traffic-optimize broadcast-suppression rate-threshold (AP system profile view)

traffic-optimize broadcast-suppression rate-threshold (AP system profile view)

Function

The traffic-optimize broadcast-suppression rate-threshold command sets a rate threshold for broadcast and multicast packets on an RU.

The undo traffic-optimize broadcast-suppression rate-threshold command restores the default threshold of broadcast and multicast packets on an RU.

The default rate threshold is 256 pps.

The AD9431DN-24X does not support this function.

Format

traffic-optimize broadcast-suppression { arp | igmp | nd | dhcp | dhcpv6 | mdns | other-broadcast | other-multicast } rate-threshold threshold-value

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

Parameters

Parameter

Description

Value

arp

Specifies ARP broadcast packets.

-

igmp

Specifies IGMP multicast packets.

-

nd

Specifies ND broadcast packets.

-

dhcp

Specifies DHCP broadcast packets.

-

dhcpv6

Specifies DHCPv6 broadcast packets.

-

mdns

Specifies mDNS multicast packets.

-

other-broadcast

Specifies broadcast packets other than ARP, DHCP, DHCPv6, and ND packets.

-

other-multicast

Specifies multicast packets other than IGMP and mDNS packets.

-

rate-threshold threshold-value

Specifies the rate threshold.

The value is an integer that ranges from 64 to 1024, in pps. The default value is 256.

2: Configuration level

Usage Guidelines

Before setting a rate threshold for broadcast and multicast packets, run the undo traffic-optimize broadcast-suppression disable command to enable rate limit for broadcast and multicast packets.

After you run the traffic-optimize broadcast-suppression rate-threshold command to configure a rate threshold for broadcast and multicast packets on an RU, the configured threshold will override the default rate threshold. The actual rate of broadcast and multicast packets will not exceed the configured rate threshold. If a large rate threshold is set, the expected network protection effect is not achieved. If a small rate threshold is set, broadcast and multicast packets may be lost. In most cases, use the default rate threshold unless otherwise specified.

Example

# Set the rate threshold for ARP broadcast packets in AP system profile system1 to 300 pps.
