Network Device Location

Internal solution that shows, based on the MAC address, which switch and port a network device is connected to.

Internal company solution – presentation abstracted for confidentiality reasons.

Problem
Network devices have to be searched for manually on switches.
Solution
Central, MAC-based mapping shows a device's switch and port.
Result
No more manual searching across several switches.

Initial situation

To find a device on the network, you had to connect to several switches and search the port tables by hand.

Problem

The search was time-consuming, error-prone and slow during incidents – exactly when speed mattered.

Goal

One central view: enter the MAC address, see the switch and port.

Solution

An internal solution collects the mapping of MAC addresses to switch ports centrally and makes it searchable.

Result

Devices are located centrally; manually searching individual switches is no longer necessary.

Business value

Faster troubleshooting and documentation, less time spent on routine searches.

My contribution

Design and implementation of the collector service, data storage and search interface.

Technical details

Architecture

A collector service regularly reads the MAC tables of the switches and stores the mapping centrally; an interface makes the data searchable.

  1. Switches
  2. Collector service (MAC tables)
  3. Central database
  4. Search by device / port
Abstracted representation without internal system names.

Technologies

Integrations, APIs and authentication

Read-only access to the switches' management interfaces.

Security

Read-only access with a dedicated service account; access to the interface for IT only.

Technical highlights

  • Central MAC-to-port mapping
  • Regular refresh instead of manual queries
