Tool for synchronizing VLANs between Cisco devices and a DB

• load configuration setting from vlan_sync_cfg.yml
• have 2 loggers: poller and db
• user/pass credentials to be supplied as environment variables: USERNAME, PASSWORD
• It can load inventory from inventory.yml file and from remote sources (not implemented yet)
• As ORM it is using SQLAlchemy with an in-memory database for testing the script
• I'm using Netmiko. Scrapli and pyATS/Genie are too big to install just this test/tool

• Only with 2 items is not possible to identify what is new and what is deleted, between different runs of the tool
• One option is to rely in a SoT to enforce VLANs accoding the DB
• Another option to achieve consistency without a Single Source of Truth (SoT), is to add a 3rd item, a previous VLANs in the device, with another table in the DB And so we will be comparing
  • previous VLANs in device
  • current VLANs in device
  • VLANs in DB general table
• From there take the decision where to apply the add/mod/delete
• Testings are not complete. Just started
