Create mLAG Port with XMC Python

[cslayton]

I’m writing a python script to create MLAG port.  Since the config will vary slightly between 2 devices, is it possible to write this in a single script and apply to 2 devices?

Here is my script so far.

Hmm,

so it still remains two options cslayton, either your version is too old or the license type is wrong.

As MIG has already asked. Which version and which type (Basic, Standard, Advanced) do you use?

Hello Mig,

is your version 8.1.5 correct or do you meen 8.5.1?

I can see the workflow on 8.4.4.x and 8.5.1.60 with ADV license but not an a 8.3.1.9 with Standard license.

Maybe the license is the difference if you have realy a old 8.1x.
