Can't configure Junos 18.x using napalm

[mkhachfeh]

Describe the bug
Hi All,

I was using salt-sproxy for a while with our Juniper-based network, and all was working fine.

I started to find some problems with the new Junos code we use (18.x)

I can communicate with the device (net.connected, net.cli, grains....etc), but I can't configure anything on it via neither net.cli nor net.load_config/template, the device isn't reporting back any diff, and sees that the new configs are already configured, even if the new set file contains new configs not configured on the device for sure.

And I can see nothing coming back from the device via rpc-reply while debugging the request.

I tested that for multiple Juniper devices with the same code, and all are the same wrong behaviour.

For example:
- The working operational scenario:

salt-sproxy '10-220-1-9' net.cli 'show system license'
10-220-1-9:
    ----------
    comment:
    out:
        ----------
        show system license:

            License usage: none

            Licenses installed: none
    result:
        True

- The non-working configurational scenario 1, again: vlan888 isn't configured on the device 100%:

salt-sproxy '10-220-1-9' net.load_config text='set vlans vlan888 vlan-id 888'
10-220-1-9:
    ----------
    already_configured:
        True
    comment:
        Already configured.
    diff:
    loaded_config:
    result:
        True


mkh@sw220-1-9> show configuration vlans vlan888

{master:0}
mkh@sw220-1-9>

- The non-working configurational scenario 2:

root@/etc/pillar# cat /etc/salt/ext/REQ.set
set vlans vlan888 vlan-id 888


root@/etc/pillar# salt-sproxy '10-220-1-9' net.load_config filename='/etc/salt/ext/REQ.set'
10-220-1-9:
    ----------
    already_configured:
        True
    comment:
        Already configured.
    diff:
    loaded_config:
    result:
        True


mkh@sw220-1-9> show configuration vlans vlan888

{master:0}
mkh@sw220-1-9>

Within debug what I see during that is the following:

Just last note that the same set file+ net commands are working for another Junos code different than 18, tested on 20.4 and 15.1 with no similar problem

Wish it is clear, and thanks in advance.

@mirceaulinic your ideas here will be super appreciated

Just to complete the scenario:
I tested configs via napalm library from the same host toward same Junos gear, and it success

sh-3.2# cat conf.set
set vlans vlan888 vlan-id 888
-------------------------------
sh-3.2# cat connect_to_junos.py
import napalm
from pprint import pprint as pp

driver = napalm.get_network_driver('junos')
device = driver(hostname='10.220.1.9', username='myuser', password='')

device.open()
device.load_merge_candidate(filename='conf.set')
pp(device.compare_config())
device.commit_config()
device.close()
-------------------------------
sh-3.2# python connect_to_junos.py
'[edit vlans]\n+   vlan888 {\n+       vlan-id 888;\n+   }

So it is proof that it isn't a napalm issue

Today I tested netconf with the rpc's which are generated with salt command, and it worked smoothly:

sh-3.2# ssh mkh@10.220.1.9 -s netconf
<!-- No zombies were killed during the creation of this user interface -->
<!-- user mkh, class j-super-user -->

So I can ignore that it is netconf problem

Another update:

I tested the configs using salt minion, not salt-sproxy, and it worked smoothly with no problem.

So seems to me it is a limitation in salt-sproxy only, not on related packages.
