Ethernet interface commands

Common Ethernet interface commands

bandwidth

Use bandwidth to set the expected bandwidth of an interface.

Use undo bandwidth to restore the default.

Syntax

bandwidth bandwidth-value

undo bandwidth

Default

The expected bandwidth (in kbps) is the interface baud rate divided by 1000.

Views

Ethernet interface view

Predefined user roles

network-admin

Parameters

bandwidth-value: Specifies the expected bandwidth in the range of 1 to 400000000 kbps.

Usage guidelines

The expected bandwidth is an informational parameter used only by higher-layer protocols for

calculation. You cannot adjust the actual bandwidth of an interface by using this command.

Examples

# Set the expected bandwidth of GigabitEthernet 1/0/1 to 1000 kbps.

<Sysname> system-view

[Sysname] interface gigabitethernet 1/0/1

[Sysname-GigabitEthernet1/0/1] bandwidth 1000

Related commands

speed

broadcast-suppression

Use broadcast-suppression to enable broadcast suppression and set the broadcast

suppression threshold.

Use undo broadcast-suppression to disable broadcast suppression.

Syntax

broadcast-suppression { ratio | pps max-pps | kbps max-kbps }

undo broadcast-suppression

2

Default

Ethernet interfaces do not suppress broadcast traffic.

Views

Ethernet interface view

Predefined user roles

network-admin

Parameters

ratio: Sets the broadcast suppression threshold as a percentage of the interface bandwidth. The

value range for this argument is 0 to 100. A smaller value means that less broadcast traffic is allowed

to pass through.

pps max-pps: Specifies the maximum number of broadcast packets that the interface can forward

per second. The value range for the max-pps argument (in pps) is 0 to 1.4881 × the interface

bandwidth.

kbps max-kbps: Specifies the maximum number of kilobits of broadcast traffic that the Ethernet

interface can forward per second. The value range for this argument (in kbps) is 0 to the interface

bandwidth.

Usage guidelines

The broadcast storm suppression features limits the size of broadcast traffic to a threshold on an

interface. When the broadcast traffic on the interface exceeds this threshold, the system drops

packets until the traffic drops below this threshold.

Both the storm-constrain command and the broadcast-suppression command can

suppress broadcast storms on a port. The broadcast-suppression command uses the chip to

physically suppress broadcast traffic. It has less influence on the device performance than the

storm-constrain command, which uses software to suppress broadcast traffic.

For the traffic suppression result to be determined, do not configure both the storm-constrain

broadcast command and the broadcast-suppression command on an interface.

When you configure the suppression threshold in kbps, the actual suppression threshold might be

different from the configured one as follows:

•

If the configured value is smaller than 64, the value of 64 takes effect.

•

If the configured value is greater than 64 but not an integer multiple of 64, the integer multiple of

64 that is greater than and closest to the configured value takes effect.

For the suppression threshold that takes effect, see the prompt on the device.

Examples

# Set the broadcast suppression threshold to 10000 kbps on GigabitEthernet 1/0/1.

<Sysname> system-view

[Sysname] interface gigabitethernet 1/0/1

[Sysname-GigabitEthernet1/0/1] broadcast-suppression kbps 10000

The actual value is 10048 on port GigabitEthernet1/0/1 currently.

The output shows that the value that takes effect is 10048 kbps (157 times of 64), because the chip

only supports step 64.

combo enable

Use combo enable to activate the copper or fiber combo port of a combo interface.

Syntax

combo enable { auto | copper | fiber }

Default

The copper or fiber combo port is automatically activated depending on the medium inserted in the

combo interface.

Views

Ethernet interface view

Predefined user roles

network-admin

Parameters

auto: Automatically identifies the media inserted and activates the corresponding combo port.

copper: Activates the copper combo port. In this case, use twisted pairs to connect the port.

fiber: Activates the fiber combo port. In this case, use optical fibers to connect the port.

Usage guidelines

A combo interface is a logical interface that physically contains one fiber combo port and one copper

combo port on the device panel. The two ports share one forwarding interface. As a result, they

cannot work simultaneously. When you activate either port, the other port is automatically disabled.

You can select to activate the copper combo port or fiber combo port.

This command is available only on devices that support combo interfaces.

If you execute the combo enable auto command on a combo interface and the combo interface

is connected to cables or optical fibers, you can use the display interface command to display

the interface information.

•

If the display interface command output contains "Media type is twisted pair," the copper

combo port is activated.

•

Otherwise, the fiber combo port is activated.

Before using this command, perform the following tasks according to the marks on the device panel:

•

Determine the combo interfaces on your device.

•

Identify the two physical interfaces that belong to each combo interface.

Examples

# Activate the copper combo port of combo interface GigabitEthernet 1/0/1.

<Sysname> system-view

[Sysname] interface gigabitethernet 1/0/1

[Sysname-GigabitEthernet1/0/1] combo enable copper

# Activate the fiber combo port of combo interface GigabitEthernet 1/0/1.

dampening

Use dampening to enable the device to dampen an interface when the interface is flapping.

Use undo dampening to restore the default.

Syntax

dampening [ half-life reuse suppress max-suppress-time ]

undo dampening

Default

Interface dampening is disabled on Ethernet interfaces.

Views

Ethernet interface view

Predefined user roles

network-admin

Parameters

half-life: Specifies the amount of time after which a penalty is decreased, in the range of 1 to

120 seconds. The default value is 54 seconds.

reuse: Specifies the reuse threshold in the range of 200 to 20000. The default value is 750. The

reuse threshold must be less than the suppression threshold.

suppress: Specifies the suppression threshold in the range of 200 to 20000. The default value is

2000.

max-suppress-time: Specifies the maximum amount of time the interface can be dampened, in

the range of 1 to 255 seconds. The default value is 162 seconds (three times the half-life timer).

Usage guidelines

When configuring the dampening command, follow these rules to set the values mentioned above:

•

The ceiling is equal to 2 (Max-suppress-time/Decay) × reuse-limits. It is not user configurable.

•

The configured suppress limit is lower than or equal to the ceiling.

•

The ceiling is lower than or equal to the maximum suppress limit supported.

This command, the link-delay command, and the port link-flap protect enable

command are mutually exclusive on an interface.

This command does not take effect on the administratively down events. When you execute the

shutdown command, the penalty restores to 0, and the interface reports the down event to the

higher layer protocols.

After an interface in down state is dampened, the interface state displayed through the display

interface command is always down.

Examples

# Enable interface dampening on GigabitEthernet 1/0/1.

<Sysname> system-view

[Sysname] interface gigabitethernet 1/0/1

[Sysname-GigabitEthernet1/0/1] dampening

# Enable interface dampening on GigabitEthernet 1/0/1, and set the following parameters:

•

Half life time to 2 seconds.

•

Reuse value to 800.

5

•

Suppression threshold to 3000.

•

Maximum suppression interval to 5 seconds.

Usage guidelines

CAUTION:

The

default command might interrupt ongoing network services. Make sure you are fully aware of

the impacts of this command when you use it in a live network.

This command might fail to restore the default settings for some commands because of command

dependencies or system restrictions. You can use the display this command in interface view to

identify these commands, and use their undo forms or follow the command reference to restore their

default settings. If your restoration attempt still fails, follow the error message instructions to solve

the problem.

Examples

# Restore the default settings for GigabitEthernet 1/0/1.

Use description to configure the description of an interface.

Use undo description to restore the default.

Syntax

statistics for all interfaces of the specified type.

If you specify an interface type and number, this command displays traffic statistics for the specified

interface.
