Port Basic Configuration Commands

broadcast-suppression { ratio | bps max-bps | pps max-pps }

undo broadcast-suppression

System view, Ethernet port view

ratio: Maximum ratio (in percentage) of the broadcast traffic allowed on a port to the total transmission

capacity of the 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-bps: Maximum number of kilobits of broadcast bits that can be received per second on an Ethernet

port (in step of 64). This argument can be configured only in Ethernet port view.

For a 100-Mbps Ethernet port, the max-bps argument is in the range 64 to 99,968.

For a GigabitEthernet port, the max-bps argument is in the range 64 to 1,000,000.

max-pps: Maximum number of broadcast packets that can be received per second on the specific or all

Ethernet ports (in pps). This argument can be configured either in system view or Ethernet port view.

In Ethernet port view, the max-pps argument ranges from 1 to 1488100.

In GigabitEthernet port view, the max-pps argument ranges from 1 to 14881000.

In system view, the max-pps argument ranges from 1 to 148810000.

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.
