Syntax
broadcast-suppression { ratio | pps max-pps }
undo broadcast-suppression
Default
Ethernet interfaces do not suppress broadcast traffic.
Views
Layer 2 Ethernet interface view, port group view
Default command level
2: System level
Parameters
ratio: Sets the broadcast suppression threshold as a percentage of the maximum interface rate. The
smaller the percentage, the less broadcast traffic is allowed to be received. This argument is in the range
of 1 to 100.
pps max-pps: Specifies the maximum number of broadcast packets that the Ethernet interface can receive
per second. The value range for the max-pps argument varies by device model. For more information,
see About the Command References for HP Unified Wired-WLAN Products.
When the pps keyword is specified and the suppression granularity is larger than 1, the suppression
•
threshold must be no smaller than, and a multiple of, the granularity. The broadcast suppression
threshold value configured through this keyword on an Ethernet interface might not be the one that
actually takes effect. To display the actual broadcast suppression threshold value on an Ethernet
interface, use the display interface command.
When the pps keyword is not specified or the suppression granularity is 1, follow these guidelines:
•
The configured broadcast suppression threshold value must be no smaller than 1.
The configured broadcast suppression threshold value is the one that actually takes effect on the
Ethernet interface.
Usage guidelines
In Ethernet interface view, the configuration takes effect only on the interface. In port group view, the
configuration takes effect on all the ports in the port group.
When the received broadcast traffic exceeds the broadcast suppression threshold, the interface discards
broadcast packets until broadcast traffic drops below the threshold.
If you set different broadcast suppression thresholds in Ethernet interface view or port group view multiple
times, the one configured most recently takes effect.
Examples
# Set the broadcast suppression threshold to 20% on Ten-GigabitEthernet 1/0/1.
<Sysname> system-view
[Sysname] interface Ten-gigabitethernet 1/0/1
[Sysname-Ten-GigabitEthernet1/0/1] broadcast-suppression 20
# Set the broadcast suppression threshold to 20% on all ports in the manual port group named group1.
<Sysname> system-view
[Sysname] port-group manual group1
[Sysname-port-group-manual-group1] group-member Ten-GigabitEthernet 1/0/1
[Sysname-port-group-manual-group1] group-member Ten-GigabitEthernet 1/0/2
