Roles in an SVF System

Roles in an SVF System

Figure 10-2  SVF-related concepts

In Figure 10-2, an SVF system consists of the parent and client, which are connected through fabric ports. For the roles in an SVF system, see Table 10-1.

Table 10-1  Roles in an SVF system




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


Client refers to all access devices, including wired access devices (ASs) and wireless access devices (AP). ASs are classified into level-1 and level-2 ASs.

  • 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.
  • 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.


A fabric port is a logical port that connects the parent and a level-1 AS or connects a level-1 AS and a level-2 AS. One or more member ports can be added to a fabric port, and one fabric port can connect to only one AS. Ports 1 through 6 in the preceding figure.

  • Service ports on fixed switches include uplink and downlink ports. For details about uplink and downlink ports, see the "Naming Conventions" section in the Hardware Description - Chassis.
  • Only uplink ports can be used as member ports of a fabric port. To use downlink ports as member ports of a fabric port, run the uni-mng up-direction fabric-port member interface interface-type interface-number [ to interface-number ] command to set these downlink ports as uplink ports.
