broadcast-suppression
Syntax
broadcast-suppression { ratio | pps max-pps }
undo broadcast-suppression
View
Layer 2 Ethernet interface view, port group view
Default Level
2: System level
Parameters
ratio: Maximum percentage of broadcast traffic to the total transmission capability of an Ethernet
interface, in the range 1 to 100. The smaller the ratio, the less broadcast traffic is allowed to pass
through the interface.
pps max-pps: Specifies the maximum number of broadcast packets that can be forwarded on the
Ethernet interface(s) per second.
z
For a 100-Mbps port, this value ranges from 1 to 148810 (in pps).
z
For a 1-Gbps port, this value ranges from 1 to 1488100 (in pps).
z
For a 10-Gbps port, this value ranges from 1 to 14881000 (in pps).
Note that:
z
When a suppression granularity larger than 1 is specified on the device, the value of the pps
keyword should be no smaller than and an integral multiple of the granularity. The broadcast
suppression threshold value configured through this keyword on an Ethernet interface may not be
the one that actually takes effect. To display the actual broadcast suppression threshold value on
an Ethernet interface, you can use the display interface command.
z
When no suppression granularity is specified or the suppression granularity is set to 1, the value of
the pps or keyword should be no smaller than 1, and the broadcast suppression threshold value is
the one that actually takes effect on the Ethernet interface.
Description
Use the broadcast-suppression command to set a broadcast traffic threshold on one or multiple
Ethernet ports.
Use the undo broadcast-suppression command to restore the default.
By default, all broadcast traffic is allowed to pass through an Ethernet interface, that is, broadcast traffic
is not suppressed.
