Well I had network manager by Network-Manager. For some reason I have to put the same configuration in /etc/network/interfcaes. Here's result of ifconfig before changes
enp0s17 Link encap:Ethernet HWaddr 08:00:27:d4:30:fe

With the same configuration as reference I created a new file /etc/network/interfaces as
auto lo
iface lo inet loopback
auto enp0s1
iface enp0s1 inet static
address 10.1.178.179
netmask 255.255.255.0
getway 10.1.178.1
I made a small change in the interface-name. In place of enp0s17 I tried using enp0s1 and enp0s17:1(virtual interface is where I am heading).
But, I am not able to take this configuration up. I have done,
First, I did systemctl stop network-manager && systemctl restart networking.

Furthermore I tried ifdown enp0s17 --force successfully, verified as
$ cat /run/network/ifstate
lo=lo
followed ifup enp0s1 --verbose --force, which results

Failed to bring up enp0s1.
Any help would be appreciated.
UPDATE
After reading through this andThis, my problem scope has reduced.
How can resent the network-interface-name assigned by udev like from enp0s17 to enp0s1 or so ?
And, how can I go ahead adding virtual-network-interfaces aka network-alias, because they will be requiring new names as enps01:1 or enp0s1:2 and likewise ?
Additionally I am missing rule files under /etc/udev/rules.d and am not able to regenerate it as well. Somewhat similar to this post.
FURTHERMORE
A network-alias can be added in GUI using Network Manager like this. How can this be done in CLI, becuase in Server is not supposed to have GUI.
