Start a NETCONF over SSH session
```
s70515#netconf start-client
```
Once the NETCONF session is open, the NETCONF server (EOS device) advertises its capabilities.

You must advertise the client capabilities. Example:
```
<hello xmlns="urn:ietf:params:xml:ns:netconf:base:1.0">
<capabilities>
<capability>urn:ietf:params:netconf:base:1.0</capability>
<capability>urn:ietf:params:netconf:capability:candidate:1.0</capability>
<capability>urn:ietf:params:netconf:capability:confimed-commit:1.0</capability>
<capability>urn:ietf:params:netconf:capability:writable-running:1.0</capability>
<capability>urn:ietf:params:netconf:capability:validate:1.0</capability>
</capabilities>
</hello>
