Was ist VTP

  • Synchronistation der Vlans über Switches hinweg.
  • Verwaltungsaufwand wird reduziert
  • Kann zu Fehlern führen
  • Austausch von
    • Vlan ID
    • Vlan Name
  • Kein Austausch von
    • Vlan Inetrface Zuordnungen
  • VTP MODI
    • VTP Server
    • VTP Client
    • VTP Transparent
