Chapter 1 Ethernet Port Configuration Commands

1.1 Ethernet Port Configuration Commands

1.1.1 broadcast-suppression

Syntax

broadcast-suppression{ ratio| bandwidthbandwidth}

undobroadcast-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-suppressioncommand 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-suppressioncommand 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.


3/33



1-2

Caution:

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.

While broadcast suppression does not work on multicasts, multicast suppression

can suppress broadcasts.

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.

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.


4/33



1-3

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 an individual port in the

form of interface-type interface-number where interface-type is the port type and

interface-numberis the port number. Specify a port range in the form of interface-typeinterface-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 configurationcommand 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.

Parameters

interface-type: Specifies the port type.

interface-number: Specifies the port number.

Description

Use the display interfacecommand to view the configuration information on the port.

If the port type and number are not specified when displaying the port information,

the information of all the ports will be displayed.

If only the port type is specified, all the information of the ports of this type will be

displayed.

If both port type and port number are specified, the information of the designatedport will be displayed.

The system supports discrete values of Jumbo frame size ranging from 1,552 to 10,240.

However, effective Jumbo frame values fall into several sections: the effective Jumbo

frame sizes for the 1,552-9,022 section are 1,552 and 9,022, that for the 9,023-9,192

section is 9,192, and that for the 9,193-10,240 section is 10,240.

1.1.21 multicast-suppression

Syntax

multicast-suppression{ ratio| bandwidthbandwidth}

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.


24/33



1-23

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-suppressioncommand to disable multicast suppression.

By default, all broadcasts are allowed to pass, that is the ratioargument 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:

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.

While broadcast suppression does not work on multicasts, multicast suppression

can suppress broadcasts.

No distinction is made between known multicast and unknown multicast for

multicast suppression.

Related commands: broadcast-suppression.

Examples

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