Restrictions on SVF Roles

Restrictions on SVF Roles

Table 4-8  Constraints and restrictions on SVF roles


Constraints and Restrictions


  • The parent can be a standalone device, a stack system, or a cluster switch system (CSS).

  • The S5730HI, S6720SI, S6720S-SI, S6720EI or S6720S-EI can function as the parent or AS. By default, S5730HI works in parent mode, and other switches work in AS mode. To change the switch working mode, run the as-mode disable command. When the S5730HI work in AS mode, the WLAN function becomes unavailable.
  • ASs or APs connecting to an SVF system can be different models.


  • An AS can be a standalone device or a stack system of multiple devices. Each AS can be a stack of up to five member devices that are the same model and provide the same number or different numbers of ports.

  • An AS can be a stack of the same device series but different device models. If an AS is a stack, you can run the slot command to modify the preconfigured device type. To determine which different device models can set up a stack, see "Stacking Support and Version Requirements" in Stack Configuration in the Configuration Guide - Device Management.
  • Stack member switches connected using downlink service ports cannot join an SVF system as ASs.


  • If an AP has been connected to the parent before the SVF function is enabled, the parent cannot collect topology information about the AP after the uni-mnguni-mng command is used to enable the SVF function. You need to run the commit { all | ap ap-id } command in the WLAN view to commit the AP configuration. Subsequently, the parent can collect topology information about the AP.

  • From V200R011C10, WLAN configurations are automatically delivered, without the need of running the commit all command.
  • If APs need to connect to an SVF system with an S12700/S9700/S7700 functioning as the parent, X series cards must be installed on the parent to manage APs.

Fabric port

  • Service ports of fixed switches are classified into uplink and downlink service ports. For details about uplink and downlink service ports, see the "Naming Conventions" section in the Hardware Description - Chassis.

  • When GE optical interfaces are connected to XGE optical interfaces to connect level-1 ASs to the parent or connect level-2 ASs to level-1 ASs, these interfaces must use GE instead of XGE optical modules.

  • When an AS connects to APs, all member ports of the Eth-Trunk bound to the fabric port that connects the parent to the AS must be ports on X series cards or ports on non-X series cards. Otherwise, APs cannot go online.

  • Downlink service ports of an AS can also be connected to the upstream parent or AS after you configure them as member ports of an upstream fabric port using the uni-mng up-direction fabric-port member interface interface-type interface-number [ to interface-number ] command.
  • A downlink service port of an AS cannot be configured as a member port of upstream and downstream fabric ports simultaneously. If this configuration is performed, the AS will be unable to go online after a reboot. If the reset slot command is executed in the slot of the AS, the AS will reset repeatedly.
  • Ports on an AS subcard and uplink service port on an AS can only be used as member ports of a fabric port or as stack member ports and cannot be used as service ports.
  • AS uplink ports can be used to connect to the parent or level-1 AS or set up a stack and be configured as downlink fabric ports to connect to other ASs.


  • Configured CAPWAP tunnel parameters apply to the SVF system. To ensure that the CAPWAP tunnel of the SVF system works normally, you are advised to retain the default CAPWAP tunnel parameters.
