Description
Use the broadcast-suppression command to limit broadcast traffic allowed to be received on each
port (in system view) or on a specified port (in Ethernet port view).
Use the undo broadcast-suppression command to restore the default broadcast suppression setting.
The broadcast-suppression command is used to enable broadcast suppression. By default,
broadcast suppression is disabled.
When incoming broadcast traffic exceeds the broadcast traffic threshold you set, the system drops the
packets exceeding the threshold to reduce the broadcast traffic ratio to the specified range, so as to
keep normal network service.
You can use the undo broadcast-suppression command in system view to cancel the broadcast
suppression settings on all ports, or use the broadcast-suppression command in system view to make a
global setting.
Executing the commands in Ethernet port view only takes effect on the current port.
The global broadcast suppression setting configured by the broadcast-suppression command in
system view takes effect on all Ethernet ports in the system except for the reflection ports, stack ports
and ports having their own broadcast suppression settings.
If you configure broadcast-suppression command in both system view and Ethernet port view, the
configuration in Ethernet port view will take effect.
Examples
# Allow incoming broadcast traffic on Ethernet 1/0/1 to occupy at most 20% of the total transmission
capacity of the port and suppress the broadcast traffic that exceeds the specified range.
<Sysname> system-view
System View: return to User View with Ctrl+Z.
[Sysname] interface ethernet 1/0/1
[Sysname-Ethernet1/0/1] broadcast-suppression 20
# Set the maximum number of broadcast packets that can be received per second by the Ethernet 1/0/1
port to 1,000.
[Sysname-Ethernet1/0/1] broadcast-suppression pps 1000
