Specify which operations, or capabilities, the emitter supports from among those defined in the NETCONF specification. The client application must emit the <hello> tag element before any other tag element during the NETCONF session, and must not emit it more than once.
<capabilities>—Encloses one or more <capability> tags, which together specify the set of supported NETCONF operations.
<capability>—Specifies the uniform resource identifier (URI) of a capability defined in the NETCONF specification or by a vendor. Each capability from the NETCONF specification is represented by a uniform resource name (URN). Capabilities defined by vendors are represented by URNs or URLs. For a list of the capabilities supported by the NETCONF server for the JUNOS software, see Exchanging <hello> Tag Elements.
<session-id>—(Generated by NETCONF server only) Specifies the UNIX process ID (PID) of the NETCONF server for the session.
