Switchs displaying old SFP

Question

Hi all,

I have replaced LW SFP operating at 2 Gb/s with LW SFP operating at 4 Gb/s.
ISLs have been succesfully changed from 2 Gb/s to 4 Gb/s but I still see old SFPs with sfpshow command. I have not rebooted my Brocade switchs, I can't as they are in production.

I have this problem on 3 switchs. On a fourth switch there is no problem, sfpshow shows the new SFP. I guess there is a problem with a daemon missing on the switchs or something like that...

Switchs are Silkworm 4900 with Fabric OS v5.1.0a.

have you tried disabling and enabling changed ports?

ovivier · Answer

Yes I have tried.

A bit more details : I have 2 ISLs between 2 switchs (ports 23 and 31) and I used this procedure :

1) Launch "portperfshow" on both switchs to display throughput
2) "portdisable 23" on both switchs
3) Disconnect fibres from ports 23
4) Remove 2 Gb/s SFPs and insert 4 Gb/s SFPs on ports 23
5) Connect fibres on ports 23
6) "portenable 23" on both switchs
7) Check throughput with "portperfshow"
8) Repeat steps 2 to 7 for ports 31

could be a code issue...about the switch thats showing correct output, is it same model and code ?

Kiran3 · Answer

ya that seems right (or wrong )

ovivier · Answer

Yes unfortunately there is no difference between the correct switch and the others

What is strange too is that 'sfpshow' shows old characteristics (100,200_MB/s SM lw Long_dist) but 'portshow' show that the SFP speed is 4 Gb/s !That is why I was thinking about a daemon down or something like that.
