1.1 Ethernet Port Configuration Commands
1.1.1 broadcast-suppression
Syntax
broadcast-suppression { ratio | bandwidth bandwidth }
undo broadcast-suppression
View
Ethernet port view
Parameters
ratio: Specifies a percentage of the total port bandwidth for broadcasts on the port. The value range is 1 to 100. The smaller the percentage is, the smaller the broadcast traffic is allowed.
bandwidth: Specifies the maximum bandwidth for broadcasts on the port. The value range is 1 to the maximum port bandwidth.
Description
Use the broadcast-suppression command to enable broadcast suppression. When doing this, you can set the percentage of total port bandwidth for broadcasts or set the maximum port bandwidth for broadcasts. Broadcasts that cross the threshold will be suppressed.
Use the undo broadcast-suppression command to restore the default.
The default percentage of the total port bandwidth for broadcasts is 50%.
The broadcast suppression setting you configured with the broadcast-suppression command will overwrite the previous broadcast suppression setting, if any.
Caution:
l You cannot enable both broadcast suppression and multicast suppression 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.
l While broadcast suppression does not work on multicasts, multicast suppression can suppress broadcasts.
l No distinction is made between known multicast and unknown multicast for multicast suppression.
Related commands: multicast-suppression.
Examples
# Set the threshold that triggers broadcast suppression to 40.

1.1.2 copy configuration
Syntax
copy configuration source { interface-type interface-number | interface-name | aggregation-group agg-id } destination { interface-list [ aggregation-group agg-id ] | aggregation-group agg-id }
View
System view
Parameters
interface-type: Source port type.
interface-number: Source port number.
interface-list: Destination port list. You can specify individual ports and port ranges in the list, but the total number of them cannot exceed 10.

Specify a port range in the form of interface-type interface-number to interface-type interface-number where the end port must be greater than the start port.
agg-id: Source or destination aggregation group ID. If it is a source aggregation group, the port with minimum port number is the source port; if it is a destination aggregation group, the configurations of all its member ports change to be consistent with those of the source port.
Description
Use the copy configuration command to copy the configuration of a port to other ports to keep their configurations consistent.
Examples
# Copy the configuration of aggregation group 1 to aggregation group 2.

1.1.21 multicast-suppression
Syntax
multicast-suppression { ratio | bandwidth bandwidth }
undo multicast-suppression
View
Ethernet port view
Parameters
ratio: Specifies a percentage of the total bandwidth for multicasts on the Ethernet port. The value range is 1 to 100. The smaller the ratio is, the smaller the multicast traffic is allowed.
bandwidth: Specifies the maximum bandwidth for multicasts on the port. The value range is 1 to the maximum port bandwidth.
Description
Use the multicast-suppression command to enable multicast suppression. When doing this, you can set the percentage of total port bandwidth for multicasts or set the maximum port bandwidth for multicasts. Multicasts that cross the threshold will be suppressed.
Use the undo multicast-suppression command to disable multicast suppression.
By default, all broadcasts are allowed to pass, that is the ratio argument is set to 100.
The multicast suppression setting you configured with the multicast-suppression command will overwrite the previous multicast suppression setting, if any.
Caution:
l You cannot enable both multicast suppression and broadcast 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. Although the commands are based on ports, the mutual exclusion between these two commands is based on cards.
l While broadcast suppression does not work on multicasts, multicast suppression can suppress broadcasts.
l No distinction is made between known multicast and unknown multicast for multicast suppression.
Related commands: broadcast-suppression.

# Set the threshold that triggers multicast suppression to 40%.
