Network Topology Visualizer

Want to see a quick demo?

Load sample CDP data to visualize a network topology instantly.

Input CDP Data

Enter device information and paste CDP neighbor output

Batch Process Files

Upload multiple CDP output files for batch processing

File Format Requirements:

  • • Filename should be the source IP address (e.g., 192.168.1.1.txt)
  • • File should end with # followed by the hostname
  • • Content between "Device ID..." and "Total cdp entries..." will be processed
  • • Repeated header lines will be ignored

Labeling Controls

Show device hostnames above nodes
Show IP addresses inside nodes
Show interface names on connection lines
Only show interfaces connecting to currently visible devices
Show interface names on connection lines
Closer to line Further from line
Keep interface labels horizontal instead of following link angle
Scale text to fit within node boundaries
Lower values = shorter lines, Higher values = longer lines
Closer Further
Less More

Text Table Mode

Show "Hostname → [Int1, Int2]" instead of individual lines
Use uniform text colors (black/white) for all text
Apply category colors to endpoint/interface text lines
Apply category colors to text box backgrounds
Right-click on any node to enable/disable text table mode for that node

Visualization Settings

Customize how your network topology is visualized

Model Colors

Assign colors to device models. These colors will be used for interface and endpoint lines in text table blocks.

Canvas & Table Colors

Background color for the visualization canvas
Background color for text table blocks
Text color for switch names in tables
Text color for interface names in tables
Border/edge color for text table blocks

Table Tags

Create tags to categorize tables (e.g., Core, Remote, Distribution). Right-click a table to assign a tag.

Bulk Tag Assignment

Select tables by name pattern and assign a tag. Pattern matching is case-insensitive and matches partial names.
