Exactly this, get your unlock key that is tied to your company and you are off to the races, bake it into your standard 
config.  Your SE or support team should be able to get this to you :)

Yes, email support and ask for the unlock code, they will make you agree that you know that 3rd party optics may 
explode the switch and it's not their fault.


The command they give you will have a key/hash built into it (but will work on any switch) that ties the "unlock" to 
your org.


Ours looks like this:

Hi all,
Is there a way for unlocking off-brand transceivers usage on Arista switches?

I've got an Arista 7050QX switch with 4.14 EOS version. Then it has been found out that Arista switches seem to not 
have possibility to unlock off-brand xcievers usage (by some service command or so).

I've patched /usr/lib/python2.7/site-packages/XcvrAgent.py, made the checking function bypass the actual check and it 
helped: ports are not in errdisable state anymore. But despite of xceivers are detected correctly, links aren't coming 
up (they are in notconnect state).

If anyone possibly have does have a sacred knowledge of bringing off-branded transceivers to life on Arista switches, 
your help'd be very appreciated. Thanks.
