traffic-optimize bcmc deny all

traffic-optimize bcmc deny all

Function

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.

Format

traffic-optimize bcmc deny all

undo traffic-optimize bcmc deny all

Parameters

None

Views

Traffic profile view

Default Level

2: Configuration level

Usage Guidelines

Usage Scenario

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.

Precautions

Before 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 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.

Example

# Forbid an air interface to forward downstream broadcast or multicast packets in the traffic profile p1.

<Huawei> system-view
[Huawei] wlan
[Huawei-wlan-view] traffic-profile name p1
[Huawei-wlan-traffic-prof-p1] traffic-optimize bcmc deny all
