Port Basic Configuration Commands

broadcast-suppression { ratio | bps max-bps }

undo broadcast-suppression

System view, Ethernet port view

ratio: Maximum ratio 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 (in Kbps) of broadcast traffic that can be received per second on an

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

For a 100Mbps 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.

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.
