New install NSO and Connect with XR by CLI/Netconf NED
8月 7th, 2019,由 frank撰写
Not update any NSO article to my blog, I will put more NSO info to here, wish that will help more guys. The article will include more hands-on experiences, help beginner fast connect xr devices with nso by cli or netconf ned. For netcong NED, build by Pioneer at former, that need to manual exclude the Yang file that no support. In the article, will build netconf ned by native tool of NSO 5.2.0.
Platform Info
[root@nso opt]# ncs --version 5.2.0.1 [root@nso opt]# cat /etc/redhat-release CentOS Linux release 7.6.1810 (Core)

xrv9k-xr-6.6.3.14I version=6.6.3.14I [Boot image]
Install NSO
[root@nso nso-install]# bash nso-5.2.0.1.linux.x86_64.signed.bin [root@nso nso-install]# ./nso-5.2.0.1.linux.x86_64.installer.bin /opt/ncs-520 [root@nso nso-install]# cd .. [root@nso opt]# source ncs-520/ncsrc [root@nso opt]# ncs-setup --dest /opt/ncs-520-run [root@nso opt]# cd ncs-520-run/ [root@nso ncs-520-run]# ncs [root@nso nso-install]# ncs_cli -u admin -C admin connected from 10.125.6.211 using ssh on nso admin@ncs#
Put the ncsrc to bashrc:
[root@nso ~]# echo "source /opt/ncs-520/ncsrc" >> .bash_profile
Enable copy/paste of multi-line
Add follow config under of ncs.conf <cli>:
<space-completion><enabled>false</enabled></space-completion>
<ignore-leading-whitespace>true</ignore-leading-whitespace>
<auto-wizard><enabled>false</enabled></auto-wizard>
Then do package reload in NSO:
admin@ncs# packages reload
Add XRv9k and connect by by CLI NED
Add xrv9k, then commit
XR Version is 6.6.3 14i
Attention: xr 6.6.2 have an issu for “Cisco-IOS-XR-sysadmin-vm.yang” , so if you use 6.6.2, please exclude the yang when you build the netconf ned.
Cisco-IOS-XR-sysadmin-vm.yang has a violation of RFC 6087 YANG model guidelines, section 4.9. This will be corrected in future release.

Enable SSH/netconf-yang, and generate ssh key:

Then fetch ssh host key：
admin@ncs# devices device xrv9k-controller ssh fetch-host-keys
sync config from xrv9k:
admin@ncs# devices device xrv9k-controller sync-from
Build Yang NED by native tools in 5.2.x and change to Netconf NED
Change cli to netconf and enable yang project by native tools

Fetch Yang module and download

Building netconf ned and export:

Copy to package directory, untar file is ok:
[root@nso tmp]# mv -f ncs-5.2.0.1-xr-nc-6.6.tar.gz /opt/ncs-520-run/packages/ [root@nso tmp]# ls /opt/ncs-520-run/packages/ cisco-iosxr cn-to-dc dc-to-cn ncs-5.2.0.1-xr-nc-6.6.tar.gz rpl

Create a service module of python base
Will put detail info for custom service module at next article~ 🙂
