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
# Set the expected bandwidth of GigabitEthernet 1/0/1.1 to 1000 kbps.
<Sysname> system-view
[Sysname] interface gigabitethernet 1/0/1.1

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
Default
Ethernet interfaces do not suppress broadcast traffic.
Views

Predefined user roles
network-admin
context-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.
The configured suppression threshold value in pps or kbps might be converted into a multiple of a step supported by the chip. As a result, the effective suppression threshold might be different from the configured one. To determine the suppression threshold that takes effect, see the prompts 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

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.

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
context-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 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.
Do not enable the dampening function on an interface with spanning tree protocols enabled.
After an interface in down state is dampened, the interface state displayed through the display interface command, MIB, or Web 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.
· Suppression threshold to 3000.
· Maximum suppression interval to 5 seconds.

Usage guidelines
With TxRx-mode generic flow control configured, an interface can both send and receive flow control frames:
· When congested, the interface sends a flow control frame to its peer.
· Upon receiving a flow control frame from the peer, the interface suspends sending packets.
To implement flow control on a link, enable generic flow control at both ends of the link.
Examples
# Enable TxRx-mode generic flow control on GigabitEthernet 1/0/1.

loopback
CAUTION: After you enable loopback testing on an Ethernet interface, the interface does not forward data traffic. |
Use loopback to enable loopback testing on an Ethernet interface.
Use undo loopback to disable loopback testing on an Ethernet interface.
Syntax

context-admin
Parameters
external: Enables external loopback testing on the Ethernet interface.
internal: Enables internal loopback testing on the Ethernet interface.
Usage guidelines
After you enable loopback testing on an Ethernet interface, the Ethernet interface switches to full duplex mode. After you disable loopback testing, the Ethernet interface restores to its duplex setting.
The shutdown and loopback commands are mutually exclusive.
Examples
# Enable internal loopback testing on GigabitEthernet 1/0/1.

multicast-suppression
Use multicast-suppression to enable multicast storm suppression and set the multicast storm suppression threshold.
Use undo multicast-suppression to disable multicast storm suppression.
Syntax
multicast-suppression { ratio | pps max-pps | kbps max-kbps }
undo multicast-suppression
Default
Ethernet interfaces do not suppress multicast traffic.
Views
Ethernet interface view
Predefined user roles
network-admin
context-admin
Parameters
ratio: Sets the multicast suppression threshold as a percentage of the interface bandwidth. The value range for this argument (in percentage) is 0 to 100. A smaller value means that less multicast traffic is allowed to pass through.
pps max-pps: Specifies the maximum number of multicast 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 multicast 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 multicast storm suppression feature limits the size of multicast traffic to a threshold on an interface. When the multicast 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 multicast-suppression command can suppress multicast storms on a port. The multicast-suppression command uses the chip to physically suppress multicast traffic. It has less influence on the device performance than the storm-constrain command, which uses software to suppress multicast traffic.
For the traffic suppression result to be determined, do not configure both the storm-constrain multicast command and the multicast-suppression command on an interface.
The configured suppression threshold value in pps or kbps might be converted into a multiple of a step supported by the chip. As a result, the effective suppression threshold might be different from the configured one. To determine the suppression threshold that takes effect, see the prompts on the device.
Examples
# Set the multicast storm suppression threshold to 10000 kbps on GigabitEthernet 1/0/1.
<Sysname> system-view
[Sysname] interface gigabitethernet 1/0/1

Parameters
bridge: Specifies the Layer 2 mode.
route: Specifies the Layer 3 mode.
Usage guidelines
CAUTION: Changing the link mode of an Ethernet interface also restores all commands (except shutdown and combo enable) on the Ethernet interface to their defaults in the new link mode. |
Interfaces operate differently depending on the hardware structure of interface cards. For a device:
· Some Ethernet interfaces can operate only as Layer 2 Ethernet interfaces (in bridge mode).
· Some Ethernet interfaces can operate only as Layer 3 Ethernet interfaces (in route mode).
· Some Ethernet interfaces can operate either as Layer 2 or Layer 3 Ethernet interfaces. You can use this command to set the link mode to bridge or route for these Ethernet interfaces.
Examples
# Configure GigabitEthernet 1/0/1 to operate in Layer 2 mode.

Parameters
10: Sets the interface speed to 10 Mbps.
100: Sets the interface speed to 100 Mbps.
1000: Sets the interface speed to 1000 Mbps.
auto: Enables the interface to negotiate a speed with its peer.
Usage guidelines
For an Ethernet copper port, use the speed command to set its speed to match the speed of the peer interface. Support of copper ports for keywords of this command varies by copper port type. For more information, use the speed ? command in interface view. If the system does not prompt that operation failed when you configure a speed for a copper port, the copper port supports this speed. Otherwise, the copper port does not support this speed.
For a fiber port, use the speed command to set its speed to match the rate of a transceiver module. Support of fiber ports for keywords of this command varies by fiber port type. For more information, use the speed ? command in interface view. If the system does not prompt that operation failed when you configure a speed for a fiber port, the fiber port supports this speed. Otherwise, the fiber port does not support this speed.
Additionally, you must select a speed for a fiber port according to the transceiver module installed to ensure that the transceiver module can be used properly. If the transceiver module installed in a fiber port does not support the speed for the fiber port, the transceiver module cannot be used. For example, the transceiver module cannot be used if the following conditions exist:
· The transceiver module installed in an SFP+ fiber port is an SFP GE transceiver module and the speed 10000 command is executed on the fiber port.
· The transceiver module installed in an SFP+ fiber port is an SFP 10-GE transceiver module and the speed 1000 command is executed on the fiber port.

Predefined user roles
network-admin
context-admin
Parameters
ratio: Sets the unknown unicast suppression threshold as a percentage of the interface bandwidth. The value range for this argument (in percentage) is 0 to 100. A smaller value means that less unknown unicast traffic is allowed to pass through.
pps max-pps: Specifies the maximum number of unknown unicast 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 unknown unicast 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 unknown unicast storm suppression feature limits the size of unknown unicast traffic to a threshold on an interface. When the unknown unicast traffic on the interface exceeds this threshold, the system discards packets until the unknown unicast traffic drops below this threshold.
The configured suppression threshold value in pps or kbps might be converted into a multiple of a step supported by the chip. As a result, the effective suppression threshold might be different from the configured one. To determine the suppression threshold that takes effect, see the prompts on the device.
Examples
# Set the unknown unicast storm suppression threshold to 10000 kbps on GigabitEthernet 1/0/1.

Parameters
all: Disables storm control for all types of traffic: multicast and broadcast.
broadcast: Enables or disables broadcast storm control.
multicast: Enables or disables multicast storm control.
pps: Sets storm control thresholds in pps.
upperlimit: Sets the upper threshold. If you specify the pps keyword, the value range for the upperlimit argument is 0 to 1.4881 × the interface bandwidth.
lowerlimit: Sets the lower threshold. If you specify the pps keyword, the value range for the lowerlimit argument is 0 to 1.4881 × the interface bandwidth.
Usage guidelines
After you configure storm control for a type of traffic, the device collects the statistics for the type of traffic at the interval configured by using the storm-constrain interval command. When the type of traffic exceeds its upper threshold, the interface takes an action configured by using the storm-constrain control command.
The storm-constrain, broadcast-suppression, multicast-suppression, and unicast-suppression commands can suppress storms on an interface. The broadcast-suppression, multicast-suppression, and unicast-suppression commands use the chip to physically suppress traffic. They have less influence on the device performance than the storm-constrain command, which uses software to suppress traffic.
For the traffic suppression result to be determined, do not configure both storm control and storm suppression for the same type of traffic.
When configuring this command, make sure upperlimit is greater than lowerlimit.
Examples
# Enable broadcast storm control on GigabitEthernet 1/0/1 and set the upper and lower thresholds to 200 pps and 150 pps, respectively.

Parameters
block: Blocks the type of traffic exceeding the upper threshold and forwards other types of traffic. Even though the interface does not forward the blocked type of traffic, it still counts the traffic. When the blocked type of traffic drops below the lower threshold, the port begins to forward the traffic.
shutdown: Goes down automatically and stops forwarding any traffic. When the type of traffic exceeding the upper threshold drops below the lower threshold, the interface does not forward traffic. To bring up the interface, use the undo shutdown command or disable storm control on the interface.

Usage guidelines
This feature takes effect only on Layer 3 Ethernet interfaces/subinterfaces, Layer 3 aggregate interfaces, and Layer 3 Reth interfaces. These interfaces are referred to as interfaces in this command.
Typically, use the default settings.
With this feature enabled, when an interface receives a packet, the interface operates as follows:
· If the destination MAC address of the packet is the MAC address of the interface, the interface accepts and processes the packet.
· If the destination MAC address of the packet is not the MAC address of the interface, the interface drops the packet.
With this feature disabled, an interface accepts and processes a packet, without checking the destination MAC address of the packet.

Parameters
size: Sets the MTU in bytes. The value range for this argument is 46 to 1560.
Usage guidelines
A smaller MTU size results in more fragments. When you set the MTU for an interface, consider QoS queue lengths, for example, consider that the default FIFO queue length is 75. To prevent a too small MTU from causing packet drops in QoS queuing, you can perform one of the following configurations:
· Tune the MTU with the mtu command.
· Tune QoS queue lengths with the qos fifo queue-length command.
