Title: How do I apply Ruijie virtual AP solution?
1. Summarize
Virtualization AP is a method of virtualizing a physical AP into multiple logical APs. Each logical AP is called a virtual AP. Each virtual AP is independently managed and controlled by an independent AC device. Through virtual AP technology and its networking scheme, the management, control, and data of different wireless networks on the same physical AP can be comprehensively isolated, achieving high security characteristics.
2.Explanation of nouns
(1) Main AP: After a physical AP is enabled, a logical AP is created to work by default. This logical AP occupies all AP resources. The logical AP created by default is the active AP.
(2) Virtual AP: A virtual AP is a logical AP created after the active AP and AC establish a tunnel and receive the configuration for creating a virtual AP from the AC.
(3) Master-control AC: The AC connected to the active AP is called the Master-control AC. After a physical AP is connected to an AC, an administrator can create a virtual AP on this AC, configure the management AC for the virtual AP, and allocate resources to the virtual AP. This AC is the Master-control AC for this physical AP and all virtual AP on the physical AP.
(4) Sub-control AC: The AC that establishes a tunnel with the virtual AP is called the Sub-control AC of the physical AP.
3.Networking mode
Two networking modes are available based on the usage of the AP upper link: single AP upper link and double AP upper link.
(1) Single uplink: The Master-control AC and branch Sub-control AC use the same uplink port for communication (the aggregation port must be the same uplink port).
(2) Dual-uplink: The Master-control AC and sub-control AC use different upper interfaces for communication (that is, different upper links).


<span style=""">4.Technical scheme
</span>
(1) After powering on the AP, establish a CAPWAP tunnel with the Master-control AC.
a. Unicast can discover only the Master-control AC (acip, cluster, and DHCP discovery).
b. If the AP and the AC are on a Layer-2 network, the AC shields the Layer-2 discovery of the AP
(Discovery of broadcast, multicast, and DNS).
(2) The Master-control AC delivers the virtual AP template configuration, and the AP creates a virtual AP.
(3) Confirm the IP address used by the virtual AP based on the above interface configuration:
a. If the upper interface is configured as the upper interface of the primary AP, the virtual AP uses the IP address of the primary AP.
b. If the configuration of the upper interface is different from that of the active AP, the IP address is obtained from the DHCP configured on the upper interface.
(4) After the virtual AP obtains the IP address, it establishes a CAPWAP tunnel with the IP address of the Sub-control AC configured in the virtual AP template.
The AP, the Master-control AC, and the sub-AC have established their own CAPWAP tunnels, allowing the Master-control AC and the sub-AC to independently manage the AP.
5. Configuration instruction
(1) If the virtual AP and the Sub-controlled AC are in a two-layer network, the Sub-control AC configuration rejects the AP's two-layer discovery, and is configured in the AC configuration mode:
a. Capwap discovery type unknown forbidden
b. Capwap discovery type dns forbidden
(2) The Master-control AC configures the virtual APtemplate in the global configuration mode:
Virtual-ap xxx #Create an virtual AP template (xxxparameter is a name in string format)
Ac-ip x.x.x #Configure the IP address of theSub-control AC of the virtual AP template
Wlan capacity xx #Configure the number of WLANconfigurations supported by the virtual AP created by the virtual AP template
Sta capacity xx #Configure the number of STAaccesses supported by the virtual AP created by the virtual AP template
Link-interface xx #Configure the uplink used by the virtual AP created by the virtual AP template.
(3) Application of virtual AP templates. If an AP wants to create several virtual APs, it needs to apply several virtual AP templates. You can use the AP configuration mode "AP group configuration mode and configuration in all AP configuration modes (if the AP configuration mode has applications, issue the configuration in AP configuration mode; if the AP configuration mode has no applications, but the AP group configuration mode has applications, issue the configuration in AP group mode; if the AP group configuration mode has no applications, but all AP configuration modes have applications, issue the configuration in all AP modes), taking the AP configuration mode as an example:
(config-ap)#virtual-ap VAP_ 1 id 1 #Applicationcalled VAP_ virtual AP template for 1 has a virtual AP number of 1
(config-ap)#virtual-ap VAP_ 2 id 2 #Applicationcalled VAP_ The virtual AP template for 2 has a virtual AP number of 2
(config-ap)#virtual-ap VAP_ 3 id 3 #Applicationcalled VAP_ The virtual AP template for 3 has a virtual AP number of 3
6. Troubleshooting common faults
(1)Check whether the AP supports virtual AP
(2)Check whether the AP is in hot spare and tieringAC
(3)Check whether the virtual AP templateconfiguration is delivered to the AP
(4)Check whether the link-interface configurationis correct
