🔍 This project, 'Meraki BSSID Dump', is a Python script created to export BSSID (Basic Service Set Identifier) information from an organization's Meraki wireless networks. The primary use case is to retrieve BSSID details for manual import into geolocation data services (e.g. e911). It provides network and facility administrators with a simplified method to gather bulk BSSID information.

CSV file example output:

The document "Calculating Cisco Meraki BSSID MAC Addresses" offers a comprehensive guide on how BSSID MAC addresses are computed for Cisco Meraki access points. Each SSID is represented by a unique BSSID, which helps clients identify the associated access point. The BSSID addresses are derived from the wired MAC address, with calculations based on the MAC OUI. Different MAC OUIs for various access point models determine the adjustments for 2.4 GHz and 5 GHz bands. The BSSID values are assigned to each radio and SSID, with up to 15 possible BSSID combinations per radio.

🔧 The script is written in Python and utilizes the Meraki DashboardAPI to interact with the Meraki cloud. Python was chosen for its simplicity and the comprehensive support provided by Meraki's Python SDK.

✅ The current version of the script is stable (1.0), but updates and improvements may be implemented as needed.

🎯 The script's primary use case is to export BSSID details for e911 services location data. However, it can also be beneficial for large enterprises such as colleges and hospitals. Here are a few additional use cases:

• Colleges and Universities: In a college or university environment, the script can help network administrators identify and manage BSSIDs across multiple campuses, buildings, and access points. This information can be useful for optimizing network performance, monitoring network utilization, and ensuring proper coverage across campus areas.

• Hospitals and Healthcare Facilities: For hospitals and healthcare facilities with complex network infrastructure, the script can assist in monitoring and managing BSSIDs. It allows network administrators to track the performance of wireless networks in different areas within the facility, ensuring critical connectivity for medical devices, patient monitoring systems, and staff communication.

• Enterprise Networks: In large enterprises with multiple branch offices and locations, the script can provide network administrators with a consolidated view of BSSID details across the organization.

To install and use the script:

1. Clone the repo using the following command:

git clone https://github.com/shantarsecurity/meraki-bssid-dump.git
cd meraki-bssid-dump

2. Install the meraki package:

pip3 install meraki

Before running the script, make sure to replace 'Your Meraki API Key' in the script with your actual Meraki Dashboard API key.

To execute the script, use the following command:

python3 meraki-bssid-dump.py

The script will generate a bssid.csv file in the same directory, containing the fetched BSSID details.

⚠️ Running the script on networks with a large number of devices may take some time due to the rate limit imposed by the Meraki API. It is advised to run the script during off-peak hours or schedule it accordingly.

🔮 Future versions of the script may include added features such as a progress display, filtering options, and customized output formats.
