The display interface phy-option command can view the physical features of a specified interface.
The actual command output varies according to the device. The command output here is only an example.
<HUAWEI> display interface phy-option gigabitethernet 0/1/0 GigabitEthernet0/1/0 Port Physical Status : DOWN Physical Down Reason : transceiver offline Loopback : none Duplex mode : full-duplex negotiation : disable Pause Flowcontrol : Receive Enable and Send Disable SFP information: Optical transceiver is offline!

| Item | Description |
|---|---|
| Port Physical Status | Physical link status of an interface.
|
| Physical layer | Physical link. |
| Physical Down Reason | Indicates the reason why the physical link of the interface goes Down. |
| Scramble | Scrambling function is enabled. |
| Clock | Clock mode. |
| CRC | Number packets that fail the CRC. |
| Loopback | Whether loopback is enabled. The options are as follows:
|
| Flag J0 | Value of the J0 overhead byte. |
| Flag J1 | Value of the J1 overhead byte. |
| Flag C2 | Value of the C2 overhead byte. |
| Optical information | Basic information about the optical module. |
| transceiver max bw | Maximum bandwidth of the optical module. |
| Transmission-alarm delay(holdup-timer) | Delay for clearing an alarm. If alarm clearance messages are received within a filtering interval set using the transmission-alarm holdup-timer command, the alarm clearance messages are filtered. An alarm is cleared only when an alarm clearance message is received after the filtering interval expires. |
| Transmission-alarm delay(holdoff-timer) | Delay for generating an alarm. If alarm generation messages are received within a filtering interval set using the transmission-alarm holdoff-timer command, the alarm generation messages are filtered. An alarm is generated only when an alarm generation message is received after the filtering interval expires. |
| FEC Mode | Forward error correction (FEC) mode:
|
| FEC information | FEC bit error ratio detection information. |
| OTU TTI | TTI of the received OUT. |
| ODU TTI | TTI of the received ODU. |
| Duplex mode | Duplex mode (full-duplex mode full-duplex; Half-duplex mode half-duplex).
|
| negotiation | Whether auto-negotiation is enabled. |
| Pause Flowcontrol | Whether Ethernet flow control frames are enabled.
|
| SFP information | Indicates the basic information about an optical module. |
| Carrier delay(up-hold-time) | Run the carrier up-hold-time command to set the delay time for the interface to go Up when the interface status changes from Down to Up. Otherwise, the default time is displayed. |
| Carrier delay(down-hold-time) | Run the carrier down-hold-time command to set the delay time for the interface to go Down when the interface status changes from Up to Down. Otherwise, the default time is displayed. |
| connector type | connector type. |
| wavelength | Wavelength. |
| rx power | Receive power. |
| receive | Receive. |
| factor/module | Module Type. |
| tx power | Transmit Power. |
| rx warning range | Alarm range of the receive power of the optical module. |
| port bw | Port Bandwidth. |
| send | Send. |
