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.

Hello cslayton,

did you see the the System Workflow “Configure ISC and MLAG Peers on EXOS” (in System Workflows->Config->LAG-MLAG)?

Maybe that Workflow do the work for you. Or did you miss something?
