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.
#@METADATASTART
#@ScriptDescription "Create mLAG Port"

# Purpose: Create mLAG Port

# type = String,

# required = yes,
# value = "mLAG-ISL",
# name = "MlagName"

#@VariableFieldLabel (

#@SectionStart ( description = "mLAG ISL Port")
