ratio: Maximal ratio of broadcast traffic to the total transmission capability of an Ethernet interface. It ranges between 1 to 100 and defaults to 100.

The smaller the ratio, the less broadcast traffic allowed through the interface.

Description

Use the broadcast-suppression command to configure a broadcast storm suppression ratio.

Use the undo broadcast-suppression command 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 configurations take effect only on the current interface. If you execute this command in port-group view, the configurations take effect on all 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.

& Note:

If you set different suppression ratios in Ethernet interface view or port-group view for multiple times, the latest configuration takes effect.

Example

# Allow broadcast traffic equivalent to 20% of the total transmission capability of Ethernet1/0 to pass and suppress the excessive broadcast packets.

To sample network traffic within a period of time for an interface, you need to reset the original interface statistics.

l If neither interface type nor interface number is specified, all interface information will be reset;

l If only interface type is specified, then only information of this particular type of interface will be reset.

l If both interface type and interface number are specified, then only information of the specified interface will be reset.

Example

# Clear the statistics of Ethernet 1/0/1.

<Sysname> reset counters interface ethernet 1/0/1

1.1.25 shutdown

Syntax

shutdown

undo shutdown

View

Ethernet interface view

Parameter

None

Description

Use the shutdown command to shut down an Ethernet interface.

Use the undo shutdown command to turn on Ethernet interface.

In certain circumstances, modification to the interface parameters does not immediately take effect, and therefore, you need to shut down the relative interface to make the modification work.

Example

# Shut down the interface Ethernet 1/0/1.

<Sysname> system-view

System View: return to User View with Ctrl+Z.

[Sysname] interface ethernet 1/0/1

[Sysname-Ethernet1/0/1] shutdown

# Turn on the interface Ethernet 1/0/1.

<Sysname> system-view

System View: return to User View with Ctrl+Z.

[Sysname] interface ethernet 1/0/1

[Sysname-Ethernet1/0/1] undo shutdown

1.1.26 speed

Syntax

speed { 10 | 100 | 1000 | auto }

undo speed

View

Ethernet interface view

Parameter

10: Indicates that the interface rate is 10 Mbps.

100: Indicates that the interface rate is 100 Mbps.

1000: Indicates that the interface rate is 1000 Mbps.

auto: Indicates that the interface rate is in the auto-negotiation state.

Description

Use the speed command to configure Ethernet interface data rate.

Use the undo speed command to restore Ethernet interface data rate.

By default, Ethernet interface data rate is automatically negotiated between peer Ethernet interfaces.

Note that the following:

l The Combo port does not support the speed command.

l The speed 1000 command is only applicable to Gigabit Ethernet interface.

Related command: duplex.

Example

# Configure data rate for the interface Ethernet 1/0/1 to 100 Mbps.

<Sysname> system-view

System View: return to User View with Ctrl+Z.

[Sysname] interface ethernet 1/0/1

[Sysname-Ethernet1/0/1] speed 100

1.1.27 virtual-cable-test

Syntax

virtual-cable-test

View

Ethernet interface view

Parameter

None

Description

Use the virtual-cable-test command to enable the virtual cable test for an Ethernet interface and to display the testing result. The tested items include:

l Cable status: Could be normal, abnormal, abnormal-open, abnormal-short, and failure;

l Cable length;

l Pair Impedance mismatch;

l Pair skew;

l Pair swap;

l Pair polarity;

l Insertion loss;

l Return loss;

l Near-end crosstalk.

By default, virtual cable test is disabled.

Note:

l When the cable is functioning properly, the cable length in the test result represents no meaning;

l When the cable is not functioning properly, the cable length in the test result represents the length from the current interface to the failed position.

l For the 100M port, current device does not support getting the total cable length when the cable under normal status.

& Note:

The virtual-cable-test command is not supported on a Combo optical port.

Example

# Enable the virtual cable test for the interface Ethernet 1/0/1.

<Sysname> system-view

[Sysname] interface ethernet 1/0/1

[Sysname-Ethernet1/0] virtual-cable-test

Cable status: abnormal(open), 7 metres

Pair Impedance mismatch: yes

Pair skew: 4294967294 ns

Pair swap: swap

Pair polarity: normal

Insertion loss: 7 db

Return loss: 7 db

Near-end crosstalk: 7 db

Description

Use the link-aggregation group description command to configure a name for the specified link aggregation group.

Use the undo link-aggregation group description command to remove the name of the specified link aggregation group.

Note that the configuration of dynamic LACP link aggregation groups including their group names cannot survive a reboot even if you have saved configuration with the save command before that.

Related command: display link-aggregation verbose.

Example

# Name link aggregation group 22 as abc.

<Sysname> system-view

undo link-aggregation group agg-id

View

System view

Parameter

agg-id: Link aggregation group ID. Its value range varies by device.

manual: Manual link aggregation mode.

static: Static LACP link aggregation mode.

Description

Use the link-aggregation group mode command to create a manual or static LACP link aggregation group.

Use the undo link-aggregation group command to remove a link aggregation group. If the group is functioning as a service loop group, this can result in the removal of the service loop group.

You can use the undo form of the command to remove a dynamic LACP link aggregation group even though you cannot manually create one. After that, the member ports in the group form another group with an ID that can be the same as or different than the old one.

Related command: display link-aggregation summary.

Example

# Create manual link aggregation group 22.

<Sysname> system-view

[Sysname] link-aggregation group 22 mode manual

Description

Use the link-aggregation group service-type command to create a service loop group or modify the service supported by an existing service loop group.

Use the link-aggregation group mode command to remove a service loop group.

You can only use a manual link aggregation group to create a service loop group. This group can support MPLS or any service combinations of IPv6, IPv6 multicast, and tunnel. If another service loop group is providing the intended service, however, your creation or service-type modification attempt will fail.

Example

# Configure link aggregation group 5 as a tunnel service loop group.

<Sysname>system-view

System View: return to User View with Ctrl+Z.

[Sysname] link-aggregation group 5 service-type tunnel

2.1.12 port link-aggregation group
