I would use always the same ports (e0e and e0f) used for peering for iscsi traffic but isn't clear for me how I can separate the traffic (iscsi_a, iscsi_b, nfs, cifs). Now I've configured differente subnets for peering iscsi_a and iscsi_b so there are a logical separation but tecnically isn't very correct and I would use a VLAN.
I can create a svm but I can't use a vlan for it; also the GUi (9.7) allow me choose only the IP but I don't have find where set the vlan.
I am kind at a loss where that GUI window is honestly... I honestly find this easier in the "Classic" gui or the CLI. the new GUI... is ehhh...
Back to your question. When you create a LIF you have to specify type. If it's "Data" you have to then specify the SVM. To "assign" a VLAN to a LIF (Network Interface) you just put it on the correct port. So if you want 192.168.100.101 to be on VLAN 100. add it to the a1a-100 port when creating the LIF.
