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 AP.
The undo traffic-optimize broadcast-suppression rate-threshold command restores the default threshold of broadcast and multicast packets on an AP.
By default, the rate threshold for other-broadcast and other-multicast is 16 pps, and that for other parameters 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 a rate threshold. |
For other-broadcast and other-multicast, the value is an integer that ranges from 0 to 1024, in pps. The default value is 16. For other parameters: The value is an integer that ranges from 64 to 1024, in pps. The default value is 256. |
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 AP, 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.
