Relates — Sun, 26 Nov 2023 11:30:07 +0000

The device remains connected in NETCONF even when it is unreachable.

How to reproduce:
1) Connect device:

curl --request GET 'http://192.168.56.100:8181/rests/data/network-topology:network-topology/topology=topology-netconf/node=netopeer' \
--header 'Authorization: Basic YWRtaW46YWRtaW4=' \
--header 'Content-Type: application/json' \
--data '{
    "node": [
        {
            "node-id": "netopeer",
            "netconf-node-topology:port": 830,
            "netconf-node-topology:reconnect-on-changed-schema": false,
            "netconf-node-topology:connection-timeout-millis": 20000,
            "netconf-node-topology:tcp-only": false,
            "netconf-node-topology:max-connection-attempts": 5,
            "login-password-unencrypted": {
                "netconf-node-topology:username": "netconf",
                "netconf-node-topology:password": "netconf"
            },
            "netconf-node-topology:sleep-factor": 1.5,
            "netconf-node-topology:host": "127.0.0.1",
            "netconf-node-topology:between-attempts-timeout-millis": 2000,
            "netconf-node-topology:keepalive-delay": 20
        }
    ]
}'

2) Verify that the device is in a connected state.
3) Turn off the device.
