I haven't used GNS3 in a few years. When I decided to use GNS3 as a study tool for my CCNA Security exam, I found some features didn't perform expected. In this post,I wanted to highlight some unexpected problems and lessons learnedduring my studiesusing GNS3. 1. Connecting anything other than a Dynamips device to a Cloud The GNS3 cloud device is used to bridge a connect betweenyour physicaland virtual GNS3equipment. The cloud can also be used for connecting to https://supportforums.cisco.com/document/23391/error-formatting-slot0-can-not-find-flash-algorithm-error-message-displayed-during a remote GNS3 lab or even virtual machines using hypervisors other than VirtualBox. When designing my physical/virtual topology, one thing I immediately noticed isthat you could not directly connect a cloud to a qemu based device (Juniper Router, Cisco ASA, Cisco PIX, Cisco IDS)or a virtual box host to a NIO Ethernet cloud. In fact, doing so produces http://ndmiller89.blogspot.com/2013/09/episode-2-five-quirks-i-noticed-in-gns3.html the following dynamips error message: "Device does not support this type of NIO. Use an ETHSQ or hub to bridge the connection to the NIO instead." This is a dynamips generated error message. My take is thatdynamips is beingused tobridge the connectionbetween the physical NIC on the host machineto the qemu baseddevice (which is essentiallya virtual machine using the qemu wrapper). As a result, dynamips cannot detect the type of interface on the other end of the connection. This problem is mitigated by using an EtherSwitch or a GNS3 switch or hub device to bridge the connection between a non dynamips based device and a GNS3 cloud. I constructed the following connection guide to illustrate how this works. 2. The Command "copy run start" is not Enough Don't get me wrong, you should always issue this command to commit changes to the startup config. Omitting this important command in any lab simulation during the CCNA or CCNA Security will be a huge detriment to your overall score. How

I don't think you can erase the flash like you would on a real router. Author Posts Viewing 2 posts - 1 through 2 (of 2 total) You must be logged in to reply to this topic.

Now the disk0 is working after format. But show flash still doesn't work. My question is: Does the "flash" in "show flash" mean the internal flash memory while disk0 mean the PCMCIA flash card? Thanks for help!
