Ethernet interface commands Common Ethernet interface commands bandwidth Use bandwidth to configure the expected bandwidth of an interface. Use undo bandwidth to restore the default. bandwidth bandwidth-value undo bandwidth The expected bandwidth (in kbps) is the interface baud rate divided by 1000. Ethernet interface view bandwidth-value: Specifies the expected bandwidth in the range of 1 to 400000000 kbps. The expected bandwidth of an interface affects the bandwidth assignment with CBQ. For more information, see ACL and QoS Configuration Guide. # Set the expected bandwidth of interface GigabitEthernet 1/0/1 to 1000 kbps. [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 restore the default. broadcast-suppression { ratio pps max-pps kbps max-kbps } 1

undo broadcast-suppression Ethernet interfaces do not suppress broadcast traffic. Layer 2 Ethernet interface view ratio: Sets the broadcast suppression threshold as a percentage of the maximum interface rate. The value range for this argument is 0 to 100. The smaller the percentage, the 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 maximum interface rate. For example, the value range for this argument is 0 to 1488100 on a GE interface. 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 maximum interface rate. You can use the broadcast storm suppression function to limit the size of broadcast traffic 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 storm-constrain and broadcast-suppression can suppress broadcast storm on a port. The storm-constrain command uses software to suppress broadcast traffic, and it affects the device performance to a certain extent. The broadcast-suppression command uses the chip to physically suppress broadcast traffic, and it has less influence on the device performance than the storm-constrain command. Do not configure the storm constrain command and the broadcast-suppression command at the same time. Otherwise, the traffic suppression result is not determined. 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. To determine the suppression threshold that takes effect, see the prompts on the device. # Set the broadcast suppression threshold to 10000 kbps on GigabitEthernet 1/0/1. [Sysname] interface gigabitethernet 1/0/1 [Sysname-GigabitEthernet1/0/1] broadcast-suppression kbps 10000 Related commands multicast-suppression unicast-suppression 2

combo enable (only applicable to HP 5130-24G-SFP-4SFP+ EI Switch switches) Use combo enable to activate the copper or fiber combo port of a combo interface. combo enable { copper fiber } The copper combo port of a combo interface is activated. Ethernet interface view 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. 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. For more information about the number of combo interfaces, see the installation guide. default # Activate the copper combo port of combo interface GigabitEthernet 1/0/1. [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] interface gigabitethernet 1/0/1 [Sysname-GigabitEthernet1/0/1] combo enable fiber Use default to restore the default settings for an Ethernet interface. default Ethernet interface view 3

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 for reasons such as command dependencies or system restrictions. Use the display this command in interface view to identify these commands, and then 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 resolve the problem. # Restore the default settings for interface GigabitEthernet 1/0/1. [Sysname] interface gigabitethernet 1/0/1 [Sysname-GigabitEthernet1/0/1] default description Use description to change the description of an interface. Use undo description to restore the default. description text undo description The description of an interface is the interface name plus Interface (for example, GigabitEthernet1/0/1 Interface). Ethernet interface view text: Specifies the interface description, a case-sensitive string of 1 to 255 characters. # Change the description of interface GigabitEthernet 1/0/1 to lanswitch-interface.

Cause for the physical link state of an interface to be DOWN: Administratively The port is manually shut down by using the shutdown command. To restore the physical state of the interface, use the undo shutdown command. DOWN ( Link-Aggregation interface down ) When an aggregate interface is shut down, the physical state of all member ports of the aggregate interface becomes DOWN. DOWN (Loopback detection down) The port is shut down because the loopback detection module has detected loops. DOWN ( Monitor-Link uplink down ) The port is shut down because the monitor link module has detected that the uplink is down. MAD ShutDown After an IRF split, the state of all interfaces except the excluded ports in the IRF in recovery state is set to DOWN. Not connected No physical connection exists (possibly because the network cable is disconnected or faulty). Storm-Constrain The port is shut down because the unknown unicast traffic, multicast traffic, or broadcast traffic exceeds the upper limit. STP DOWN The port is shut down by the STP BPDU guard function. Port Security Disabled The port is shut down by the intrusion detection mechanism because the port receives illegal packets. Standby The interface is in the Standby state. 18

Use undo eee enable to restore the default. eee enable undo eee enable EEE is disabled. Ethernet interface view With the EEE function, a link-up port enters the low power state if it has not received any packet for a certain period of time. The time period depends on the chip specifications and is not configurable. When a packet arrives later, the port enters the normal state. # Enable EEE on GigabitEthernet 1/0/1.

Ethernet interface view To implement flow control on a link, enable the generic flow control function at both ends of the link. TxRx-mode generic flow control enables an Ethernet interface to perform the following actions: Receive common pause frames from its peer. Send common pause frames to notify its peer of congestions. With the flow-control command 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. # Enable TxRx-mode generic flow control on the interface GigabitEthernet 1/0/1. [Sysname] interface gigabitethernet 1/0/1 [Sysname-GigabitEthernet1/0/1] flow-control flow-control receive enable Use flow-control receive enable to enable Rx-mode generic flow control on an Ethernet port. Use undo flow-control to disable Rx-mode generic flow control on an Ethernet interface. flow-control receive enable undo flow-control Rx-mode generic flow control is disabled on Ethernet interfaces. Ethernet interface view With the flow-control receive enable command configured, an interface can receive, but not send, flow control frames. When the interface receives a flow control frame from its peer, it suspends sending packets to the peer. When traffic congestion occurs on the interface, it cannot send flow control frames to the peer. To handle unidirectional traffic congestion on a link, configure the flow-control receive enable command at one end, and the flow-control command at the other. To enable both ends of the link to handle traffic congestion, configure the flow-control command at both ends. 23
