Column Meaning
Broadcast Packets
Received
The total number of packets received that were directed to the broadcast address.
Note that this does not include multicast packets.
Receive Packets
Discarded
The number of inbound packets which were chosen to be discarded even though no
errors had been detected to prevent their being deliverable to a higher-layer protocol.
One possible reason for discarding such a packet could be to free up buer space.
Packets Transmitted
Without Error
The total number of packets transmitted out of the LAG.
Transmit Packets
Discarded
The number of outbound packets which were chosen to be discarded even though no
errors had been detected to prevent their being deliverable to a higher-layer protocol.
A possible reason for discarding a packet could be to free up buer space.
Transmit Packets Errors The number of outbound packets that could not be transmitted because of errors.
Collisions Frames The best estimate of the total number of collisions on this Ethernet segment.
Time Since Counters Last
Cleared
The elapsed time, in days, hours, minutes, and seconds since the statistics for this LAG
were last cleared.
show fiber-ports optical-transceiver
This command displays the diagnostics information of the SFP like Temp, Voltage, Current, Input Power,
Output Power, Tx Fault, and LOS. The values are derived from the SFP's A2 (Diagnostics) table using the
IC interface.
Format
show fiber-ports optical-transceiver {all | unit/slot/port}
Mode Privileged EXEC
Column Meaning
Temp Internally measured transceiver temperature.
Voltage Internally measured supply voltage.
Current Measured TX bias current.
Output Power Measured optical output power relative to 1mW.
Input Power Measured optical power received relative to 1mW.
TX Fault Transmitter fault.
LOS Loss of signal.
