This document explains how to upgrade a Cisco IOSsoftware image on Cisco Access Router platforms. The examples provided from the 2600 and 3600 Series Routers also apply to the list of router platforms mentioned. The Cisco IOS Software file names can vary, based on the Cisco IOS Software release, feature set, and platform.
Specify the outbound file directory. This is the directory in which the Cisco IOS software images are stored. Most TFTP applications provide a setup routine in order to assist in these configuration tasks.
cisco c3600 ios image .bin file
These error messages display in the console output when the Flash is empty or when the file system is corrupted. Copy a valid image on the Flash as described in the procedures provided in this document.
The file system type flash or disk is used to store the Cisco IOS image. The show file system command output shows the list of file systems available on the router. The common disk/flash file systems supported in Cisco routers have prefixes such as flash:, slot0:, slot1:, disk0: and disk1:. It must have sufficient space to store the Cisco IOS image. You can use the show file system or the dir file_system> command in order to find the free space.
Verify if the Cisco IOS image is in the flash , if the first file in the Flash is not the Cisco IOS Software image, but a configuration file, or something else, then you need to configure a boot system statement in order to boot the specified image. Otherwise, the router tries to boot with the configuration file or the first file in the Flash, which does not work. If there is only one file in the Flash and it is the Cisco IOS Software image, this step is not necessary.
A directory that has the Cisco IOS Software release name stores the Cisco IOS image as a bin file. The directory stores the image on the system board flash device (flash:). A subdirectory contains the files that you need for web management.
The software download center for Catalyst 3750 contains two sets of Cisco IOS images for every feature set and versions. One set contains only the Cisco IOS image file which has the extension .bin. The other set contains the Cisco IOS image plus the web-based device manager which has the extension .tar.
This document explains the upgrade procedure with the .tar image as well as with the .bin image. The .tar file contains the Cisco IOS image file and the files that you need for the embedded device manager. You must use the combined tar file in order to upgrade the switch through the device manager.
The 3750 ships from the factory with the installation of a web-based device manager (.tar file) in the flash: directory. The extraction process that takes place with a .tar file creates a Cisco IOS image directory. The image directory has the same name as the Cisco IOS image (.bin file), but without the file extension. This directory stores the Cisco IOS image (.bin file) along with an HTML subdirectory that contains the device manager files.
If necessary, issue the delete flash:file_name command in order to delete a single Cisco IOS image (.bin file). Or issue the delete /force /recursive flash:dir_name command in order to delete a directory and all the files in the directory.
The procedure in this section copies the combined tar file to the switch. You copy the file to the switch from a TFTP server and extract the files. You can download an image file and replace the current image, or you can keep the current image.
In order to download older versions of the IP services image or IP base image files for a Catalyst 3750 switch, click Archived Catalyst 3750 Software . In order to obtain authorization and to download the cryptographic software files, click Catalyst 3750 Strong Cryptographic (3DES) Software.
A 3750 switch stack can be managed either with the web device manager or with the CLI. If you manage the switch with the CLI, you do not need the .tar image. This section explains the Cisco IOS upgrade with the .bin image. It is assumed that you have already configured the 3750 switch stack with a Cisco IOS image. This section explains how to copy and upgrade the new Cisco IOS in the 3750 switch stack.
Refer to Software Download - Cisco Catalyst 3750 Software and find the image that you want to download. The Software Download Center for the Catalyst 3750 contains two sets of Cisco IOS images for every feature set and versions. One set contains only the Cisco IOS image file which has the extension .bin. The other set contains the Cisco IOS image plus the web-based device manager which has the extension .tar.
For the /destination-system destination-stack-member-number , specify the number of the stack member to which the source that runs the image file needs to be copied. If you do not specify the stack member number, the running image file is copied to all stack members by default.
The reason for this error message is that the archive command is for the .tar files and cannot be used with .bin files. In order to upgrade with the .bin file, use the copy command.
If both routers are different but have a compatible PCMCIA Flash card filesystem, you can use the other router to load a Cisco IOS Software image into a Flash card, which you can then move to the router you try to recover.
Good afternoon, asmoles.Fist of all, make sure is possible to you get safely cisco imagem on Cisco.com. if not?so, validates that you pendrive format is FAT16 or FAT32. After that, connect Its on Cisco Switch, verify if switch could recognize your device:Look for something like usbflash0:Commandswitch#dirIf you switch install software Bundle mode, I can copy .bin file into pendrive:CommandSwitch# copy flash:*.bin usbflash0:
The router can store as many IOS images in its flash memory as there is space to hold. If there is only one file, it can safely assume that this must be the IOS image to load. However, if the router has several images in its flash storage, you need to specify which one it should load, or the router will simply select one. This is particularly true on routers that have additional flash memory in the form of PCMCIA cards, which can hold many files, not all of which are even necessarily IOS images.
Above you can see that I already entered the IP address and filename. Once I hit enter, it will only ask me for the destination filename (which I also could have entered). If you have to upgrade the IOS image on multiple devices, this is more convenient as you can just copy/paste the above line on all devices.
So far we copied a couple of files but how do we know that these files are valid? When we downloaded the Cisco IOS image, I showed you the MD5 checksum that Cisco publishes on their website. We can verify this checksum on our router:
This MD5 checksum is the same as the one we found on the Cisco website. This tells us that we have the same file as Cisco published and that the file has not been tampered with. If the checksum fails, maybe someone has added something nasty to the image.
Most routers will select the first filename that they find on the flash memory so in our case, it means it would boot the older IOS image. We can change this with the boot sytem command:
You have now learned how to upgrade your Cisco IOS image through TFTP, FTP and SCP. You have seen how this can be done from your computer to your router/switch or between two routers. We also checked how to verify the integrity of the file with the MD5 checksum and how to configure your router to boot the new IOS image.
All installed IOS image files are listed in the right pane of the Dynamips -> IOS routers option. Select the file which you want to manage. Once the IOS file is selected, control options will be highlighted in the bottom section.

You can use this mode/reset button when you do not know password or your AP firmware is corrupted,etc. In our case, even the firmware is not corrupted, we can use this button to load an image from a TFTP server. In this scenario, AP is looking for a specifically named image file to load. So if you keep a Autonomous image file with the correct named syntax, AP will load that image once we do this.
Third: This is where the fun begins. Ensure your AP has an active ethernet connection (mine does, as I am using PoE). Also make sure that your AP image is sitting on the TFTP server ready for imaging. This should be present in the form of a .tar file.
The AP will then continue to download and extract various files from the tar archive. The reason that a tar archive is used instead of the Cisco standard of a .bin file is because the AP includes various html files for it's built in web GUI. The lightweight image has less of these files but still includes a few.
Now the AP has booted! Given that this is an autonomous AP notice that it has by default got it's IP via DHCP. The standard credentials for APs after they've been imaged is cisco/Cisco for username/password. Note the capital "C" for the password.
If you delete on or more files from the flash DO NOT reload or powercycle the router until you finish this procedure. The flash image you are working on is currently loaded into RAM, so you can keep working properly until you reload or powercycle the router. 2ff7e9595c
