Roles in an SVF System

Roles in an SVF System

Figure 9-2  SVF-related concepts

In Figure 9-2, an SVF system consists of the parent and client, which are connected through fabric ports. For the roles in an SVF system, see Table 9-1.

Table 9-1  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.
