port Suggested Actions, General
Some specific examples are displayed below, but in general, use the following CLI commands to check
for these conditions:
For port SFP errors, use commands such as showport, showport -sfp, and showport -sfp -ddm.

Component -Identifier- --Detailed Description--
Port port:0:1:1 SFP is Degraded
port Suggested Action 1
An SFP in a Node-Port is reporting a degraded condition. This is most often caused by the SFP receiver
circuit detecting a low signal level (RX Power Low), and that is usually caused by a poor or contaminated
FC connection, such as a cable. An alert should identify the condition, such as the following:
Port 0:1:1, SFP Degraded (Receiver Power Low: Check FC Cable)
Check SFP statistics using CLI commands, such as showport -sfp, showport -sfp -ddm.

In the following example an RX power level of 522 microwatts (uW) for Port 0:1:1 DDM is a good reading;
and 12 uW for Port 1:1:1 is a weak reading ( < 15 uW). Normal RX power level readings are 300-700 uW.
