  • Where do I go from here?
    If you mean a Cisco 2950, I guess you want to learn Networking. So a good place to start is to run GNS3 (https://gns3.com). You can download a VM image and run that, that's what I do. GNS3 is a great learning tool and you can use both real (your 2950) and virtual devices to make networks. Source: 6 months ago

    You might want to look into GNS3. It's a network emulator that supports Cisco ISO devices. It's been a while since I last used it, but at the time I found it to be indispensable as a learning tool. Source: over 1 year ago
