(Optional) Setting a Forwarding Model for the SVF System

(Optional) Setting a Forwarding Model for the SVF System

Context

Leaf switches in an SVF system support the following forwarding models:
  • Centralized forwarding: Leaf switches send all traffic to the parent switch for forwarding.

  • Distributed forwarding: Leaf switches first look up local forwarding entries for traffic forwarding. If they fail to find the matching entries, they discard Layer 3 traffic and broadcast Layer 2 traffic in the SVF system.

  • Hybrid forwarding: Leaf switches learn only local ARP and MAC address entries. (Only service ports learn entries, while ports connecting to the parent switch do not learn entries). They send broadcast and multicast traffic to the parent switch for forwarding and forward unicast traffic based on local ARP and MAC address entries preferentially. If they fail to find the matching entries, they send unicast traffic to the parent switch for forwarding.

    CE6810LI switches without Layer 3 forwarding capability learn only MAC address entries.

NOTE:
  • The forwarding model configured for an SVF system takes effect only after you restart the SVF system.

  • CE6810LI switches do not support the distributed forwarding model when they function as leaf switches.

Procedure

  1. Run the system-view command to enter the system view.
  2. Run the stack command to enter the stack management view.
  3. Run the stack forwarding-model { centralized | distributed | hybrid } command to set a forwarding model for the SVF system.

    By default, the forwarding model of leaf switches in an SVF system depends on the model of the parent switch:
    • When the parent switch is a CE6850EI/CE6810EI/CE7850EI, the CE6810LI leaf switches use the hybrid forwarding model and the leaf switches of other models use the distributed forwarding model.

    • When the parent switch is another model, the leaf switches use the hybrid forwarding model.

    To enable low-specification leaf switches to have the feature capabilities and specifications of parent switches, use the hybrid forwarding mode.

  4. Run the commit command to commit the configuration.
