In diesem Dokument wird veranschaulicht, wie Zugriffslisten auf Wählschnittstellen mit einem RADIUS-Server angewendet werden. Es gibt zwei Möglichkeiten:
Definieren Sie die Liste mit nummerierten Zugriffsrechten auf dem Router, und verweisen Sie dann auf die Liste mit nummerierten Zugriffsrechten auf dem RADIUS-Server. Die meisten Cisco IOS® Software-Versionen unterstützen dies. Definieren Sie z. B. die nummerierte Zugriffsliste auf dem Router, und verweisen Sie auf diese auf dem Server.
Definieren Sie die gesamte Zugriffsliste auf dem Server. Für diese benutzerspezifische Methode ist die Cisco IOS Software Release 11.3 oder höher erforderlich. Definieren Sie z. B. die Zugriffsliste auf dem RADIUS-Server (und nicht auf dem NAS). Wenn der Anruf verbunden wird, authentifiziert das NAS-Gerät den Anruf mit dem RADIUS-Server. Zusammen mit allen Authentifizierungsinformationen gibt der Server die Zugriffsliste an das NAS-Gerät zurück, das dann auf die Wählschnittstelle angewendet wird.
Hinweis: Für ISDN müssen Sie die benutzerspezifische Methode verwenden und virtuelle Profile auf dem Router konfigurieren. Diese werden in der Konfiguration von virtuellen Profilen für die Cisco IOS-Softwareversion 11.3 beschrieben.
Für dieses Dokument bestehen keine speziellen Anforderungen.
Die Informationen in diesem Dokument basieren auf diesen Software- und Hardwareversionen.
Cisco IOS Software Release 11.1 oder höher (Zugriffslisten auf dem Router definieren)
Cisco IOS Software Release 11.3 oder höher (Zugriffslisten auf dem Server definieren)
Cisco Secure ACS UNIX oder Cisco Secure ACS für Windows 2.x oder Livingston RADIUS oder Merit RADIUS
Die in diesem Dokument enthaltenen Informationen wurden aus Geräten in einer bestimmten Laborumgebung erstellt. Alle in diesem Dokument verwendeten Geräte haben mit einer leeren (Standard-)Konfiguration begonnen. Wenn Sie in einem Live-Netzwerk arbeiten, stellen Sie sicher, dass Sie die potenziellen Auswirkungen eines Befehls verstehen, bevor Sie es verwenden.

Dieses Verfahren umfasst die Konfiguration der Zugriffsliste selbst auf dem Router. Der RADIUS-Server wird mit der angewendeten Zugriffslistennummer konfiguriert. Wenn der Anruf authentifiziert wird, gibt der RADIUS-Server die Nummer der Zugriffsliste an das NAS-Gerät zurück, das dann die entsprechende Zugriffsliste anwendet.
Führen Sie die folgenden Schritte aus:
Geben Sie in den Benutzereinstellungen den Namen und das Kennwort ein.
Aktivieren Sie in den Gruppeneinstellungen Folgendes:
Attribut 6 - Framed
Attribut 7 - PPP
Attribut 11 - Filter-ID. Geben Sie im Bereich unten 101.in ein.
Hinweis: Attribut 11 gibt an, dass die Zugriffsliste 101 angewendet wird. Stellen Sie sicher, dass die Zugriffsliste 101 auf dem Router konfiguriert ist.

Hinweis: Attribut 11 gibt an, dass die Zugriffsliste 101 angewendet wird. Stellen Sie sicher, dass die Zugriffsliste 101 auf dem Router konfiguriert ist.
chaprtr Password = chaprtr User-Service-Type = Framed-User, Framed-Protocol = PPP, Framed-Filter-Id = 101.in
Hinweis: Diese Eigenschaft gibt an, dass die Zugriffsliste 101 angewendet wird. Stellen Sie sicher, dass die Zugriffsliste 101 auf dem Router konfiguriert ist.

Hinweis: Routenanweisungen müssen nicht vom Server an den Router weitergeleitet werden. Der Wählbenutzer nimmt normalerweise die Routen vom Router ab. Das Vorhandensein der Routenanweisungen auf dem Router hängt davon ab, ob die Routen vom Server heruntergefahren oder vom Router übernommen werden sollen. In diesem Beispiel werden jedoch die Zugriffsliste und die Routenanweisungen übergeben.

In dieser Beispielkonfiguration dient das Übergeben der Routen vom Server nur zur Veranschaulichung.
