Load configs from many devices (Cisco IOS / IOS-XR / NX-OS, Huawei, Juniper, Nokia SR OS). The tool reads ACLs, prefix-lists and route-maps, derives a routing table (connected, static, OSPF and BGP inferred from the configs) and answers “where does this packet go, and what stops it?” – no live access needed. OSPF and BGP are estimated from configuration, not run for real.
What it does
- Packet check: which ACL, which rule, which line permits or blocks (src, dst, protocol, port)
- Hop-by-hop trace with loop, blackhole and ACL-block detection
- ACL audit: shadowed rules, redundant rules, ACLs applied but not defined, unused ACLs; prefix-list and route-map reference checks
- Link-down / device-down simulation with a before / after path comparison and a network-wide impact table
- Excel report with routes, findings, the trace and the tool’s stated limits
How it works
FAQ
Is my data uploaded to a server?
No. Files are processed in your browser (or by the optional helper app on your own computer). Nothing is stored on our servers.
Do I need to install anything?
No – it is a web app. You can optionally install it as a desktop app from the browser. A small helper app is only needed for tools that must reach your network (ping, port check, auto login).
