broadcast-suppression
Syntax
broadcast-suppression { ratio | pps max-pps }
undo broadcast-suppression
View
System view, Ethernet port view
Parameters
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-pps: Maximum number of broadcast packets allowed to be received per second on an Ethernet
port (in pps). The following are the value ranges for the argument:
z In system view, the value range is 1 to 262143.
z In Ethernet port view, the value range is 1 to 148810 for an Ethernet port, and 1 to 262143 for a
GigabitEthernet port.
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.
