Field Description Link layer state of the interface. The state is determined through parameter negotiation on the link layer. • UP—The interface is up at the data link layer. • UP (spoofing)—The link layer protocol of the interface is UP, but its link is an on-demand link or not present at all. This attribute is typical of Null interfaces and loopback interfaces. • DOWN—The interface is down at the data link layer.
Field Description Unknown-speed mode The speed of the interface is unknown because the speed negotiation fails or the interface is physically disconnected. half-duplex mode The interface is operating in half duplex mode. full-duplex mode The interface is operating in full duplex mode. unknown-duplex mode The duplex mode of the interface is unknown because the duplex mode negotiation fails or the interface is physically disconnected.
Field Description Input(total): 0 packets, 0 bytes Inbound traffic statistics (in packets and bytes) for the interface. All inbound normal and abnormal packets and normal pause frames were counted. 0 unicasts, 0 broadcasts, 0 multicasts, 0 pauses Number of inbound unicast packets, number of inbound broadcasts, number of inbound multicasts, and number of inbound pause frames. A hyphen (-) indicates that the statistical item is not supported.
Field Description Total number of illegal inbound packets: • Fragment frames—CRC error frames shorter than 64 bytes. The length can be an integral or non-integral value. • Jabber frames—CRC error frames greater than the maximum aborts frame length supported on the Ethernet interface (with an integral or non-integral length). For an Ethernet interface that does not permit jumbo frames, jabber frames refer to CRC error frames greater than 1518 bytes (without VLAN tags) or 1522 bytes (with VLAN tags).

This counter increases by one when a carrier is lost, and applies to serial WAN interfaces. no carrier Number of times that the port failed to detect the carrier when attempting to send frames.

Field Description Link layer protocol state of the interface: Protocol • UP—The link layer protocol state of the interface is up. • DOWN—The link layer protocol state of the interface is down. • UP(s)—The link layer protocol state of the interface is up, but the link is an on-demand link or not present at all. This value is typical of interface Null 0 and loopback interfaces.

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, and the Cause field displays DOWN ( Link-Aggregation interface down ).

(Bit 1 is changed into bit 0, and bit 0 changed into bit 1.) After the inversion, at least one bit 1 is present in every eight consecutive bits. When AMI encoding is used on an E1 interface, data inversion eliminates the presence of multiple consecutive zeros. The data inversion setting must be the same on the CE1/PRI interfaces at two ends of an E1 line. Examples # Enable user data inversion on E1 2/3/0.

If you do not specify this argument, the command clears statistics for all CE1/PRI interfaces.
Parameters ce1: Sets the interface to operate in CE1/PRI mode. e1: Sets the interface to operate in E1 mode. Usage guidelines A CE1/PRI interface can operate in either E1 mode (non-channelized mode) or CE1/PRI mode (channelized mode). • In E1 mode, the interface equals a 2.048-Mbps interface without timeslot division and has the same logical features as a synchronous serial interface. • In CE1/PRI mode, the CE1/PRI interface is physically divided into 32 timeslots numbered 0 through 31.
Usage guidelines The CT1/PRI interface supports only the 2^15 and 2^20 BERT patterns defined in ITU O.151, ITU O.153, and ANSI T1.403-1999. To perform a BERT test, the local end sends out a pattern. The pattern is looped over on the line and sent back to the local end. The local end examines the received pattern for bit error rate to help determine the line condition. You must configure loopback to allow the transmitted pattern to loop back from a specific point on the line.

Views System view Predefined user roles network-admin Parameters interface-number: Specifies an ATM interface by its number. interface-number.subnumber: Specifies an ATM subinterface by its number. The interface-number argument represents the number of the ATM interface.
EFM subinterface view Predefined user roles network-admin Parameters size: Specifies the maximum transmission unit (MTU) in the range of 128 to 2000 bytes. Usage guidelines The MTU setting can affect IP packet reassembly and fragmentation on the interface. When you use the mtu command on an interface, execute the shutdown command, and then the undo shutdown command to make your configuration take effect. Examples # Set the MTU of interface ATM 2/4/0 to 200 bytes.
shutdown Use shutdown to shut down an interface. Use undo shutdown to bring up an interface. Syntax shutdown undo shutdown Default An ATM interface is up.

Parameters master: Specifies the internal clock as the clock source. slave: Specifies the line clock as the clock source. Usage guidelines When ATM interfaces are operating as DCEs, set the clock mode to master. When interfaces are operating as DTEs, set the clock mode to slave. When the ATM interfaces on two routers are connected directly through a fiber-optic cable, set the clock mode to master at one end and to slave at the other end. Examples # Set the clock mode of interface ATM 2/4/0 to master.

Syntax loopback { cell | local | remote } undo loopback Default Loopback detection is disabled. Views ATM OC-3c/STM-1 interface view Predefined user roles network-admin Parameters cell: Enables internal cell loopback detection to check physical chips on the local end. local: Enables internal loopback detection to check service chips on the local end.
Usage guidelines With payload scrambling enabled, the interface performs payload scrambling when transmitting data, and payload descrambling when receiving data. Payload scrambling prevents consecutive 0s and 1s in the payload. Disabling payload scrambling disables both payload scrambling during data transmission and payload descrambling during data receiving. Enable or disable payload scrambling on ATM interfaces of both ends for successful interconnection.
During the parameter negotiation process for line activation, typically the CO equipment provides parameters for the CPE. A line activation process starts from line negotiation until the line comes up. Typically the activation process lasts for 30 seconds. Deactivation tears down the connection between the two parties. To transmit services, you must re-activate the interface.
The ADSL interfaces on the two ends must be configured with the same standard. The standard that you specify takes effect when you re-activate the interface by either the shutdown and undo shutdown commands or the activate and undo activate commands. Examples # Apply the standard T1.413 on interface ATM 1/0. system-view [Sysname] interface atm 1/0 [Sysname-ATM1/0] adsl standard t1413 adsl tx-attenuation Use adsl tx-attenuation to set a transmission power attenuation for an ADSL interface.
