Ethernet port view

ratio: Specifies the maximum wire speed ratio of the broadcast traffic allowed on 
the port. The value range is 1 to 100, and the default value is 50. The smaller the 
ratio is, the smaller the broadcast traffic is allowed.

bandwidth: Specifies broadcast suppression bandwidth on the port. The value 
range is 1 to the maximum value of port bandwidth.

Use the broadcast-suppression command to set the broadcast suppression ratio 
or broadcast suppression bandwidth.

Use the undo broadcast-suppression command to disable the broadcast 
suppression function.

The default broadcast suppression ratio is 50%.

You can use the broadcast-suppression command repeatedly. The effective 
broadcast suppression ratio value is the one last updated.

You cannot enable both broadcast suppression and multicast suppression 
simultaneously on the same card. Namely, once you have enabled broadcast 
suppression on some ports of a card, you cannot enable multicast suppression 
on the other ports of the card, and vice versa.

■

If multicast suppression is enabled, broadcast packets are also suppressed at 
the same time, while broadcast suppression does not work on multicast 
packets.
