Port 18 does not use an SFP or is disabled
This is the message what I get when I try running this command.
Generally this is the case when port is Disabled (Persistent).
Can you verify by providing switchshow output?
First Steps to troubleshoot :
check hardware : SFP , cable .
Possible I2C bus issue.
Verified port speed .
To bring the port back online, the port needs to be reinitialized to clear the Port_Flt status.
On the disabled port, execute the following two commands:portcfgpersistentdisableportcfgpersistentenable
