Spanning Tree

Les switchs Alcatel proposent deux modes Spanning Tree :

  1×1 (AOS 6) – Per-Vlan (AOS 8) : une instance STP par VLAN
  Flat: une instance générale

Configuration flat

Port d’accès (Portfast)

Une fois le STP activé, les ports prennent plus longtemps à monter. Sur les ports d’accès (connectés au PC) il convient d’activer l’option Admin-Edge pour qu’ils montent plus vite.
