broadcast-suppression

Syntax broadcast-suppression { ratio pps max-pps}

undo broadcast-suppression

View Ethernet interface view, port group view

Parameter ratio: Maximal ratio of broadcast traffic to the total transmission capability of an Ethernet interface. Currently, this argument can only be set to 100.

pps max-pps: Specifies the maximal broadcast packet number per second for an Ethernet interface, in pps, representing packets per second. Currently, the max-ppsargument can only be 190, 380, 760, 1488, 2976, 5952, or 11904.

Description Use the broadcast-suppressioncommand to configure a broadcast storm suppression ratio.

Use the undo broadcast-suppressioncommand to restore the default broadcast storm suppression ratio.

By default, all broadcast traffic is allowed to go through an Ethernet interface, that is, broadcast traffic is not suppressed.

If you execute this command in Ethernet interface view, the configuration takes effect only on the current interface. If you execute this command in port group view, the configuration takes effect on all the ports in the port group.

Note that when broadcast traffic exceeds the maximum value configured, the system will discard the extra packets so that the broadcast traffic ratio falls below the limit to ensure that the network functions properly.

n If you set different suppression ratios in Ethernet interface view or port group view repeatedly, the last configuration takes effect.

Example # Set the maximum broadcast traffic allowed on Ethernet1/0 to 5952 pps.
