LAG X690 between SFP and UTP

[Elena_Madrigal]

Hello i have a Stack between two switch model X690 one of then 10G fiber an other of copper switch. But when i make a lag show the following error. It is possible to make a lag between 10G copper +10 G fibber?

Anybody know if its possible to make a LAG betweem 10g fiber and 10g copper? or could be a bug.?

GTAC solution
After looking into this i have found that it is not possible to create a lag with mixed UTP and fiber ports.

Auto-negotiation is mandatory for 10GbBase-T according to the 802.3 standard, while it’s not possible on fiber due to the possible different wavelengths of light and different signal timing in the various types of transceivers.

Unfortunately there is no way around this.

It not possible by the moment

You can try bypass this. If you put base-t tranciever into SFP+ slot then x690 will change autonegotiation to ON and spped to 1000. Then you can try to add port to sharing.

I did something similar yesterday. Before inserting tranciever:

2:46     VR-Default E       R   OFF 10000       FULL                    NONE

after inserting:

2:46     VR-Default E       R    ON  1000       AUTO              1:47  1000T

No ten gig, 40 gig, or 100 gig interface should have auto negotiation on... Standard is off You should set them both to off not on .. this will allow your lag to complete.
