Configuring WLAN fast forwarding

About WLAN fast forwarding

WLAN fast forwarding uses both software and hardware to enhance forwarding performance. Software fast forwarding enables an AC to perform concurrent forwarding by using the multi-core CPU and the 5-tuple table. The AC learns the source IP, source port, destination IP, destination port, and protocol during forwarding and uses high-speed buffer technology to save the information in the 5-tuple table.

2.     Disable the hardware forwarding function.

wlan fast-forwarding hardware disable

By default, the hardware forwarding function is enabled.

Enabling fast broadcast forwarding

About this task

In centralized forwarding, the AC uses its CPU to process received wireless broadcast packets. This requires a lot of resources if a large number of devices and clients operate in the WLAN and might affect wireless services.

Fast broadcast forwarding enables the AC to use the FPGA chip, instead of the CPU, to process wireless broadcast packets. This reduces the workload of the CPU, enhances AC availability, and improves user experience.

Restrictions and guidelines

For the feature to take effect, make sure WLAN fast forwarding is enabled before you enable fast broadcast forwarding.

Only devices that support hardware forwarding support this feature.

Procedure

1.     Enter system view.

system-view

2.     Enable fast broadcast forwarding.

wlan fast-forwarding broadcast-enhance enable

By default, fast broadcast forwarding is disabled.
