FTD Multi-Instance Data and Data-Sharing Interface

[leonardo_neves]

Hi,

I need to change a production interface from Data to Data-Sharing, but I can't find in documentation if is possible to do in a production interface without downtime or the step-by-step to do it.

Is that possible?

how is your existing setup configured on switch side and FTD side, I do not believe with out downtime this is possible,

You need to convert this as trunk mode or port channel with a sub-interface for other instances to use it. on other side switch side you need to change the configuration also.
