Inter-model stacking

[ehenry24]

Hello,

I've never tried it, but I've always been curious.

Would you be able to stack devices cross chassis - such as 6850-P24 and 2 x 6400-P48's all stacked together?

Thanks,
E

Hi,

OmniSwitch 6400 Series Hardware Users Guide:

Note. Other stackable Alcatel-Lucent products, such as the OmniSwitch 6850, cannot be added to a
stacked OmniSwitch 6400 Series virtual chassis.

And I've also never tried it.

Stacking different families is not supported. If that would be possible, then strange things would happen. A 6850 can do dynamic routing. If the 6850 would fail and the secondary 6400 would take over, then the dynamic routing would be gone (6400 does not support it). Also in a stack the switches synchronize the software version and config. The software from the 6850 is not compatible with the 6400 and vice versa.

I definitely understand the fact that the 6850 can route.

I was just curious if the different models could be stacked on almost a layer 2 functionality basis.
