Creating a VN

Creating a VN

Context

After a fabric is created, you can select network resources in the fabric to create VN instances. Different VNs represent services of different users, and thereby services of multiple users can be isolated from each other through VNs.

In the centralized gateway solution, if the recommended tunnel forwarding mode is used on the WLAN and the border node functions as the native WAC and wireless subnet gateway, wireless user traffic needs to be forwarded to the border node through the CAPWAP tunnel. The border node decapsulates CAPWAP packets and then forwards the decapsulated packets. If wireless traffic needs to be forwarded out by entering a particular VN, you can bind the gateway interface of the corresponding wireless subnet to a VN instance. The gateway interface can be a VLANIF or VBDIF interface. The binding process is performed on the border node using commands.

Configuration Tasks

Description

Operation Procedure

Creating a VN
  1. (Optional) Select an external network, which is usually needed for communication with the VN.
  2. (Optional) Select network service resources, which are usually needed for communication with the VN.
  3. Configure a user gateway, which can be manually specified or automatically allocated.
  4. Configure wired access: Select the access ports configured during access management configuration for the fabric, and add the ports to the service VLAN configured on the user gateway.
  5. Configure wireless access: Select the WAC that connects to the wireless user subnet. Then the service VLAN configured on the user gateway will be delivered to the WAC. The WAC needs to be the authentication control point configured during access management configuration for the fabric, which is applicable to the distributed gateway scenario where the authentication control points for wired and wireless users are unified.
