[f-nsp] SFP-T in XMR

[Jorik Jonker]

Hi all,

Ronald's story seems very accurate: I based my conclusions on 5 "non-working" SFP's out of a batch of 13. I just plugged in the other 8, and guess what:

3/1   Down None      None None
3/2   Up   Forward   Full 1G  
3/3   Up   Forward   Full 1G  
3/4   Up   Forward   Full 1G  
3/5   Up   Forward   Full 1G  
3/6   Up   Forward   Full 1G  
3/7   Up   Forward   Full 1G  
3/8   Up   Forward   Full 1G  
3/9   Up   Forward   Full 1G  
3/10  Down None      None None
3/11  Down None      None None
3/12  Down None      None None
3/13  Down None      None None

3/1, 3/10-3/13 are the 5 I've tested before mailing f-nsp. What are the odds? Since I'll be needing only 4 SFP's in the first stage of this customer installation I'll be sending back the 5 bad ones accompanied with a proper one and a not "please make these into this one".

Thanks for the e-mails, since they triggered me in testing them all.

Jorik,

Chances are, since you're using a third party SFP, that it doesn't match for the XMR. We've had recently 4 different SFP's (E1MG-TX) programmed for Brocade devices of which only 1 worked in a MLX, while all 4 worked on a FESX.

Rgds,

> Some further info: the SFP-T/E1MG-TX is not an official Brocade one, but one from a third party (SmartOptics), which has specifically programmed it for use in a Brocade device. We have extended experience with this particular vendor producing quality OEM but brand-recognized optics.

> Of course there is a small chance that we have a wrong (set of) optic(s), but the fact that a RX4 is happy with it suggests me that we have to trick the XMR into something.

> The "other side", in this case a laptop, HP switch, FESX424 or whatever 1G RJ45 capable device thinks it has link up (Full 1G) while the XMR holding the SFP still has link down. When I put this SFP into a RX-BI-24F in a RX, both sides have 1G full link up. When I use a different XMR or a different board I get the same situation.
