Description:
autocml 0.0.5
AutoCML
Authentication
This library (and associated scripts) supports authentication via environment variables. This library supports a variety of different variable names, meant to suit the different names Cisco already uses.
Purpose
This Library
VIRL Library
Breakout Tool
Example
CML Controller
CML_HOST
VIRL2_URL
BREAKOUT_CONTROLLER
192.168.0.50
Username
CML_USER
VIRL2_USER
BREAKOUT_USERNAME
admin
Password (Base-64)
CML_PASS64
cGFzc3dvcmQ=
Password
CML_PASS
VIRL2_PASS
BREAKOUT_PASSWORD
password
Any combination of the above variables can be used, although the leftmost variable name will be prioritized in case of conflicts. Using CML_PASS64 is recommended (and prioritized over other password variables) to prevent the likelyhood of successful shoulder-surfers.
Bash example
CML_HOST="<cml server hostname/IP address>"
CML_USER="admin"
CML_PASS="password"
Note: Above example uses a plaintext password. I first recommend converting it to base64, then passing it in a CML_PASS64 environment variable.
Installing
The following should work in both Linux/Bash, and PowerShell.
pip install virl2-client # Install official VIRL/CML library from Cisco
pip install autocml # Install this library + associated utilities
Scripts
This library includes common scripts/commands useful for administrative purposes, or for automating common lab scenarios.
cml-add-users
Loads in a CSV file containing a list of users (a sample CSV can be saved by running cml-add-users --template <OUTPUT TEMPLATE FILENAME>
By default, it adds the users in the csv file to the authenticated CML instance. It only adds/affects users that do not already exist.
Can also delete users that are listed in the csv, if a --delete flag is passed.
Example template:
Username,Password,Full Name,Description,Roles,Groups
user1,plaintext password,User One,The first user,admin,admin_group
user2,another_password,User Two,The second user,,"net378,net123"
Example usage: cml-add-users <USER CSV FILENAME>
View help info for more details (cml-add-users --help)
(Currently untested as the primary author does not have admin access to a multi-user instance)
cml-verify-ints
Asserts a lab's interfaces against a .csv file. The csv file must have exactly three columns, (device ID/label, interface, and IP address (with optional CIDR notation)) and may look like the following:
Node Label,Int,IPv4
n0,GigabitEthernet0/0,192.168.0.24/26
R2,Fa0/2,10.1.34.2/24
R3,L1,10.255.0.3/32
One ran, it will print a report showing which interfaces match, or do not match. Interfaces not listed will not be checked.
Can also dump a CSV of interfaces, that can later be used with this utility to double-check interface addresses.
Also has a flag to emit results as JSON, although it cannot read in JSON inputs.
cml-bulk-labs
Allows for downloading/uploading/deleting lab YAMLs in bulk for archival purposes. Useful when migrating YAML labs files from one CML controller to another (like for a fresh upgrade).

cml-dump-cfgs (WIP)
cml-dump-cmds (WIP)
cml-dump-pings (WIP)
cml-pcap (WIP)
cml-start-session (WIP)
Opens a tabbed terminal emulator to have a tab for each node's console within a lab.
