port can't get serial data and Can not read Serial Data!

Good afternoon.
Factory san works, no problem.
But confusing conclusion following commands. (
port  can't get serial data and Can not read Serial Data!)
on those ports that are involved and working in a factory

Please suggest whether this is a mistake or not worth paying attention to it.
Thanks in advance.

Re: port can't get serial data and Can not read Serial Data!

Would you mind giving us the output of a "switchshow" command?

I am suspecting that this is a blade enclosure module, and therefore does not use SFPs for the internal ports.

Re: port can't get serial data and Can not read Serial Data!

On SAN_Switch_2 you should be able to get SFP data for all ports (except port 14). Try with a 'sfpshow PORT -f'.

On SAN_Blade_1 you will only get SFP (serial) data for ports 0, 15, 16, 17 and 18. The other ports will fail with "can't get serial data" since they are direct connected copper ports.

Best regards

Re: port can't get serial data and Can not read Serial Data!

I apologize, but perhaps incorrect syntax


SAN_Switch_2:adm> sfpshow 2  -f

sfpshow: Invalid input parameters

Re: port can't get serial data and Can not read Serial Data!

Hi,

What FOS is running on the switchs? I've seen that behavior in switchs with an old FOS. Upgrade the firmware and let us know if the issue remains.

Rgds,

Felipon

Fabos Version 6.2.2d all switch (4020, E200)


Maximum version that was established when the update on more recent firmware error occurred.

Re: port can't get serial data and Can not read Serial Data!

It seems that "-f" option is not supported in 6.2.2d.

You could try to reseat the SFP and issue the sfpshow afterwards to see if the info is correclty collected.

Re: port can't get serial data and Can not read Serial Data!

Good afternoon.
Once again stood up and pulled the transceiver sfp of each Switch.
Switches began to show 
sfpshow   on  Camondo characteristics transceiver.
Many thanks for the advice.
But the question of why it was necessary to make manipulation of the transceiver? And what problems might occur with transceiver (port can't get serial data and Can not read Serial Data!)?

Re: port can't get serial data and Can not read Serial Data!

Hi,

I suppose that this issue occurs because of the old FOS code. Newer release have added the opetion "-f" that forces the switch to read the SFP prom, but with older releasese, the only way to make the switch read the SFP info is by reseating the SFP.

Usually even though sfpshow does not show the SFP info, the SFP itself works fine.
