vdx-6740 ports respond differently to the same cable(transceiver)

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.

HI L,

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

Best Regards,

Can you post the show media int te <rbridge-id/slot/port> when the sfp is plugged in the vdx?

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?
