Dieses Dokument beschreibt eine Beispielkonfiguration für einen Cisco 6400 Universal Access Concentrator (UAC), der MUX-PPP und Subnetwork Access Protocol (SNAP) unterstützt und eine atm ilmi-pvc-discovery-Subschnittstelle verwendet.
Für dieses Dokument bestehen keine speziellen Anforderungen.
Dieses Dokument ist nicht auf bestimmte Software- und Hardwareversionen beschränkt.
Die Informationen in diesem Dokument wurden von den Geräten in einer bestimmten Laborumgebung erstellt. Alle in diesem Dokument verwendeten Geräte haben mit einer leeren (Standard-)Konfiguration begonnen. Wenn Ihr Netzwerk in Betrieb ist, stellen Sie sicher, dass Sie die potenziellen Auswirkungen eines Befehls verstehen.
Weitere Informationen zu Dokumentkonventionen finden Sie in den Cisco Technical Tips Conventions.
In diesem Abschnitt erhalten Sie Informationen zum Konfigurieren der in diesem Dokument beschriebenen Funktionen.
Hinweis: Um weitere Informationen zu den in diesem Dokument verwendeten Befehlen zu erhalten, verwenden Sie das Command Lookup Tool (nur registrierte Kunden).
