show interface sfp diagnostic—Display SFP diagnostic information for fiber-based SFPs only (on vEdge routers only). This data is taken from bytes in the SFP A2 page, as described in SFF-8472. This section is not available for copper RJ45 SFPs.
The data for this output is stored in the A2 page of the SFP, and it contains minimum/maximum threshold parameters for laser transmitters and receivers, as well as dynamic run-time data values. This data page also might contain calibration data if the devices were externally calibrated. In this show command, the calibration data is used, if populated; however, it is not specifically be displayed.
show interface sfp diagnostic [interface-name]
- Display SFP diagnostic information for all interfaces in the router.
- Interface Name
Display SFP diagnostic information for the specific interface.
The following information is displayed for SFP diagnostics. Measurement information is presented as floating-point data.
Threshold and measurement data are all floating point data and are specified for accuracy relative to the source data. Measurement units are included in the value label.
In addition to allowing current measurements to be display, each of the following measurements has associated flag status indicating whether the measurement is in or out of alarm or warning state. This data is sourced from A2.112-117 SFP data.
Based on options declared to be supported by the SFP, several bit-based statuses are included in the display output. These include items such as select, transmit disable state, and receive loss-of-signal state, and are from A2.110.
