These sections contain this configuration information: Note For a list of software images and the supported upgrade paths, see the release notes. File Format of Images on a Server or Cisco. Ensure that the switch has a route to the TFTP server. The switch and the TFTP server must be in the same subnetwork if you do not have a router to route traffic between subnets.
Check connectivity to the TFTP server by using the ping command. For download operations, ensure that the permissions on the file are set correctly. The permission on the file should be world-read. Before uploading the image file, you might need to create an empty file on the TFTP server. To create an empty file, enter the touch filename command, where filename is the name of the file you will use when uploading the image to the server. During upload operations, if you are overwriting an existing file including an empty file, if you had to create one on the server, ensure that the permissions on the file are set correctly.
Permissions on the file should be world-write. Caution For the download and upload algorithms to operate properly, do not rename image names. When you copy an image file from the switch to a server by using FTP, the Cisco IOS software sends the first valid username in this list: The username specified in the archive download-sw or archive upload-sw privileged EXEC command if a username is specified.
The username set by the ip ftp username username global configuration command if the command is configured. The switch sends the first valid password in this list: The password specified in the archive download-sw or archive upload-sw privileged EXEC command if a password is specified. The password set by the ip ftp password password global configuration command if the command is configured. The switch creates a password named username switchname. The username variable is the username associated with the current session, switchname is the configured hostname, and domain is the domain of the switch.
Before you begin downloading or uploading an image file by using FTP, complete these tasks: Ensure that the switch has a route to the FTP server. The switch and the FTP server must be in the same subnetwork if you do not have a router to route traffic between subnets. Check connectivity to the FTP server by using the ping command. If you are accessing the switch through the console or a Telnet session and you do not have a valid username, make sure that the current FTP username is the one that you want to use for the FTP download.
You can enter the show users privileged EXEC command to view the valid username. If you do not want to use this username, create a new FTP username by using the ip ftp username username global configuration command. This new name will be used during all archive operations.
If you are accessing the switch through a Telnet session and you have a valid username, this username is used, and you do not need to set the FTP username. Include the username in the archive download-sw or archive upload-sw privileged EXEC command if you want to specify a username for that operation only.
When you upload an image file to the FTP server, it must be properly configured to accept the write request from the user on the switch. Command Purpose Step 1 configure terminal Example: Switch configure terminal Optional Enters global configuration mode on the switch. When you copy an image from the switch to a server by using RCP, the Cisco IOS software sends the first valid username in this list: The username specified in the archive download-sw or archive upload-sw privileged EXEC command if a username is specified.
The username set by the ip rcmd remote-username username global configuration command if the command is entered. The remote username associated with the current TTY terminal process.
For example, if the user is connected to the router through Telnet and was authenticated through the username command, the switch software sends the Telnet username as the remote username. The switch hostname. Before you begin downloading or uploading an image file by using RCP, do these tasks: Ensure that the workstation acting as the RCP server supports the remote shell rsh. Ensure that the switch has a route to the RCP server.
The switch and the server must be in the same subnetwork if you do not have a router to route traffic between subnets. Check connectivity to the RCP server by using the ping command. If you are accessing the switch through the console or a Telnet session and you do not have a valid username, make sure that the current RCP username is the one that you want to use for the RCP download.
If you do not want to use this username, create a new RCP username by using the ip rcmd remote-username username global configuration command to be used during all archive operations. If you are accessing the switch through a Telnet session and you have a valid username, this username is used, and there is no need to set the RCP username. When you upload an image to the RCP to the server, it must be properly configured to accept the RCP write request from the user on the switch.
For UNIX systems, you must add an entry to the. For example, suppose the switch contains these configuration lines: hostname Switch1 ip rcmd remote-username User0 If the switch IP address translates to Switch1. Command Purpose Step 1 configure terminal Example: Switch configure terminal Enters global configuration mode. Step 2 ip rcmd remote-username username Example: Switch config ip rcmd remote-username netadmin1 Optional Specifies the remote username.

The word is that we can buy used routers on ebay and copy image to pc for gns3 usage; not sure how legal is that. You must consider the reason because the GNS3 has its own forum different of Cisco. The cisco products as Router, switches, etc must be get legally. The general recommendation is studying using the Cisco Packet tracer and in the work with real devices About switches I see the Catalyst series in some companies of my country.
I mean worse case I am using Cisco packet tracer so its not a big deal, I was just more curious if anything why its not possible to get them under a VIRL subscription, furthermore if I setup a VIRL environment does this then give me access to the older images?
If so that does not make much sense. Legally, the only way is copy the old image from a real physical device. So, if you do not want to invest in old physical devices, there are many illegal copies over internet but is your decision. Fair enough. All illicit copies are wrong to download, and additionally they all have malware in as well. If you encounter a technical issue on the site, please open a support case.
