Hi Bruno,

Based on your question it seems that you are using management and interface/ve IP addresses on the same subnet. For best practice, we suggest that your data and control plane traffic are separated. We have enabled the feature on ACOS that if the same subnet is applied on the data and control plane, this will result to an error in the cli or gui. So my suggestion is to use 10.1.8.10 for control plane/management interface and use another subnet for data. I hope this helps.

Regards,

Genard
