the following:

Port 0:0:2, SFP Degraded (Receiver Power Low: Check FC Cable)

Check SFP statistics using CLI commands such as

showport -sfp -ddm

showcage

, etc.

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’s is a weak reading ( < 100 uW). Normal RX power level

readings are 200-400 uW.
