ACI2DOT

aci2dot converts JSON formatted Cisco ACI policy files or snippets to a DOT graph format.

Dependencies

• Python 3 only
• pip install -r requirements.txt

Customisation

--write creates a config file .aci2dot in the current directory, which allows for modification of the graph, node and edge properties.

The default config is as following:

{
  "node": {
    "shape": "box", 
    "fontname": "Helvetica", 
    "style": "rounded,filled", 
    "fillcolor": "AZURE"
  }, 
  "graph": {
    "rankdir": "LR", 
    "splines": "true", 
    "bgcolor": "white", 
    "ranksep": "0.2", 
    "dpi": "300", 
    "nodesep": "0.2"
  }, 
  "edge": {
    "arrowsize": "1"
  }
}
