Override Cabling (JSON)

Situations when you might want to edit the cabling map include:

  • to use existing network cabling instead of recabling to the Apstra-prescribed cabling
  • to change interface names or IP addresses in the existing network cabling map
  • to specify a different port from the one that the Apstra cabling algorithm selected
  • to avoid the use of a defective interface

To change the cabling map with a JSON file, you'll export the JSON file, edit the file, then import it back into Apstra.

CAUTION:

Overriding Apstra-generated cabling can be disruptive to the network. Use with extreme caution. For assistance with production networks, please contact Juniper Support.
  1. From the blueporint, navigate to Staged > Physical > Links and click the Export cabling map button to see the dialog for exporting a cabling map.
