Configuring FPGA fast forwarding
Support for this feature depends on the device model. For more information, see About the H3C Access Controllers Configuration Guides.
Overview
FPGA fast forwarding greatly improves an AC's forwarding efficiency by performing hardware forwarding with an FPGA card, which forwards wireless packets according to fast forwarding entries.
Wireless packets of the following categories are forwarded by software:
· Packets matching no fast forwarding entries.
· ARP and DHCP packets.
· Packets on interfaces to which QoS policies, CAR policies, or PQ lists are applied.
· Packets to which ACLs or user profiles are deployed.
· Other packets that cannot be forwarded by FPGA cards.
Enabling or disabling FPGA fast forwarding automatically clears Ten-GigabitEthernet interface statistics.
When FPGA fast forwarding is enabled, portal-forbidden rules (see Security Configuration Guide) do not take effect.
To configure portal-forbidden rules, use the undo fpga work-mode fast-forwarding command to disable FPGA fast forwarding first.
