First of all, you need to identify your own requirement, you want to have VLAN gateway on switch? or NGAF?

Scenario 1
If you want to have a VLAN gateway on your switch, you must first create a list of VLAN databases and network segmentation, and those VLANs must point to the NGAF's default gateway, which must create a Layer 3 interface and an IP address on the NGAF itself and the switch, and the NGAF must have a return route to your switch.

Scenario 2
VLAN gateway on NGAF, in the same step, list all your VLAN and IP Segmentation, and your NGAF acting as gateway for those VLAN, which means your user/server point to NGAF IP as gateway, and the switch only needs to allow all trunk the VLAN you configured. In this case, your switch operates in Layer 2 mode, with no routing configuration or Layer 3. This is the simplest way to set up a network, but keep in mind that you must allow inter-vlan communication in the firewall to ensure that all traffic is reachable.

So conclusion, you need to finalize your VLAN, how many VLAn you want? what are IP segments you want? which gateway you want? either NGAF or switch? at least you need to have your own design document and baseline to start configure.

As the following figure shows, the switch connects to two different groups. It is required that the computers in the two groups cannot communicate with each other, but both of them can access the internet via the router.
Configuration Scheme
To meet the above requirements, you can configure 802.1Q VLAN on the switch.

(By default, all ports belong to VLAN 1.)</span></p>

There is two tipe of configuration you can use, TAG/TRUNK port  or UNTAG/Access port from switch to NGAF.
If your TP-LINK was L2 Switch my suggestion is using TAG/TRUNK model and If the TP-LINK is L3 Switch then you can use UNTAG/Access model.

1. Configure VLAN on the core switch
2.Configure the trunk ports on the core switch

What kind of setup that you need for? do you any topology that you can share with us?

the basic configuration is config Vlan on core switch and setup the trunk port from the core switch to sangfor, then set the allowed vlan that you need

Confirure the vlan on the switch and assignthe same VLAN to sangofr port.

You need to identify which Vlan and the port as Access or Trunk

All configuration will be done on Core Switch because VLAN concept is related to switches not to FW. For communication between these VLANs, we need either Router or Layer 3 switch.

1. Configure the VLAN. All the switches that carry the VLAN must be configured for that VLAN. ...
2. Set up access control lists. ACLs, which regulate the access granted to each user connected to a network, also apply to VLANs. ...
3. Apply command-line interfaces.
4. Consider management packages.
