Hi all,

I added vlan and found network disconnection in Data Ontap 7-mode.

The messages are below.

How do I add a vlan without links down?

Is there any special command?

Please let me know.

Thanks.

Adding a vlan does not bring interfaces down. It looks liek you are using an unspported SFP+ module
