[c-nsp] Nexus compatible optics

[Jeffrey G. Fitzwater]

I believe I had asked the question about third party optics with the new NX-OS 6.2.2a, and found out that in this revision you MUST enter the command “service unsupported-transceiver” to get them to be recognized.  In previous versions that command was enabled by default.   Who knew!



There were other issues with 6.2.2a which forced us to stay at 6.1.2.

1.  You cannot overwrite an existing file on slot0: even if you have ADMIN privileges…except if you are ADMIN USER.

We are still waiting on resolution and there is a bug ID CSCue23772

They are all private labeled optics by the major manufactures with the correct Cisco SN burned in the EPROM.
