Role

Constraints and Restrictions

Parent

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

  • The S6320EI, S6320SI, 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 connecting to an SVF system can be different models.

AS

  • When an AS is an S5700-10P-LI, S5700-10P-PWR-LI-AC or S2750EI and Layer 3 hardware forwarding for IPv4 packets has been enabled using the assign forward-mode ipv4-hardware command in the system view before the AS joins an SVF system, the AS cannot negotiate to join the SVF system if the AS directly connects to the parent and the management VLAN cannot be configured if the AS connects to the parent across a network.

    To solve these problems, start the AS in standalone mode and run the undo assign forward-mode command in the system view to disable Layer 3 hardware forwarding for IPv4 packets.

  • An AS can be a standalone device or a stack system of multiple devices.ach 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.

  • n 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.
  • In an SVF system, the last four ports of the S6720-32X-SI-32S-AC, S6720-32X-LI-32S-AC, S6720S-32X-LI-32S-AC, S6720-16X-LI-16S-AC, and S6720S-16X-LI-16S-AC are used as uplink ports. Therefore, a stack set up using the last four ports can join an SVF system as an AS.

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.

  • If downlink service ports of an AS are configured as member ports of an uplink fabric port, all the downlink ports of the AS cannot be configured as stack member ports.

  • 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.

  • ownlink 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.

CAPWAP

  • 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.
