Displays information about the transceivers. If a port is specified, displays information for the transceiver in that port. The hpicfTransceiver MIB is available for displaying transceiver information. The transceiver information displayed depends on the show command executed. The output for show interfaces transceiver [ port-list ] is shown below. You can specify multiple ports, separated by commas, and the information for each transceiver will display.
If there is no transceiver in the port specified in the command, the output displays as shown below. When no ports are specified, information for all transceivers found is displayed. You can specify all for port-list as shown below. When the show interfaces transceiver [port-list] detail command is executed, the following information displays.
An Example: of the output for the show interfaces transceiver [port-list] detail for a SX transceiver is shown below. This feature provides the ability to view diagnostic monitoring information for copper transceivers with Virtual Cable Test VCT support. The cable quality of the copper cables connected between transceivers can be ascertained using the transceiver cable diagnostics. Enter the test cable-diagnostics command in any context to begin cable diagnostics for the transceiver.
The diagnostic attempts to identify cable faults. The tests may take a few seconds to complete for each interface. There is the potential of link loss during the diagnostic.
Viewing transceiver information. Alarm flags associated with power supply voltage indicate conditions likely, but not necessarily, to be associated with an operational failure of the transceiver and cause for immediate action. Displays whether the module voltage low alarm is On or Off. Displays whether the module voltage high warning is On or Off. Warning flags associated with power supply voltage indicate conditions outside the normal limits; however, that need not cause immediate link failures.
Displays whether the module voltage low warning is On or Off. Displays whether the receive laser power high alarm is On or Off. Transceivers generate monitoring data such as receive optical power by digitization of internal analog signals.
Alarm flags associated with receive optical power indicate conditions likely, but not necessarily, to be associated with an operational failure of the transceiver and cause for immediate action.
Displays whether the receive laser power low alarm is On or Off. Displays whether the receive laser power high warning is On or Off.
Warning flags associated with receive optical power indicate conditions outside the normal limits; however, that need not cause immediate link failures. Displays whether the receive laser power low warning is On or Off. Displays whether the module not ready alarm is On or Off.
When the output is On , the module has an operational fault. Displays whether the module low power alarm is On or Off. The host may use the module power mode to limit module power consumption to one of two thresholds—low power mode or high power mode. When operating in low power mode, the maximum power consumption of the module will remain below a defined maximum.
Active module functionality is limited to host-to-module interactions over the management interface. Passive copper cable assemblies may operate in low power mode at all times and are fully functional. Displays whether the module initialization incomplete alarm is On or Off. Displays whether the module fault alarm is On or Off.
This alarm is generated when the transceiver module detects a condition such as TEC runaway or flash corruption that could cause damage to the module. This alarm is provided as a notification to the host that a module fault has occurred.
The implementation of the module fault is form factor dependent. This alarm is generated if the initialization of transceiver module internal programmable logic device PLD or flash device fails. Displays whether the power supply fault alarm is On or Off.
Displays whether the checksum fault alarm is On or Off. To protect against degradation in the non-volatile storage and potential errors in transfer, the module management interface defines a few registers to let module manufacturers save checksums or check codes. Each checksum or check code is assigned for a small-sized datum derived from a block of digital data.
The algorithms of calculation for checksums or check codes are defined by management interface specifications of form factors. For example, the checksum or check code shall be the low order 8 bits of the sum of the contents of that small-sized datum.
Prior to using the stored information, module users calculate the checksums or check codes again using the same algorithm. If the results are different from those saved in checksum bytes by module manufacturers, checksum fault alarm is triggered.
A Checksum fault means that the content of the small-sized datum covered by this checksum is corrupted or changed. Displays whether the Tx laser disabled alarm is On or Off. Displays whether the module power down alarm is On or Off. When the output is On , module is in a limited power mode, low for normal operation. Any condition leading to invalid data on the transmit path. Displays whether the Tx data not ready alarm is On or Off. Displays whether the Tx not ready alarm is On or Off.
Laser fault condition. Displays whether the Tx laser fault alarm is On or Off. Transmit clock and data recovery CDR loss of lock. Loss of lock on the transmit side of the CDR. The CDR has its own oscillator and uses a phase locked loop PLL to calibrate the oscillator and match it to the phase and frequency of the incoming signal.
The feedback circuit of PLL eventually locks the local oscillator on to the phase and frequency of the incoming signal. The PLL maintains that lock by continuously monitoring the received signal. Any condition leading to invalid data on the receive path. Displays whether the Rx not ready alarm is On or Off. Receive loss of signal alarm. When the output is On , indicates insufficient optical input power to the module.
Displays whether the Rx loss of signal alarm is On or Off. Receive CDR loss of lock. Loss of lock on the receive side of the CDR. Displays the vendor-specified threshold for the laser temperature high alarm, in Celsius and Fahrenheit. Displays the vendor-specified threshold for the laser temperature low alarm, in Celsius and Fahrenheit.
Displays the vendor-specified threshold for the laser temperature high warning, in Celsius and Fahrenheit. Displays the vendor-specified threshold for the laser temperature low warning, in Celsius and Fahrenheit.
Displays whether the laser receiver power high alarm is On or Off. This alarm is triggered when the receive optical power is higher than the high alarm threshold. Displays whether the laser receiver power low alarm is On or Off. This alarm is triggered when the receive optical power is lower than the high alarm threshold. Displays whether the laser receiver power high warning is On or Off. This warning is triggered when the receive optical power is higher than the high warning threshold.
Displays whether the laser receiver power low warning is On or Off. This warning is triggered when the receive optical power is lower than the high warning threshold.
Displays the laser receiver power, in milliwatts mW and decibels referred to 1. Displays whether the Tx loss of signal functionality alarm is On or Off. This alarm is generated if the high-speed electrical signal amplitude of Tx input is below a threshold. APD requires a bias voltage. If there is a disruption in the bias voltage supply, the APD supply fault alarm is generated. Displays whether the Wavelength unlocked alarm is On or Off.
The transmitter wavelengths of some transceivers must be maintained at greater accuracy over operational lifetimes. Wavelength locker is used to stabilize the wavelength of the laser diode.
If the wavelength is out of the specified range, the wavelength unlocked alarm is generated. Help us improve your experience. Let us know what you think. Do you have time for a two-minute survey?
