traffic-optimize broadcast-suppression disable (AP system profile view)

Function

The traffic-optimize broadcast-suppression disable command disables rate limit for broadcast and multicast packets on an AP.

The undo traffic-optimize broadcast-suppression disable command enables rate limit for broadcast and multicast packets on an AP.

By default, rate limit for broadcast and multicast packets is enabled on an AP.

The AD9431DN-24X does not support this function.

Format

traffic-optimize broadcast-suppression { all | arp | igmp | nd | dhcp | dhcpv6 | mdns | other-broadcast | other-multicast } disable

undo traffic-optimize broadcast-suppression { all | arp | igmp | nd | dhcp | dhcpv6 | mdns | other-broadcast | other-multicast } disable

Parameters

Parameter	Description	Value
all	Indicates whether to enable rate limit for ARP, DHCP, DHCPv6, IGMP, mDNS, and ND multicast and broadcast packets.	-
arp	Indicates whether to enable rate limit for ARP multicast packets.	-
igmp	Indicates whether to enable rate limit for IGMP multicast packets.	-
nd	Indicates whether to enable rate limit for ND broadcast packets.	-
dhcp	Indicates whether to enable rate limit for DHCP broadcast packets.	-
dhcpv6	Indicates whether to enable rate limit for DHCPv6 broadcast packets.	-
mdns	Indicates whether to enable rate limit for mDNS multicast packets.	-
other-broadcast	Indicates whether to enable rate limit for broadcast packets other than ARP, DHCP, DHCPv6, and ND packets.	-
other-multicast	Indicates whether to enable rate limit for multicast packets other than IGMP and mDNS packets.	-

Usage Guidelines

A large number of packets on a device occupy many network resources, affecting network services. To ensure normal running of network services, you can limit the rate of packets of some protocols (such as DHCP and ARP) on APs with a proper range.

The default rate threshold of broadcast and multicast packets of an AP is 256 pps. You can also run the traffic-optimize broadcast-suppression rate-threshold (AP system profile view) command to configure a rate threshold for broadcast and multicast packets, which will override the default rate threshold.

Precautions

When multicast services are enabled, the multicast services may be affected if rate limit for multicast packets is enabled on an AP. In this case, you are advised to run the traffic-optimize broadcast-suppression rate-threshold (AP system profile view) command to adjust the rate limit threshold for multicast packets.
