SFPSHOW command

sfpshow 18

Port 18 does not use an SFP or is disabled

 

 This is the message what I get when I try running this command.

Re: SFPSHOW command

Hello,

 

Generally this is the case when port is Disabled (Persistent).

Can you verify by providing switchshow output?

Hi ,

 

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:
portcfgpersistentdisable
portcfgpersistentenable

 

Regards

Jerome
