Need help attach cEdge (C8000v) CLI Template - I get weird error

[shlomyb]

Hi there,

I'm running on LAB (in order to learn and practice) SD-WAN Scenario vManage/vSmart/vBond running version 20.9.3.1

running as cEdge - Catalyst 8000v running version 17.11.1a

I've successfuly added the Edge devices to the vManage

yet - when I try to create a simple CLI Template and attach it I get an error.

the steps I've taked - 

1. Created a new CLI Template, Choose C8000v
2. When creating the CLI Template I've used "Load running config from reachable device:" and chose one of my cEdge devices.
3. I've changed what I wanted to be modified like system-ip, site-id etc.
4. I've attached it to the same devices that I've used its running config
5. when I try to see the confug diff before applying the template I get an error - 

"Server error: ip syntax error: element does not exist Error: on line 139: ip scp server enable"

so as a workaround I've tried to remove the line "ip scp server enable" from the CLI Template.

the error did not appear - now I can use the Config Preview and Config Diff.

BUT

when I click on Configure Devices I get the following error "Failed to configure device with Template"

check the compatable matrix, the controller version not compatable you need higher version for the cedge to work :

Ideally you want the controller and edge devices to be aligned on code versions.   That means if the controller is on 20.9.3 then edge should be on 17.9.3 code.    The second number should be the same.   The yang models can change and cause issues when trying to attach devices if the code versions are not aligned.
