topo-tool

This tool pulls mac-addresses from a list of HPE7-Comware-Switches and compares them with those saved on a Aruba-Clearpass (NetworkAccessControl).

From this comparison, the program can allocate which switch-port belongs to which hostname.

I wrote this tool, because I was instructed to inventory the location all computers at work. Even though I could not figure out the exact room, with this tool I could get the house in which the device is standing. This was a huge time save for me.

Running without docker

Before running this tool you need several setup/in-mind:

  • You need a network-connection to comware-switches and to a clearpass-api.

  • username + password for the switches and the clearpass (create an api-reader)

  • data/cred.txt containing the credentials, which looks like the following.

## Clearpass API-User
api_user=<user>
api_password=<password>

## User for Comware-Switches
sw_user=<user>
sw_password=<password>

  • A mysql/mariadb-database called topology-tool setup from db/setup.sql.

  • latest htmx-library in web/js/htmx.min.js

    • Linux: wget https://unpkg.com/htmx.org@1.9.4/dist/htmx.min.js > web/js/htmx.min.js
    • Windows: (wget https://unpkg.com/htmx.org@1.9.4/dist/htmx.min.js).Content | Out-File -Path web/js/htmx.min.js

Web-Interface

You can run/build the web/server.go to get a web-interface for searching through the database. The address is localhost:8181/topotool.
