OfflineLab

Remote device configurator and collector:

Report the state of a network topology.

• A test case defines a particular configuration of the network (for each device: credentias + configuration commands) for which you want to collect the network state.
• The program reads commands from test case yaml files and executes them remotely on the devices to set a particular situation, and then for each device (yaml file with the name of the device) it reads the commands that will collect inf.
• If your network changes its state overtime with the same configurations, then you need to recollect inf. after defined periods of time.
• For each command for each device, the results are saved into a file and an XML file is built with all inf. about testcases, testruns and result file names.
• The xml file is read by a flash application to show the offline status of the topology under each of the test run of every test case.

For now it supports Cisco IOS/IOU/IOSv and *nix systems, more to come.

Example of Cisco device command file: IOU-cmd.yaml

# YAML
IOU1:
  - device: cisco
  - ip: 192.168.0.201
  - login: admin
  - password: cisco
  - enablepassword: 
  - sleep:  0
  - sh ip cef vrf CustomerA
  - sh ip cef vrf CustomerA detail
  - sh ip vrf interfaces CustomerA
  - sh ip protocols vrf CustomerA
  - sh ip route vrf CustomerA
  - sh ip cef vrf CustomerB
...

Example of Linux device command file: PC1-cmd.yaml

# YAML
PC4:
  - device: linux
  - ip: 172.17.0.4
  - login: root
  - password: gns3vpc
  - enablepassword:
  - sleep:  0
  - uname -a
  - lsb-release -a
  - ping -c3 100.5.0.5
  - traceroute 100.5.0.5
  - ip -4 route show
  - ip -6 route show
  - ip -6 a
  - ifconfig
  - ip -6 neighbor show
  - cat /proc/net/if_inet6
  - sysctl -a
  - free mto
...

Example of test case configuration file for a Cisco device: case1.yaml

# YAML
R4:
  - ip: 192.168.0.204
  - login: admin
  - password: cisco
  - enablepassword: cisco
  - sleep: 10
  - conf t
  - interface e0/0
  - sh
R1:
  - ip: 192.168.0.201
  - login: admin
  - password: cisco
  - enablepassword: cisco
  - sleep: 10
  - conf t
  - interface e0/0
  - sh

An example of deployment:

python offlinelab.py

INFO:main: **** Test run 1 started ****
INFO:main: **** Case 1 collecting device states ****
INFO:paramiko.transport:Connected (version 2.0, client Cisco-1.25)
