specific requirements for this document. Components Used The information in this document is based on these software and hardware versions: Cisco ASA 5500 series with software version 8.0 and later The information in this document was created from the devices in a specific lab environment. All of the devices used in this document started with a cleared (default) configuration. If your network is live, make sure that you understand the potential impact of any command. Conventions Refer to Cisco Technical Tips Conventions for more information on document conventions. Background Information Cisco ASA maintains its filesystem in an internal flash memory and stores all the files in flash memory. This is a memory card inserted into a slot in the ASA. The capacity of this depends on the ASA hardware model. Refer to the Technical Specifications section in Table 8 of Cisco ASA Data Sheet for more information. This memory is referred to as flash or disk0. When additional flash memory is needed, you could use an external flash card. Except for the ASA 5505 model, all other ASA models in 5500 series have an external compact flash card slot on the rear end of

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 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 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. However, expectingchanges to the startup config to remain in GNS3using thecommand "copy run start"will leave you sorely disappointed. I found this out after a halfhour of aggravation. Cisco routersandtheir file systemsare emulated using Dynamips in GNS3.This is important to notebecause when a virtual dyn
