Bonjour, merci d'avance de votre aide.
j'ai 4 interfaces réseaux sur un serveur qui lui même est connecté à un SAN en iscsi.
eth0 et eth1 en bond mode 0 avec bond_miimon 100
eth2 et eth3 en bond mode 0 avec bond_miimon 100
Ces 4 interfaces sont reliés à un un switch dell 5548. Dessus il y a 2 LAG configuré, 1 pour chaque bonding :
# LAG LAG Type LAG Status LAG Speed Auto Negotiation Flow Control
1 1 eth1000M Up 1000M Enabled On
2 2 eth1000M Up 1000M Enabled On
Exemple de config pour un port :
#=5 Port=gi1/0/5 State=Disabled Role=N/A mode=RSTP FastLink=disabled
Point to point admin=auto Point to Point Operational Status=N/A
ça marchait plutôt bien jusqu'à présent sauf que maintenant, j'ai assez souvent des soucis. Voilà ce que je vois dans les logs. En général ça peut être 2 fois par jours et puis tranquille pendant 3 jours par exemple. LE soucis c'est qu'il perd la connexion au SAN et me sort des des I/O errors. LEs ports concernés sont gi1/0/5 gi1/0/14 gi3/0/5 gi3/0/14
