With that said, only real hardware will give you the true, unadulterated experience of working with the Cisco IOS.

My goal here is to provide you with a clear, concise path toward installing GNS3 and getting your first lab up and running based on my own lessons learned from a lot of Googling, swearing, and hair-pulling. If I recall correctly, VTP and STP are two of the feature sets that don’t work properly in Packet Tracer, and those are both important. Not all commands work in Packet Tracer, and some of them are exam topics you need to know.

To be honest, that’s what I used for the CCENT, because when I looked at my options it was either that or GNS3 and the first time I tried to figure out how to get GNS3 working my mind almost exploded.

The cheapest, easiest option is to download Cisco Packet Tracer. But how are you going to do that? Purchasing lab equipment costs money, and when you’re just starting out you aren’t going to know the differences between a 2950 or a 3570. Sure, I went at the CCENT with a baseline knowledge of networking gained from the CompTIA Network+ (and some associated concepts from the Security+), but not everything on the exam is listed on the objectives.Ĭase in point: establishing a home lab environment.Īll the objectives tell you that you need to know is how to configure certain specific feature sets, like VLANs on switches. We'll show an example below for a TFTP server.When I began looking at the world of Cisco certifications, I was overwhelmed by the sheer amount of material there was to learn. It's no secret that Wireshark is far more user-friendly than any kind of command-line analysis, so how could you do this? Simply set up a TFTP/SCP server or plug in a USB and move the captured file using the standard Cisco copy command. Let's now imagine you want to move the captured PCAP data to a desktop for detailed analysis.

Is the issue related to a firewall policy? Does it exist between the nodes or on one of the nodes themselves? Is the problem existent in one direction or both? Setting up our lab on GNS3įor today's example, we'll set up a Cisco ASAv firewall with a direct connection to a PC on GNS3. If the routing looks good but the nodes are still unable to reach each other, it might be time to perform a packet capture - this will allow the user to isolate the location of the issue. Step one would usually involve checking the routing table to ensure an entry exists for both nodes. The most frequent use case for a packet-capture is to debug a connectivity issue between two nodes. Countless times during my career I've been able to diagnose network issues with this technique. Having the skill to capture traffic within a network is essential for any ambitious network engineer.
