It's been possible for a long time to use HTTP to download information from a web server to a router. In IOS release 12.3(2)T, integrated in 12.4 release, Cisco has introduced the ability to store local information (for example, router configurations) on a web server. To use this feature, configure the username and password giving you write access to the web server with:
ip http client username web-user
ip http client password secret-password
After the username and password have been configured, you can use copy running http: to copy router's configuration to a web server.
Note: on the web server, you have to configure the target virtual directory for write access (default: disabled) and allow file-system write access to the underlying physical directory for the target user.
Alternatively, you can specify the username and password in the URL using the copy running http://user:[email protected]/file syntax.
router#copy running http://student:[email protected]/router-config
Address or name of remote host [192.168.0.2]?
Destination filename [router]?
