![]() ![]() I personally lean towards a Unix-like OS (like Linux or OS X) but only because I've worked with UNIX since the 80's and it's a comfortable fit for me. Even if you do want to become a CCIE (or learn advanced switching for some other reason) you can still work around these issues on OS X and Windows. However, if you don't have a need for this sort of thing, then this may not be a consideration for you. My reasoning is that Linux integrates well with Cisco IOS on UNIX (IOU), and trunks well to live physical Cisco switches. That being said, I've recently become rather fond of Linux as a host for GNS3. The more familiar you are, the easier it is to come up with a solution. ![]() You can find a work around for most things, so in the end it comes down to experience and familiarity with the underlying operating system. In my experience GNS3 runs well on all platforms, but each one presents its own unique challenges depending on what you need to do. I have installed and tested GNS3 on over dozen versions of Linux alone. However, I've spent countless hours running GNS3 on OS X, Windows, Linux, and FreeBSD. I presently use OS X as my primary operating system (in general and for GNS3). [Edit} Re dual boot - I tried that but didn't like it because once you'd booted into your alternate OS, you lost access to your Mac applications, so I went the VM path instead.įor me it will be mandatory that my new laptop run properly (and on a stable way) GNS3.Ĭan someone share their experience regarding GNS3 and MAC OS. I have seen a similar class where the instructor ran 16 router instances on his Mac Mini and each stuent controlled one. In fact I ran a class a couple of weeks back wehre I ran 10 linux virtual machines on a Mac Mini (quad core i7, 16GB RAM) and gave each student (working on old Windows XP machines) a VNC connection to my Mac Mini and they connected all 10 VMs to make a class network that was running entirely within VMs on my mac. it is a beautiful machine for carrying around and working on! And with all that power, running a virtual machine with GNS3 is not a big deal (I use vmWare fusion, but I'm sure Parallels would work just as well). On the other hand, if you can afford a Mac. Dynamips_community version 2.8 RC5 is only stable on Windows, and it has a number of improvements (the ability to do auto-calculate of idle-pc for one, AUX port improvements.), so the the most functional version of GNS3 is (at the moment) the Windows version. In the meantime, GNS3 for windows has had much more development effort than the other versions. It still does, but I have read some discouraging posts involving people who have had difficulty making the new thunderbolt adapter work, and it seems that Mountain Lion has more problems than "good ol' snow leopard" One of the major deciding factors when I bought my MacBook Pro in 2009 was seeing how well GNS3 worked on a Macintosh.
