display port state(epon)
Function
This command is used to query status information about an EPON port, mainly
the hardware information about the optical transceiver.
Parameters
| Parameter | Description | Value |
|---|---|---|
| portid | Indicates the ID of the EPON port to be queried. | Please see Differences Between Shelves. |
| all | Queries the status of all the ports on an EPON board. | - |
Usage Guidelines
- Run the config command to enter global config mode, and then run the interface epon command to enter EPON mode.
- The threshhold of the transmit optical powe and the threshhold of the bias current are displayed only when the queried PON port is in 10G EPON board.
- For meanings of optical transceiver parameters in this command output, "SFF-8472 Specification for Diagnostic Monitoring Interface for Optical Transceivers" and "XFP-8077i Specification for Diagnostic Monitoring Interface for Optical Transceivers".
