The traffic-optimize bcmc deny all command forbids an air interface to forward downstream broadcast or multicast packets.
The undo traffic-optimize bcmc deny all command cancels the configuration of forbidding an air interface to forward downstream broadcast or multicast packets.
By default, an air interface is allowed to forward downstream broadcast or multicast packets.
On an IP network, the ARP, ND, and DHCP protocols are the basic network protocols and serve as the basis for packet forwarding on the entire network. Broadcast or multicast packets of protocols other than the ARP, ND, and DHCP protocols are optional on the IP network. When no services rely on transmission of these broadcast or multicast packets on the network, you can run the command to forbid an air interface to forward these broadcast or multicast packets to improve the air interface performance.
PrecautionsBefore using the traffic-optimize bcmc deny all command to forbid an AP to forward downstream broadcast or multicast packets, run the undo learn-client-address { ipv4 | ipv6 } disable command to enable STA address learning and the traffic-optimize bcmc unicast-send { arp | nd | dhcp } * command to configure the function of converting broadcast or multicast packets to unicast packets on an air interface. Otherwise, the ARP, ND, and DHCP packets may fail to be forwarded.
