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 {copper |fiber }
Default
The copper combo port of a combo interface is activated.
Views
Ethernet interface view
Predefined user roles
network-admin
Parameters
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.
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.
<Sysname> system-view
[Sysname] interface gigabitethernet 1/0/1
[Sysname-GigabitEthernet1/0/1] combo enable fiber

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.
<Sysname> system-view
[Sysname] interface gigabitethernet 1/0/1
[Sysname-GigabitEthernet1/0/1] default
description
Use description to configure the description of an interface.
Use undo description to restore the default.
Syntax

Field Description
Current state
Physical link state of the interface:
•Administratively DOWN—The interface has been shut
down by using the shutdown command.
•DOWN—The interface is administratively up, but its physical
state is down (possibly because no physical link exists or the
link has failed).
•DOWN ( Link-Aggregation interface down )—The
aggregate interface to which the interface belongs has been
shut down by using the shutdown command.
•mac-address moving down—The interface has been shut
down by the MAC address move suppression feature.
•MAD ShutDown—The interface has been shut down by
IRF MAD. This state occurs if the interface is on an IRF
fabric placed in Recovery state after an IRF split.
•OFP DOWN—The interface has been shut down by
OpenFlow.
•Storm-Constrain—The interface has been shut down
because the storm control feature detected that unknown
unicast traffic, multicast traffic, or broadcast traffic exceeded
the upper threshold.
•STP DOWN—The interface has been shut down by the
BPDU guard feature.
•UP—The interface is both administratively and physically
up.
Line protocol state
Data link layer state of the interface. The state is determined
through automatic parameter negotiation at the data link layer.
•UP—The data link layer protocol is up.
•UP (spoofing)—The data link layer protocol is up, but the
link is an on-demand link or does not exist. This attribute is
typical of null interfaces and loopback interfaces.
•DOWN—The data link layer protocol is down.
•DOWN (protocols)—The data link layer has been shut
down by protocols included in the parentheses. Available
protocols include:
{DLDP—Shuts down the data link layer when it detects
that the link is unidirectional.
{OAM—Shuts down the data link layer when it detects a
remote link failure.
{LAGG—Shuts down the data link layer when it detects
that the aggregate interface does not have Selected
ports.
{BFD—Shuts down the data link layer when it detects a
link failure.
Bandwidth Expected bandwidth of the interface.
Maximum transmission unit MTU of the interface.

Field Description
Internet protocol processing: Disabled The interface is not assigned an IP address and cannot process
IP packets.
Internet address IP address of the interface. The primary attribute indicates that
the address is the primary IP address.
IP packet frame type IPv4 packet framing format.
hardware address MAC address of the interface.
IPv6 packet frame type IPv6 packet framing format.
Port priority Port priority of the interface.
Loopback is set internal An internal loopback test is running on the interface. This field
depends on your configuration .
Loopback is set external An external loopback test is running on the interface. This field
depends on your configuration.
Loopback is not set No loopback test is running on the interface. This field depends
on your configuration.
10Mbps-speed mode The interface is operating at 10 Mbps. This field depends on your
configuration and the link parameter negotiation result.
100Mbps-speed mode The interface is operating at 100 Mbps. This field depends on
your configuration and the link parameter negotiation result.
1000Mbps-speed mode The interface is operating at 1000 Mbps. This field depends on
your configuration and the link parameter negotiation result.
10Gbps-speed mode The interface is operating at 10 Gbps. This field depends on your
configuration and the link parameter negotiation result.
Unknown-speed mode The speed of the interface is unknown because the speed
negotiation fails or the interface is physically disconnected.
half-duplex mode The interface is operating in half duplex mode. This field depends
on your configuration and the link parameter negotiation result.
full-duplex mode The interface is operating in full duplex mode. This field depends
on your configuration and the link parameter negotiation result.
unknown-duplex mode The duplex mode of the interface is unknown because the duplex
mode negotiation fails or the interface is physically disconnected.
Link speed type is autonegotiation The interface is configured with the speed auto command.
Link speed type is force link The interface is manually configured with a speed (for example,
1000 Mbps) by using the speed command.
link duplex type is autonegotiation The interface is configured with the duplex auto command.
link duplex type is force link The interface is manually configured with a duplex mode (for
example, half or full) by using the duplex command.
Flow-control is not enabled
Generic flow control is disabled on the interface. This field
depends on your configuration and the link parameter negotiation
result.
Maximum frame length Maximum length of Ethernet frames allowed to pass through the
interface.
Allow jumbo frame to pass The interface allows jumbo frames to pass through.
Broadcast max- Broadcast storm suppression threshold in ratio, pps, or kbps. The
unit of the threshold depends on your configuration.
