The following table lists currently (per 2024) assigned port numbers [IANA-SERVICE] for various NETCONF transports.¶
Service Name | Port Number | Transport Protocol | Description | Reference |
---|---|---|---|---|
netconf-ssh | 830 | tcp | NETCONF over SSH | [RFC6242] |
netconf-ssh | 830 | udp | NETCONF over SSH | [RFC6242] |
netconf-beep | 831 | tcp | NETCONF over BEEP | [RFC4744] |
netconf-beep | 831 | udp | NETCONF over BEEP | [RFC4744] |
netconfsoaphttp | 832 | tcp | NETCONF for SOAP over HTTPS | [RFC4743] |
netconfsoaphttp | 832 | udp | NETCONF for SOAP over HTTPS | [RFC4743] |
netconfsoapbeep | 833 | tcp | NETCONF for SOAP over BEEP | [RFC4743] |
netconfsoapbeep | 833 | udp | NETCONF for SOAP over BEEP | [RFC4743] |
netconf-ch-ssh | 4334 | tcp | NETCONF Call Home (SSH) | [RFC8071] |
netconf-ch-tls | 4335 | tcp | NETCONF Call Home (TLS) | [RFC8071] |
netconf-tls | 6513 | tcp | NETCONF over TLS | [RFC7589][I-D.ietf-netconf-over-tls13] |
Many of these assignments are for a transport protocol (UDP) for which the requesting application does not apply. For example:¶
"Using the NETCONF Protocol over "the Blocks Extensible Exchange Protocol (BEEP)" specification (Section 7 of [RFC4744]) states the following:¶
IANA assigned TCP port (831) for NETCONF over BEEP.¶
"Using the NETCONF Protocol over Secure Shell (SSH)" specification (Section 7 of [RFC6242]) states the following:¶
Based on the previous version of this document, RFC 4742, IANA assigned the TCP port 830 as the default port for NETCONF over SSH sessions.¶
"Using NETCONF over the Simple Object Access Protocol (SOAP)" specification (Section 5 of [RFC4743]) states the following:¶
IANA assigned TCP port (833) for NETCONF over SOAP over BEEP, and TCP port (832) for NETCONF over SOAP over HTTPS.¶
It is understood that these assignments were made when the practice at that time (prior to 2011) was to automatically assign a port number for both TCP and UDP, even if a request was for only one of these transport protocols.¶
Also, many of these assignments are for protocols that are not deployed and which were tagged as Historic: [RFC4743] and [RFC4744]. [I-D.ietf-netconf-rfc4743-rfc4744-to-historic] reported in 2012 that these two protocols:¶
"have shown very little (if any) implementations and deployment"¶
This document de-assigns these port numbers, that fall in the System Ports range.¶
Consistent with Section 8.2 of [RFC6335], this document does not request to de-assign service names; only port numbers (for specific transport protocols) are de-assigned for better usage of available scarce resources.¶
Releasing back some port number softens the exhaustion risk of available port number space (especially the System Ports range).¶
This document does not describe any protocol.¶
This document requests IANA to update the "Service Name and Transport Protocol Port Number Registry" registry [IANA-SERVICE] as specified in the following subsections.¶
