Port Degraded or failed SFPs

Port port:0:1:1
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 must 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.

Port Missing SFPs
Component -Identifier- -Detailed Description--
Port port:0:3:1
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 1:1:1 has been
removed from the Adapter:
