In the following example an RX power level of 361 microwatts (uW) for Port 0:0:1 DDM is a good
reading; and 98 uW for Port 0:0:2 is a weak reading (< 100 uW). Normal RX power level
readings are 200-400 uW.

Port port:0:3:1 SFP is missing
Port Suggested Action 2
FC node-ports that normally contain SFPs will report an error if the SFP has been removed. The
condition can be checked using the showport -sfp command. In this example, the SFP in 0:3:1
has been removed from the adapter:
