For when SNMP isn't an option.

Most topology tools ask for read/write SNMP, a monitoring server, and months of setup. If you've ever walked into a client site without credentials or pushback from security, you know the problem.

The usual way
SNMP polling, agents, monitoring servers.
  • Needs read/write SNMP on every device
  • Security review before anything gets deployed
  • Dedicated server, database, licensing
  • Weeks before the first topology renders
  • Breaks quietly when VLANs change
NetDiscGen
Parse what you already have.
  • Reads config files — Network Discovery Generator never touches the network
  • Interactive topology viewer runs in the browser
  • Works with configs from any network — including air-gapped
  • Generate a site topology in seconds1
  • Re-run anytime configs change

Don't have the configs?
Pull them.

Global Capture handles secure SSH or Telnet retrieval on a schedule. Set it once — your topology stays current without anyone logging in and pasting. Included free with a verified NetDiscGen account.

Schedule, authenticate, go.

Provide a CSV of site names and IPs. Provide credentials — one set, or per-site. Global Capture logs into each device as read-only and pulls show commands that are defined by you or use the defaults, then organizes the output for NetDiscGen to parse.

  • SSH v2 and legacy Telnet
  • Credentials encrypted at rest
  • Schedule hourly, daily, or on-demand
  • Retry logic + per-device status log

* Free with purchase · bound up to 2 devices · additional seats available

Built for multi-vendor networks.

Cisco IOS and IOS-XE are fully supported today — including hybrid Cisco networks with non-Cisco devices like Juniper, HPE/Aruba, and other vendors mixed in. Native parsing for NX-OS and other vendors is in active development.
