Cisco CCNA (640-553) Security Exam Training – Using the “Binary File” Command
In today’s article, I’m going to inform you about the Cisco IOS tti-registrar configuration mode command named “binary file.”
CCNAs (like you) use the command to specify the binary file location on the registrar and the destination binary file location on the petitioner.
In other words, you can use the command to specify the location where a binary file will be retrieved from the registrar and then copied to the petitioner during a Trusted Transitive Introduction (TTI) exchange.
Note: It’s possible to have nine binary files being transferred, and each one having a different source and destination location.
Below is the command’s syntax:
binary file sourceURL destinationURL
As you can see, the command uses a source and destination URL argument.
sourceURL - This argument is used to specify the source URL on the registrar from which to retrieve the binary fie.
destinationURL - And, this argument is used to specify the destination URL on the petitioner for which the binary file will be placed.
Below are the Source and Destination URL keywords with their descriptions:
archive:– Retrieves from the archive location.
cns:– Retrieves from the Cisco Networking Services (CNS) configuration engine.
disk0:– Retrieves from disk0.
disk1:– Retrieves from disk1
flash:– Retrieves from flash memory
ftp:– Retrieves from the FTP network server.
http:– Retrieves from a HTTP server.
https:– Retrieves from a Secure HTTP (HTTPS) server.
null:– Retrieves from the file system.
nvram:– Retrieves from the NVRAM of the router.
rcp:– Retrieves from a remote copy (rcp) protocol network server.
scp:– Retrieves from a network server that supports Secure Shell (SSH).
system:– Retrieves from system memory, which includes the running configuration.
tar:– Retrieves from a compressed file in tar format.
tftp:– Retrieves from a TFTP network server.
tmpsys:– Retrieves from a temporary system location.
unix:– Retrieves from the UNIX system location.
usbtoken:– Retrieves from the USB token.
Below is an example of the command being used:
Router>enable
Router#configure terminal
Router(config)#crypto provisioning registrar
Router(tti-registrar)#pki-server cs1
Router(tti-registrar)#binary file http://myserver/file1 usbtoken0://file1
Router(tti-registrar)#binary file http://myserver/file2 flash://file2
Router(tti-registrar)#end
Router#copy run start
In the example above, we are specifying on the registrar where the source binary files are located and where the binary files will be copied to on the petitioner.
By the way, if you decide to use the command, make sure your router(s) is running Cisco IOS 12.4(15)T or higher.
