Unable to load YANG file in a new NED

koushik331 — Fri, 01 Mar 2019 11:52:23 GMT

I'm experimenting with a NED and wrote a simple YANG file to model just the sysName of a HP device.

However, I can't get the YANG file loaded. Here is what I see:

admin@ncs# devices device hp-5900 check-yang-modules verbose

module {

name hp-5900

status unknown <---------

}

Does anybody know how to debug further?

Thanks

Kiran

Anything if you check the status of the packages in the CLI (show packages)?

Anything in logs/devel.log or logs/ncs-java-vm.log?

Nothing interesting in “show packages”:

packages package hp-5900

package-version 3.0.1

description "NED package for the HP 5930"

ncs-min-version

directory /var/opt/ncs/state/packages-in-use/1/hp-5900

component hp-5900

ned cli ned-id hp-5900

ned cli java-class-name com.tailf.packages.ned.hp.HpNedCli

ned device vendor hp

NAME VALUE

Something interesting on Xpath.trace:

../ncs:device-type/ncs:cli/ncs:ned-id = 'cisco-ios-xr-id:cisco-ios-xr'

Why is it trying to look for cisco-ios when searching for hp-5900?

Thanks

Looking at my system, I also see this.. but the (IOS) NED is functional.... what is the actual issue you experience?

Re: Unable to load YANG file in a new NED

koushik331 — Wed, 21 Jun 2017 16:22:50 GMT

I'm unable to configure the HP through NSO:

devices device hp-5900 check-yang-modules verbose

module {

name hp-5900

status unknown

}

admin@ncs#

admin@ncs# devices device hp-5900 config sysname

-----------------------------------------^

syntax error: incomplete path

admin@ncs# devices device hp-5900 config <------- I can't type "?" here and nothing works.

Can you please zip up the NED and I can take a look?

Works for me.

Please note that you have an error in your netsim/Makefile, it still references the original NED, which leads me to ask, did you ever rebuild the entire NED?

admin@ncs# show packages package oper-status | notab

packages package hp-5900

oper-status up

admin@ncs(config)# devices device hp config hp:sysname ?

koushik331 — Thu, 22 Jun 2017 12:23:33 GMT

Glad it worked for you..

I just did a "make all" in the src directory to rebuild the NED. Is that not sufficient?

Thanks

Try a make clean all...

You're not in config mode in NSO...
