Hi,
Want to flash my Brocade SFP+ FC modules to Cisco vendor id - i try software on CH341 programmer but not success. What tools you use for work with SFP+ modules?

Don't know what you actually want to achieve, but on cisco gear running IOS you can just set
Code:
#service unsupported-transceiver
#no errdisable detect cause gbic-invalid
and use non-cisco transceivers.

The 'unsupported-transceiver' setting is hidden/undocumented, so it won't auto-complete or show up with 'service ?'. If you get a warning message, stating that you are on your own if cisco thinks a third-party transceiver is the cause of your problems, it worked.

Suggests that true OEM require a password or some key before you can write. Gear sold by FS probably doesn't need such a thing.

Thanks, but I'm looking only software to check for compatibility for change vendor id/SN. Ideal would be an open source or ch341 programmer etc.
I started working on something like that some time ago (with full features like also setting Infiniband bits), but haven't finished it yet.


In the meantime, try REVELPROG-IS and the matching QSFP board. It allows you to write arbitrary setups to transceivers (if they're not read only) and also allows you to bruteforce password for locked transceivers
