Netconf implementation in IOS XR

[Carsten Buchberger]

Hello all,

i have a question regarding how NETCONF is implemented in IOS XR. It seems that it is not using a separate SSH Subsystem for netconf. According to the RFC (http://www.rfc-archive.org/getrfc.php?rfc=4742) thast is not MUST, but best practice. In Cisco IOS the subsystem is there, in devices from other vendors, too.           

The problem is, that our netconf-client can only connect to Netconf via SSh subsystem. And it works with 100+ devices, but not with our ASR9K.

I found http://www.cisco.com/en/US/docs/ios_xr_sw/iosxr_r4.1/xml/programming/guide/xl41netconf.html#wp1074169 where it says

- SSH Transport—Shell based SSH. IANA-assigned TCP port <830> for NETCONF SSH is not supported

Does that mean "No subsystem" ? I hope it does not - in IOS port 830 did not work either.....

Thanks in advance

Hi Carsten,

Currently NETCONF SSH is not supported in XR. There is already a CSCug68375 enhancement
work in progress. Currently it will be supported from 5.1.1. Let me update you incase if its different.
