O artigo aplica-se a: 

To isolate broadcast domains and for security consideration, Access Points may be deployed in different 802.1Q VLANs. In this application scenario, TP-Link AC controller must be capable to manage CAPs in different VLANs like CAPs in VLAN2 and VLAN3 shown as below. This document will introduce how to use AC500 to manage CAPs (CAP300, CAP1750) in different VLANs.

In this Instance, We have CAP300 in VLAN2 and CAP1750 in VLAN3. VLAN2 and VLAN3 should be isolated with each other, but both can go to Internet normally through gateway router.

 

Step1. 802.1Q VLAN Configurations on L2 Switch

Port 1 which is connected to AC500 should be set as Access Type (PVID=1)

Port 2 should be set as General Type (VLAN1 & VLAN2 allowed, egress rule Untag, PVID=1)

Port 3 should be set as General Type (VLAN1 & VLAN3 allowed, egress rule Untag, PVID=1)

Port 4 which is connected to gateway Router should be set as General Type (VLAN1 & VLAN2 & VLAN3 allowed, egress rule Untag, PVID=1).

 

Step2. Wireless Configurations on AC controller AC500

Check if CAP300 in vlan2 and CAP1750 in vlan3 can be discovered by AC500. Here we can see CAP300 in vlan2 and CAP1750 in vlan3 can be both managed by AC500.

Create 2 SSIDs, and name them as “VLAN2” and “VLAN3”.

Click “Radio Binding”. Bind SSID “VLAN2” to CAP300 in VLAN2 and bind SSID “VLAN3” to CAP1750 in VLAN3.

 

Step3. Check CAP Status and Client Internet Access

After all configurations, you can check if your wireless client device can go to Internet normally through wireless network VLAN2 (CAP300) and wireless network VLAN3 (CAP1750), and check if CAPs in different VLANs can be managed normally by AC controller.
