200-901: Automating Networks Using Cisco PlatformsDemo

The <edit-config> operation modifies part of a target configuration datastore without replacing it, which is exactly what changing a device hostname requires. The request targets the <running/> datastore and supplies the new name inside the IOS native model's <hostname> element, and the device confirms the merge with an <ok/> in its <rpc-reply>. <copy-config> replaces an entire datastore rather than merging a single change, and operations named new-config or edits-config do not exist in the NETCONF protocol.
