Config Builder

What it does: builds a device configuration for you from a template — you fill in a short form (hostname, IP, VLANs, and so on) and it writes out the full config text for your vendor, with a live preview you can copy.

Templates: switch jobs (bootstrap, VLANs, access/trunk ports, an SVI) AND router jobs (OSPF, DHCP server pool, NAT/PAT overload, extended ACL, static routes). The router templates target Cisco IOS-XE; picking a vendor that can't render one shows a short note (and the Setup wizard / quick-setup auto-switch you to Cisco IOS-XE for it).

Guided options: a 3-step Setup wizard (role → platform → task) walks you to the right template, and Quick-setup buttons jump straight to common jobs. You can also SAVE YOUR OWN template: paste any config, mark the fill-in parts with {{placeholders}} (each becomes an editable field), and it's added to the list. Literal credentials in a saved template are masked to ****** on save — use {{placeholders}} for secrets you'll fill in later.

What you need: to know a few basics about the device you're configuring (its vendor, and the values you want). Supported vendors: Cisco IOS-XE, IOS (classic), NX-OS, IOS-XR, Arista EOS, HPE Aruba CX, Juniper, MikroTik, Ubiquiti (a template that doesn't apply to a chosen vendor says so instead of emitting wrong config). (Firewalls aren't covered — a modern Cisco firewall is policy/FMC-driven, not line-by-line CLI, so it doesn't fit a text template builder.) No connection to the device is required — this only generates text.

Safe to run: yes — it never touches a real device. It just produces config you review and paste yourself (use Provisioning or Console to actually apply it).

Reading results: the preview pane is the config that would be applied. Read it top to bottom before using it, change the form and watch it update, then Copy. Treat generated config as a strong starting point, not gospel — confirm interface names and IPs match your real gear.
