1.1.1 Port Basic Configuration Commands

1.1.2 broadcast-suppression

Syntax
broadcast-suppression { ratio | pps max-pps }
undo broadcast-suppression
View
System view or Ethernet port view
Parameter
ratio: Maximum ratio of the received broadcast traffic to the total bandwidth on an
Ethernet port. The value ranges from 1 to 100 (in step of 1) and defaults to 100. The
smaller the ratio is, the less broadcast traffic is allowed.
max-pps: Maximum number of broadcast packets allowed to be received per second
on an Ethernet port (in pps).
In system view, the max-pps argument is in the range of 1 to 262,143.
In Ethernet port view, the max-pps argument is in the range of 1 to 148,810.
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 reasonable 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.
