The reason I wrote this script script was to provide CLI support for Cisco Catalyst Express 500 series switches. The organization I used to work for decided to standardize on this model of Cisco switch because they are very cheap, and are comparable in hardware/software capability to Catalyst 2960 series switches. The downside is that this line of switch does not have any Telnet, SSH, or console access built into its IOS; Only http access.

Further to that, the CE500's don't directly support CLI access to its http service. In order to execute arbitrary commands on the device that aren't directly supported in its http gui interface, you need to send requests to the http service as specifically formatted GET or POST requests. This particular script uses a hidden CGI script hosted by the http service to process commands.

In short, there's no reason to use this script unless you have Catalyst Express 500's deployed in your organization.
