Your NETCONF script connects to an IOS XE router with ncclient over port 830, then calls m.edit_config(target="running", config=payload) to rename the device to edge1, and the attempt fails with an error before the hostname changes. Which XML payload should the script pass to edit_config for the hostname change?
Select an answer to reveal the explanation.
Short Explanation
ncclient builds the RPC envelope for you, so the string you pass should contain the edit-config payload, not RPC framing. That payload has a config root in the NETCONF base namespace, and the native subtree uses the Cisco IOS XE native-model namespace. Missing the required wrapper or namespaces can cause the request to fail before the hostname changes.
Full Explanation
ncclient's EditConfig request assembles the edit-config operation and adds the target datastore you named. The payload must be rooted at a config element in the NETCONF base namespace; inside it, place the subtree being changed, here the native container in the Cisco-IOS-XE-native namespace carrying the hostname leaf. Handing over a full rpc envelope describes manual RPC framing, which ncclient already supplies. Passing the bare native fragment omits the required config wrapper. Passing a whole data document from get-config is not the appropriate edit-config payload: edit-config applies configuration data according to its operation semantics, and the default operation is merge rather than wholesale datastore replacement. Error wording can vary across releases and device handlers, so do not memorise a particular message. Practical check: print the payload and confirm it has the NETCONF-namespace config root and the native-model namespace on the subtree.
