Function Overview

This topic describes the application scenario and related concepts of the Super Virtual Fabric (SVF) configuration management.

Application Scenario

The access layer of a traditional campus network has the following characteristics:

  • A large number of access devices are distributed sparsely.
  • Services are simple and configurations on different access devices are similar.
  • The trend towards wired and wireless convergence grows.

Management and configuration of access devices are time-consuming due to the preceding characteristics. Super Virtual Fabric (SVF) technology effectively simplifies management and configuration of access devices.

SVF technology virtualizes aggregation and access devices into one logical device and allows aggregation devices to manage and configure access devices.

Compared with the traditional access layer networking, the SVF networking has the following advantages:

  • Unified device management: SVF virtualizes aggregation and access devices into one logical device and allows aggregation devices to manage and configure access devices.
  • Unified configuration: SVF implements batch configuration of access devices based on profiles, removing the need to configure access devices one by one.
  • Unified user management: SVF manages wired and wireless access users in a unified manner.


The SVF networking is as follows:

  • Parent

    A parent is an aggregation device that manages and configures an SVF system.

  • Client

    Client refers to all access devices, including wired access devices (ASs) and wireless access devices (AP):

    • Access switch (AS)

      An AS is an access switch that connects to wired terminals.

      • Level-1 AS: is directly connected to the parent or is connected to the parent across a Layer 2 network.
      • Level-2 AS: is directly connected to a level-1 AS. When a level-1 AS is connected to the parent across a Layer 2 network, level-2 ASs are not supported.
    • Access point (AP)

      An AP is a Wireless Local Area Network (WLAN) access point that connects to wireless terminals. When APs access an SVF system, the parent functions as an AC to control and manage all the APs in the SVF system.

  • Fabric-port

    A fabric port is a logical port that connects the parent and a level-1 AS and connects a level-1 AS and a level-2 AS. One or more member ports can be added to a fabric port. Member ports in a fabric port can only be connected to the same AS.
