1. Was ist SNMP?<\/strong><\/h2>\n\n\n\n
    \n
  • Protokoll f\u00fcr Netzwerkmanagement<\/li>\n\n\n\n
  • Versionen:\n
      \n
    • SNMP v1<\/strong><\/li>\n\n\n\n
    • SNMP v2c<\/strong><\/li>\n\n\n\n
    • SNMP v3<\/strong> (mit Sicherheitsfunktionen)<\/li>\n<\/ul>\n<\/li>\n\n\n\n
    • Modell:\n
        \n
      • Manager<\/strong> (zentrale Instanz)<\/li>\n\n\n\n
      • Agent<\/strong> (l\u00e4uft auf Ger\u00e4ten und liefert Daten)<\/li>\n\n\n\n
      • Kommunikation \u00fcber Polling (Abfragen)<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n\n\n\n

        2. Wichtige Begriffe<\/strong><\/h2>\n\n\n\n
          \n
        • MIB (Management Information Base)<\/strong>
          Struktur\/\u201eDatenbank\u201c mit allen abrufbaren Informationen<\/li>\n\n\n\n
        • OID (Object Identifier)<\/strong>
          Eindeutige Kennung f\u00fcr jeden Datenpunkt (wie eine Adresse)<\/li>\n\n\n\n

              \n
            • Manager sendet Anfragen:
              Get<\/code>, Set<\/code>, GetNext<\/code><\/li>\n\n\n\n
            • Agent antwortet mit Daten<\/li>\n\n\n\n
            • Agent kann Traps (Alarme)<\/strong> senden<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n\n\n\n

              4. SNMP Message-Typen<\/strong><\/h2>\n\n\n\n
