Data forwarding mode
Data forwarding mode: - Centralized forwarding (also called tunnel forwarding): APs set up control tunnels and data tunnels with an AC. Control data between the AP and AC and service data from WLAN users are encapsulated in the control tunnel and data tunnel, respectively. After the service data reaches the APs, it must be sent to the AC through the data tunnel first and then be forwarded at L2 and L3. - Direct forwarding (also called local forwarding): APs only set up control tunnels with an AC. After the service data reaches the APs, it directly enters the wired network through the switch that connects to the APs and then be forwarded at L2 and L3. In summary, tunnel forwarding facilitates centralized management and control, and service data must be forwarded through an AC, reducing packet forwarding efficiency and burdening the AC. For direct forwarding, packet forwarding efficiency is high. You can select either of the forwarding mode as required. AC deployment - Bypass mode ACs are directly connected to aggregation switches or core switches in bypass mode. If two ACs provide 1+1 backup, they connect to the aggregation switch or core switch. - Establish an independent AC management area that connects to the core switch in bypass mode. In actual networking, an aggregation switch is connected to the core switch in bypass mode, and all the ACs are connected to the aggregation switch. Verify the forwarding mode by checking that an AC serves as the gateway or running the display forward-type service xx command.

What are the differences in AP-side switch interface configuration and intermediate switch configuration in direct and tunnel forwarding modes

Can broadcast and multicast packets be simultaneously suppressed after traffic suppression is enabled on an interface of an S series switch
Traffic suppression can be configured for both broadcast and multicast packets on an interface of an S series switch. Traffic suppression on an interface is implemented for one type of packets as follows: After broadcast traffic suppression is enabled on an interface, only broadcast packets are suppressed. After unknown multicast traffic suppression is enabled on an interface, only unknown multicast packets are suppressed. After unknown unicast suppression is enabled on an interface, only unknown unicast packets are suppressed.
