Failure to apply a command on one member interface does not affect the application of the command on the other member interfaces. If applying a command on one member interface fails, the system displays an error message and continues with the next member interface. Configuration guidelines When you bulk configure interfaces in interface range view, follow these restrictions and guidelines: • In interface range view, only the commands supported by the first interface are available.
Displaying and maintaining bulk interface configuration Execute the display command in any view. Task Command Display information about the specified interface range or all existing interface ranges.
Configuring Ethernet interfaces 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 switch packets. • Layer 3 Ethernet interfaces—Physical Ethernet interfaces operating at the network layer (Layer 3) to route packets. You can assign an IP address to a Layer 3 Ethernet interface.
Step Enter Ethernet interface view. 2. Command Remarks interface interface-type interface-number N/A By default, the copper combo port is active. Activate the copper combo port or fiber combo port. 3. combo enable { copper | fiber } When the loopback command is running on a combo interface, you cannot use the combo enable command on the combo interface.
Configuring the link mode of an Ethernet interface CAUTION: After you change the link mode of an Ethernet interface, all commands (except the shutdown command) on the Ethernet interface are restored to their defaults in the new link mode. Ethernet interfaces of the device can operate either as Layer 2 or Layer 3 Ethernet interfaces (you can set the link mode to bridge or route). To change the link mode of an Ethernet interface: Step Command Remarks 1. Enter system view. system-view N/A 2.
Performing an internal loopback test on an Ethernet interface If an Ethernet interface does not work correctly, you can perform an internal loopback test on it to test all on-chip functions related to the interface. An Ethernet interface in a loopback test does not forward data traffic. Configuration restrictions and guidelines • On an administratively shut down interface (displayed as in ADM or Administratively DOWN state), you cannot perform an internal loopback test.
Setting the statistics polling interval Step Command Remarks 1. Enter system view. system-view N/A 2. Set the statistics polling interval. flow-interval interval By default, the interface statistics polling interval is 300 seconds. To display the interface statistics collected in the last polling interval, use the display interface command. To clear interface statistics, use the reset counters interface command.
Setting the MDIX mode of an Ethernet interface IMPORTANT: Fiber ports do not support the MDIX mode setting. A physical Ethernet interface comprises eight pins, each of which plays a dedicated role. For example, pins 1 and 2 transmit signals, and pins 3 and 6 receive signals. You can use both crossover and straight-through Ethernet cables to connect copper Ethernet interfaces.
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. mtu size The default setting is 1500 bytes. Configuring the MAC address of an Ethernet interface or subinterface In a network, when the Layer 3 Ethernet interfaces or subinterfaces of different devices have the same MAC address, the devices might fail to communicate correctly.
Task Command Display traffic rate statistics of interfaces in up state over the last sampling interval. display counters rate { inbound | outbound } interface [ interface-type [ interface-number | interface-number.subnumber ] ] Display the operational and status information of the specified interface or all interfaces. display interface [ interface-type [ interface-number | interface-number.subnumber ] ] Display summary information about the specified interface or all interfaces.
Configuring WAN interfaces This chapter describes how to configure interfaces for connecting to WAN networks, including ATM and ISDN.

timeslot bundling. Its logical features are the same as those of a synchronous serial interface. It supports link layer protocols such as PPP, HDLC, FR, LAPB, and X.25, and network protocols such as IP. { When the interface is used as a PRI interface, timeslot 16 will be used as a D channel to transmit signaling. Therefore, rather than selecting among all the timeslots, you are only allowed to make a random B channel selection among the timeslot sets except timeslots 0 and 16.
Step Command Remarks By default, no channel set is created. 4. Bundle timeslots on the interface into a channel set. channel-set set-number timeslot-list list The timeslots on a CE1/PRI interface can be bundled into either channel sets or a PRI set, but not the both, at a time. 5.

Starting/terminating a BERT test on a CT1/PRI interface Bit error rate test (BERT) operates as follows: 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.

Configuring loopback, null, and inloopback interfaces This chapter describes how to configure a loopback interface, a null interface, and an inloopback interface. Configuring a loopback interface A loopback interface is a virtual interface. The physical layer state of a loopback interface is always up unless the loopback interface is manually shut down.
Configuring a null interface A null interface is a virtual interface and is always up, but you can neither use it to forward data packets nor can you configure it with an IP address or link layer protocol. The null interface provides a simpler way to filter packets than ACL. You can filter undesired traffic by transmitting it to a null interface instead of applying an ACL.
Task Command Clear the statistics on the inloopback interface.
