.
