This template designed to parse Juniper JunOS configuration and LLDP neighbors.

Commands parsed:

  • show lldp local-information - to extract local hostname
  • show lldp neighbors - to extract LLDP neighbors
  • show configuration interfaces | display set | no-more - to extract interfaces confgiuration and LAG details
  • show interfaces detail | no-more - to extract interfaces state to add all connected devices
