So far, we've used the following commands...

service unsupported-transceiver
no errdisable detect cause gbic-invalid

Now it doesn't errdisable, but still goes down/down with the same error as mentioned below.

Have you set the command on the Cisco side to support noncertified transcievers?


Excuse any misspelled words as this is sent from a smart phone.

What type of breakout are you using?

a) QSFP+ to 4xSFP+ ?
b) QSFP+ Transceiver with MTP to 4xLC cable?

I am doing some testing at a customer site with the Z9000 to Cisco 10GB switch.  When we try to use the 40GB to 10GB breakout cable we are getting the following error that disables the ports on the cisco side.

Duplicate vendor-id and serial number

Setup is a two port connection setup in a LAG using LACP.

Is there any known fixes around this issue?  Also there is no issue if you plug in just one of the ports on the 10GB side.

Thanks,
George
