R3303-HP HSR6800 Routers Interface Command Reference

31
Default
Ethernet interfaces do not suppress broadcast traffic.
Views
Layer 2 Ethernet interface view, port group view
Default command level
2: System level
Parameters
ratio: Sets the broadcast suppression threshold as a percentage of the maximum interface rate. The
smaller the percentage, the less broadcast traffic is allowed to be received. This argument is in the range
of 1 to 100.
pps max-pps: Specifies the maximum number of broadcast packets that the Ethernet interface can receive
per second. The max-pps argument is in the range of 1 to 1488100 pps.
kbps max-kbps: Specifies the maximum number of kilobits of broadcast traffic that the Ethernet interface
can receive per second. The max-kbps argument is in the range of 1 to 1000000 kbps.
• When the pps or kbps keyword is specified, and a suppression granularity larger than 1 is
specified on the device, the value of the pps or kbps keyword must be no smaller than, and an
integer multiple of, the granularity. The broadcast suppression threshold value configured through
this keyword on an Ethernet interface might not be the one that actually takes effect. To display the
actual broadcast suppression threshold value on an Ethernet interface, use the display interface
command.
• When the pps or kbps keyword is not specified, or the suppression granularity is set to 1, the value
of the pps or kbps keyword must be no smaller than 1, and the broadcast suppression threshold
value is the one that actually takes effect on the Ethernet interface.
Usage guidelines
In Ethernet interface view, the configuration takes effect only on the interface. In port group view, the
configuration takes effect on all ports in the port group.
When the received broadcast traffic exceeds the broadcast suppression threshold, the interface discards
broadcast packets until broadcast traffic drops below the threshold.
If you set different broadcast suppression thresholds in Ethernet interface view or port group view multiple
times, the one configured last takes effect.
For a particular type of traffic, configure either storm suppression or storm control, but not both. If both of
them are configured, you might fail to achieve the expected storm control effect.
