hi everyone
I have SFP+ cables which seems to work fine but on one(maybe more?) port(Te 2/0/27) I see "unqualified transceiver" and port gets put down administratively.
Now, next door ports, eg 25 or 29 do not do that, I think I got "unqualified" transceiver but port stay up/online.
Is this not weird? Why switch would be doing this?
nos 7.2.0a1
many thanks, L.

I think it might have had something to do with a node used "broadcast" instead of LACP.
I think that because whichever switch ports I connected the node to those ports would go adminDown after a short wile.
I'll take more time to find if that was the root cause.
(node being Centos with net team device spanning two SPF+ ports(dual port NIC))
Would/should switch behave this way is such a situation?

HI L,
If its unsupported transceiver, then it wasn't tested by Extreme, behavior might be unpredictable.
