Cette tâche montre le flux de trafic dans la configuration RSTP sur SEFOS exécuté sur les commutateurs cibles. Cette tâche vérifie si une boucle est présente dans la topologie, si elle est détectée et si le trafic est bloqué pour le port de remplacement.
Voir la section Switching Feature Topology pour connaître la topologie de cette tâche.
Voir la section Configure Initial Settings.
Voir la section Configure VLAN Forwarding.

Le trafic doit être acheminé via le port xl-ethernet 0/2 sur SEFOS-1. Si RSTP fonctionne, le statut du port sera modifié.
