mode), and others can operate as either Layer 2 or Layer 3 Ethernet interfaces (you can set the link mode to bridge or route). After you change the link mode of an Ethernet interface, all settings are restored to their default values in the new link mode. Examples # Configure Ethernet 1/1 to operate in Layer 2 mode.
Usage guidelines Depending on the hardware structure of interface cards, some interfaces can operate only as Layer 2 Ethernet interfaces (in bridge mode), some can operate only as Layer 3 Ethernet interfaces (in route mode), and others can operate as either Layer 2 or Layer 3 Ethernet interfaces (you can set the link mode to bridge or route). Configuring the port link-mode interface-list command in system view and configuring the port link-mode command in Ethernet interface view lead to the same result.

Views Layer 2 Ethernet interface view, port group view Default command level 2: System level Parameters ratio: Sets the unknown unicast suppression threshold as a percentage of the maximum interface rate. The value range is 1 to 100.
virtual-cable-test Use virtual-cable-test to test the cable connection of an Ethernet interface. The test results are displayed within 5 seconds.
If the cable connection is normal, the displayed cable length is the total length of the cable. If the cable connection has a fault, the displayed cable length is the length from the local port to the faulty point. Fiber ports do not support this command. If the link of an Ethernet interface is up, testing its cable connection will cause the link to go down and then up. The test result is for reference only. The cable length detection error is up to 5 m (about 16 ft).
Default command level 2: System level Parameters mac-address: Specifies a MAC address, in the format of H-H-H. Usage guidelines When you configure the MAC address of a Layer 3 Ethernet subinterface with the mac-address command, select a MAC address different from that of the host interface. HP recommends not configuring a MAC address in the VRRP-reserved MAC address range for a Layer 3 Ethernet subinterface.
Examples # Enable Layer 3 VE interface Virtual-Ethernet 1 to check the destination MAC addresses of incoming IP packets. system-view [Sysname] interface Virtual-Ethernet 1 [Sysname-Virtual-Ethernet1] mac-address valid-check enable mtu Use mtu to set the MTU for an Ethernet interface or subinterface.

The default timeout time is 2000 milliseconds. interface type number: Specifies an interface. Usage guidelines Use looptest to detect loops on interfaces. The system returns the following line quality information: • Information about each test packet. If a test packet is looped back, the number of bytes, sequence number, and delay are displayed for the test packet.
Default No PRI set is created. Views CT1/PRI interface view Default command level 2: System level Parameters list: Specifies timeslots to be bundled. Timeslots are numbered 1 through 24. You can specify a single timeslot by specifying a number, a range of timeslots by specifying a range in the form of number1-number2, or several discrete timeslots by specifying number1, number2-number3.
The reset counters interface command clears the counters of all interfaces. To clear the controller counter of individual CT1/PRI interfaces, use the reset counters controller t1 command. Examples # Clear the controller counter for CT1/PRI interface T1 2/0. reset counters controller t1 2/0 sendloopcode Use sendloopcode to send remote loopback control code.
Use this command in conjunction with the far-end T1 device. The far-end device must be able to set loopback mode depending on the detected loopback code. The sending of remote loopback control code lasts five minutes without affecting the operation of other interfaces. Examples # Send in-band LLB activation request code.

Syntax e1 line-number shutdown undo e1 line-number shutdown Default E1 lines are up. Views CE3 interface view Default command level 2: System level Parameters line-number: E1 line number in the range of 1 to 16. Usage guidelines This command affects not only the specified E1 line but also the serial interfaces formed by E1 line bundling.
Parameters line-number: E1 line number in the range of 1 to 16. Usage guidelines An E1 line in unframed mode does not contain the frame control information; it cannot be divided into timeslots. The system automatically creates a serial interface numbered serial number/line-number:0 for it. This interface operates at 2048 kbps and is logically equivalent to a synchronous serial interface on which you can make other configurations.
Usage guidelines FE3 mode is a non-standard E3 application mode. In this mode, the subrate level setting varies with vendors. You can use the fe3 command to make the device to be compatible with devices of other vendors operating in specific FE3 DSU modes. This command is only applicable to CE3 modules that support FE3. This command is available only in E3 mode. As for the fe3 subrate command, the actual subrate usually is not exactly the one set by the command.
Usage guidelines Loopback is intended for test use. Disable loopback in other cases. If a CE3 interface encapsulated with PPP is placed in a loopback, it is normal that the state of the link layer protocol is reported as down. Examples # Enable internal loopback on interface E3 2/0. system-view [Sysname] controller e3 2/0 [Sysname-E3 2/0] loopback local national-bit Use national-bit to configure the national bit on the CE3 interface. Use undo national-bit to restore the default.

Usage guidelines You can use the display controller e3 command to display the statistics collected by the controller counters of CE3 interfaces. The reset counters interface command clears the counters of all interfaces. To clear the controller counter of individual CE3 interfaces, use the reset counters controller e3 command.
Examples # Configure interface E3 2/0 to operate in unchannelized mode. system-view [Sysname] controller e3 2/0 [Sysname-E3 2/0] using e3 Related commands controller e3 Basic CT3 interface configuration commands alarm (CT3 interface) Use alarm to enable the CT3 interface to detect/send alarm signals. Use undo alarm to remove the alarm signal detection/sending setting.
when the RAI signal generated upon detection of the LOS, LOF, or AIS signal is present, the CT3 interface cannot send another type of signal. To do that, use the undo alarm detect command to disable the CT3 interface from sending the RAI signal generated upon detecting an alarm first. You can view the alarm state information by using the display controller t3 command. Examples # Enable periodical alarm signal detection on CT3 interface T3 2/0.
When running a BERT test, 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 examines the received pattern for bit error rate to help you identify whether the condition of the line is good. 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.
Syntax clock { master | slave } undo clock Default The clock source for the CT3 interface is line clock. Views CT3 interface view Default command level 2: System level Parameters master: Adopts the internal clock as the clock source. slave: Adopts the line clock as the clock source.
