Configuring Ethernet interfaces All configuration tasks in this chapter are independent and optional. You can perform these configuration tasks in any order. Overview Ethernet is the most widespread wired LAN technology due to its flexibility, simplicity, and easy implementation. Your device supports the following types of Ethernet interfaces: • Layer 2 Ethernet interfaces—Physical Ethernet interfaces operating at the data link layer (Layer 2) to forward traffic within a subnet between hosts.
The LINK LED of a GE combo interface might be on when you insert or remove a transceiver module into or from the combo interface whose fiber combo port is active on an MSR50 router, SIC-1GEC module, XMIM-16FSW module, or XMIM-24FSW module. To solve the problem, shut down the combo interface with the shutdown command and then bring it up with the undo shutdown command.
Step Command Remarks 1. Enter system view. system-view N/A 2. Enter Ethernet interface view. interface interface-type interface-number N/A 3. Set the interface description. Optional. By default, the description of an interface is in the format of interface-name Interface. For example, Ethernet1/1 Interface. description text Optional. By default, the duplex mode is auto for an Ethernet interface. Set the duplex mode of the interface. duplex { auto | full | half } 5. Set the port speed.
You might need to shut down and then bring up an Ethernet interface or subinterface to activate some configuration changes, for example, the speed or duplex mode changes. To shut down an Ethernet interface or subinterface: Step 1. Enter system view. Command Remarks system-view N/A • Enter Ethernet interface view: interface interface-type interface-number 2. Enter Ethernet interface or subinterface view, or port group view. Use one of the commands.
Configuring physical state change suppression on an Ethernet interface No Available only on Layer 3 GE interfaces No No Available only on Layer 3 GE interfaces Available only on Layer 3 GE interfaces No The physical link state of an Ethernet interface is either up or down.
Step Command Remarks 1. Enter system view. system-view N/A 2. Enter Ethernet interface view. interface interface-type interface-number N/A 3. Enable loopback testing. loopback { external | internal } By default, loopback testing is disabled.
To set the statistics polling interval globally: Step Command Remarks 1. Enter system view. system-view N/A 2. Set the statistics polling interval globally. flow-interval interval Optional. Configuring a Layer 2 Ethernet interface Configuring a port group Some interfaces on your device might use the same set of settings. To configure these interfaces in bulk rather than one by one, you can assign them to a port group. You create port groups manually.
If you set a traffic suppression threshold for an Ethernet interface that belongs to a port group in both Ethernet interface view and port group view, the threshold configured last takes effect. MSR93X routers do not support multicast storm suppression. To set storm suppression thresholds on one or multiple Ethernet interfaces: Step 1. Enter system view. Command Remarks system-view N/A • Enter Ethernet interface view: 2. Enter Ethernet interface view or port group view.
Step 1. 2. Enter system view. Configure jumbo frame support. Command Remarks system-view N/A jumboframe enable [ value ] By default, the device allows jumbo frames within the specified length to pass through all Layer 2 Ethernet interfaces. The maximum length of jumbo frames allowed to pass through depends on your device model. Support for the value argument depends on your device model. If you set the value argument multiple times, the latest configuration takes effect.
when a loop is detected, for example, to shut down the interface. When no protective action is configured, the device takes the actions in Table 1 to alleviate the impact of the loop condition. Table 1 Actions to take upon detection of a loop condition Port type Actions when no protective action is configured • Place the receiving interface in controlled mode. The interface discards all Access port incoming packets, but still forwards outgoing packets. • Generate traps.
Step Command Enable loopback detection in all the VLANs on the trunk or hybrid port. 7. Remarks Optional. loopback-detection per-vlan enable By default, a trunk or hybrid port performs loopback detection only in its PVID. Setting the MDI mode of an Ethernet interface IMPORTANT: Fiber ports do not support the MDI mode setting. You can use both crossover and straight-through Ethernet cables to connect copper Ethernet interfaces.
Testing the cable connection of an Ethernet interface IMPORTANT: • Fiber ports do not support this feature. • If the link of an Ethernet port is up, testing its cable connection will cause the link to come down and then go up.
Configuring a Layer 3 Ethernet interface or subinterface Setting the MTU for an Ethernet interface or subinterface The value of Maximum Transmission Unit (MTU) affects the fragmentation and re-assembly of IP packets. To set the MTU for an Ethernet interface or subinterface: Step Command Remarks 1. Enter system view. system-view N/A 2. Enter Ethernet interface or subinterface view. interface interface-type { interface-number | interface-number.subnumber } N/A 3. Set the MTU.
To configure a different MAC address for a specific Layer 3 Ethernet subinterface, you can use the mac-address command. HP recommends not configuring a MAC address in the VRRP-reserved MAC address range for a Layer 3 Ethernet subinterface. To configure the MAC address of an Ethernet interface or subinterface: Step Command Remarks 1. Enter system view. system-view N/A 2. Enter Ethernet interface view. interface interface-type { interface-number | interface-number.
Step Command Remarks 2. Enter Ethernet interface view. interface interface-type interface-number N/A 3.

Set alarm thresholds. ft1 alarm-threshold { ais { level-1 | level-2 } | lfa { level-1 | level-2 | level-3 | level-4 } | los { pulse-detection | pulse-recovery } value } pulse-detection is 176 and the threshold of pulse-recovery is 22. If the number of the pulses detected during the total length of 176 pulse detection intervals is smaller than 22, the pulse-recovery threshold, a LOS alarm occurs.
The local end sends out a pattern, which is to be looped over somewhere on the line and back to the local end. The local end then checks the received pattern for the bit error rate, and by so doing helps you determine whether the condition of the line is good. To this end, you must configure loopback to allow the transmitted pattern to loop back from somewhere on the line, for example, from the far-end interface by placing the interface in far-end loopback.
When the E1 line is operating in framed (CE1) mode, you can bundle timeslots on it. The system automatically creates a serial interface numbered serial number/line-number:set-number for it. This interface operates at N × 64 kbps and is logically equivalent to a synchronous serial interface where you can make other configurations.

Overview ADSL technologies Asymmetric Digital Subscriber Line (ADSL) is an asymmetric transmission technology that implements high-speed data transmission over twisted-pair copper wire by using unused high frequency ranges in the regular telephone line with a different modulation method. With standard ADSL, the band from 26 kHz to 138 kHz is used for upstream communication, while 138 kHz to 1.104 MHz is used for downstream communication.
is set up between the two parties. When negotiating connection parameters during the line activation, the CO equipment provide and decide values for most parameters, while the CPE accept them. Contrary to activation, deactivation tears down the communication connection between the two parties. The router tests the performance of the line regularly. Once it finds out that the line performance is deteriorating, it automatically deactivates, retrains, and reactivates the line.

Figure 11 STM-N frame structure STM-N is a rectangle-block frame structure of 9 rows x 270 x N columns, where the N in STM-N equals the N columns. N takes the value 1, 4, 16, and so on, indicating the number of STM-1 signals that form SDH signal. The STM-N frame structure consists of three parts: the section overhead (SOH), which includes the regenerator section overhead (RSOH) and the multiplex section overhead (MSOH); the administration unit pointer (AU-PTR); and payload.

• The physical state of the interface is UP, but the link protocol is DOWN. • The serial interface is in a looped condition, even though loopback detection is not configured on the interface. Solution The symptom might occur when the router and its directly connected SDH device have different multiplex paths for the E1 channels. Multiplex path inconsistency can cause PPP negotiation failure because the SDH device transmits signals from the router in incorrect timeslots to the remote end.
Configuring loopback and null interfaces Configuring a loopback interface Introduction A loopback interface is a virtual interface. The physical layer state and link layer protocols of a loopback interface are always up unless the loopback interface is manually shut down. A loopback interface is widely used in the following scenarios: A loopback interface address can be configured as the source address of the IP packets that the device generates.
You can configure settings such as IP addresses and IP routes on loopback interfaces. For more information, see Layer 3—IP Services Configuration Guide and Layer 3—IP Routing Configuration Guide. Configuring the null interface Introduction A null interface is a completely software-based logical interface, and is always up. However, you cannot use it to forward data packets or configure an IP address or link layer protocol on it.
