**Table 1** Description of the **display wan interface** command output
Item	Description
current state	Physical status of the interface. UP. DOWN. Administratively Down: The administrator has run the shutdown command on the interface.
Line protocol current state	Link protocol status of the interface: UP: The link protocol is enabled and works normally. DOWN: The link protocol does not work properly or no IP address is assigned to the interface.
Physical layer is	Information about the link at the physical layer. The physical layer of the WAN GE interface is Packet over SDH.
SDH OverHead	Information about SDH overhead bytes.
SDH alarm	sdh alarm.
Scramble	Scrambling is disabled or enabled.
WAN full-duplex mode	The working mode is full-duplex.
WAN Alarm	wan alarm.
Pause Flowcontrol	Whether pause frames are used to perform flow control.
section layer	Regenerator section. B1 represents the number of error packets after parity check is inserted among bits. The parity check checks the bit errors during the STM-N frame transmission.
line layer	Multiplex section information. B2 represents the bytes of BIP-N x 24 bits, which is used to monitor the bit errors during each STM-1 frame transmission in the bit interleaved parity check. REI (Remote Error Indication) represents the indication of a remote error.
path layer	Path information. B3 byte monitors the bit errors of VC4 in STM-N frames. The monitoring principle is similar to B1 and B2. The difference is that B3 performs the BIP-8 check for VC4 frames.
Last 300 seconds input rate Last 300 seconds output rate	Rate of the received and sent bytes and packets within last 300 seconds.
Undersized Frame	Number of packets whose frame length is smaller than the lower limit and can be normally transmitted.
Transceiver max BW	transceiver max bw.
Rx	Value of various overhead bytes when the interface acts as the receiver.
Tx	Value of various overhead bytes when the interface acts as the transmitter.
Clock	Master or slave clock mode.
CRC-32	32-bit CRC is used.
Loopback	The loopback mode is internal, external, or disabled.
Input	Number of all received packets and bytes.
Output	Number of all sent packets and bytes.
Unicast	Number of sent or received unicast packets.
Multicast	Number of sent or received multicast packets.
Broadcast	Number of sent or received broadcast packets.
JumboOctets	Number of sent or received jumbo frames (greater than 1518 bytes).
CRC	Number of packets that are normal in length but fail the CRC check.
Symbol	Number of packets that are normal in length but have data receiving failures or incorrect data symbols at the physical layer.
Overrun	Number of packets that fail to be processed because the interface receives packets at a speed higher than the forwarding speed.
InRangeLength	Number of packets in which the value of the length/type field is reasonable but inconsistent with the actual packet length and in which the value of the length/type field is smaller than the minimum frame length.
LongPacket	Number of packets whose frame length is greater than 9618 bytes and can be normally transmitted.
Jabber	Number of packets whose frame length is greater than 9618 bytes and have CRC errors.
Fragment	Number of packets whose frame length is smaller than the lower limit and have CRC errors.
RxPause	Number of received pause frames.
TxPause	Value of various overhead bytes when the interface acts as the transmitter.
WaveLength	WaveLength.
sdh error	sdh error.
System	system.
