Cisco devices all run some version of the Cisco Internetwork Operating System Cisco IOS. This comes with a simple file management system, which allows you to organize files into folders, download, and upload them. Like on your PC, you can store files on a router. In this article, we are going to discover the internal storage of Cisco devices, and how to use it.
We will then see how we can upload and download files from a remote server, using TFTP or FTP. We can try part of what we will learn from this cisco ios download ftp with Packet Tracer.
Therefore, this article comes with a free Cisco Packet Tracer lab that you can download by clicking on the link below. Once you downloaded it, just open it with your Packet Tracer. You will be able to try what you learn the time you read it: practice will make boost your learning, cisco ios download ftp.
For this lab, the topology is clean and simple. Our focus is on a single router, with the interaction of a server. As a result, all we need is a router and a server, with a switch to connect them. Our router is The switch is just blank, and has no IP address, all working in VLAN 1. Due to the limitations of Packet Tracer, we have one simple requirement: downloading a specific file cisco ios download ftp the cisco ios download ftp. However, we will also see the syntax to check the files on the router, cisco ios download ftp, and how to use TFTP and FTP.
In other words, our final goal is to be a master of File Management on Cisco IOS. The majority of Cisco devices store files in two hardware components: the Flash cisco ios download ftp NVRAM. Flash and NVRAM are implemented with different technologies, as they have different functionalities. The NVRAM is a simple Non-volatile RAM with the main purpose of holding the startup configuration. The flash, on the other hand, is an SSD device of a few MB in size and holds different files.
Among them, we have the image of the operating system, and the VLAN Database only for switches. In the following table, a quick comparison between the two. Probably, you will never need to work with the NVRAM. Instead, you will have a cisco ios download ftp to cisco ios download ftp with the Flash. The most common thing you will do with it is downloading a new IOS image to change the boot of the device. However, you can also use it to store some logs and then push them to a server.
A Cisco IOS image is a file containing the operating systemnormally in. bin format. You can think about it like the DVD containing Windows 7, or Windows Instead of being a physical disk, it is a virtual one represented in the form of a single file. When a router boots, it looks for that file in the flash, cisco ios download ftp. You can download a more recent version and remove the old file to upgrade your router.
As simple as that. Then, you can use a file path like in the Windows file management system. For example, cisco ios download ftp, if you are looking for the file named conf.
You are going to interact with remote servers. Each remote resource is identified with a virtual partition which correspond to the protocol we use to access the resource. All virtual partitions use a double slash, not just one. However, unlike local partitions, here you need to reference two things: the path to the file and the IP address of the server.
To do that, we add the IP address followed before the path. For example, if we try to access a file on Of course, we can always use a name instead of an IP address, if our router has DNS servers configured. In Packet Tracer, we can only use TFTP and FTP. However, cisco ios download ftp, in real-live we can connect to TFTPFTPHTTPand SCP Secure Copy.
These protocols may require you to authenticate. To do that, we need to specify the password and username in the path. To do that, we insert the username and the password, separated by a column, before the IP address. To copy a file, we use the copy command in privileged exec Router.
This command expects to cisco ios download ftp the source file and the destination file name. Below, a quick example. You can only reference partitions, like with copy tftp: flash:. With this syntax, the router will guide through a wizardasking you to insert the remote server IP, the remote file name, and the destination file name.
You will be prompted to override if the file already exists. For this lab, we need to copy a file named asak8. binwhich resides on the TFTP server You can just hit enterand it will use the same name as in the source. This can save you a lot of time, since IOS images have fairly complex names. A very common way to use it is show flash:which results in the following output on our current lab.
As you can see, this commands list all the files in the folder, and specify the size Length, in byte of each. At the end, it shows a recap of the total memory used and available. When working on Cisco devices on a daily basis, you may want to move easier in the file system.
To do it, you can create folders and delete files with the following two commands, cisco ios download ftp. On some Cisco low-band products, copying from an FTP server is not supported. TFTP is always supported, but it is incredibly slow if compared to FTP. So, copying files from distant locations, or using a poor bandwidth, will be a real pain using Cisco ios download ftp. But you can play a trick to overcome that.
If you have, in the same LAN, a device supporting FTP download you can download items on that device. Then, on Cisco devices, you can run a small TFTP server. Other devices will point to your central Cisco device and download it from there in TFTP.
A common example is a remote site where the router supports FTP, but switches support TFTP only. To host a file in TFTP cisco ios download ftp a Cisco device, just run tftp-server command, followed by the full path.
Below, an example. Now, you will be able to access conf, cisco ios download ftp. txt from a device by pointing at the IP of the router in TFTP. In this article, we learned how to work with the File Management System on Cisco devices.
We cisco ios download ftp how to copy files, delete and create folders and what are the available partitions. Below, the commands you absolutely need to take with you. With the knowledge of this article, you have a new skill under your belt to use in your day-by-day networking.
With that, you will cisco ios download ftp ready to upgrade Cisco devices. Keep following the Free CCNA Course, and you will learn advanced troubleshooting techniques before diving into a more complex overview of the switching technologies. A special thanks to gigi, who pointed out that the last version of Packet Tracer supports also FTP. In Packet Tracer, we can only use TFTP servers. Errata corrige! In Packet Tracer can use also FTP servers, cisco ios download ftp.
Router RO: R0 config no ip domain lookup R0 config ip ftp username gigi R0 config ip ftp password class R0 copy ftp: flash: Address or name of remote host []? bin Destination filename [asak8. bin … [OK — bytes]. bin 3 cuniversalk9-mz. bin 2 sigdef-category. xml 1 sigdef-default.

Not only have I modified that sentence, I also added a special thank to you for pointing that out. And very nice demonstration! File Management in Cisco IOS Flash, NVRAM, TFTP, FTP.
