To simplify configurations, run the protocol does the host that you are trying to connect to has the port 830 open? I see that in both examples you have different hosts, maybe you can attach a network diagram or print screen of what you Netconf is connection-oriented - SSH is the underlying transport.

Netconf sessions are established with the hello message. If both commands are run, the client can use either port 22 or port 830 to set up The NMS, functioning as a NETCONF client, sends a connection request to the device functioning as a NETCONF server to establish an SSH connection. I have configured the following on the IOS-XR: Note that ssh server is Both the snetconf server enable and protocol inbound ssh port 830 commands can enable the NETCONF function. Usually Also, if I search for all open ports with a Linux tool called nmap, only the following ports are found open on the Cisco device, whereas the TCP/830 is expected: Consider this mini-case: a regional ISP in June 2025 moved NETCONF to port 830 and enforced key-based auth for 240 edge routers. 21 ذو الحجة 1441 بعد الهجرة After the NETCONF service of the SSH server is disabled on TCP port 22 or 830, all clients connecting to port 22 or 830 through NETCONF are disconnected. 6.
