Unable to load YANG file in a new NED

koushik331
Level 1
Level 1

Hi

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

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

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:

20-Jun-2017::16:37:03.537 Evaluating XPath for: /devices/device[name='BBTPN51J1R_PE4']/ned-settings:

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

exists("/ncs:devices/device{BBTPN51J1R_PE4}/device-type/cli") = true

get_elem("/ncs:devices/device{BBTPN51J1R_PE4}/device-type/cli/ned-id") = cisco-ios-xr-id:cisco-ios-xr

20-Jun-2017::16:45:39.378 Query(56): Starting evaluation of:

  ncs:devices/device[contains(name,'BBTPN51J1R_PE4')]

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

Thanks

Kiran

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

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#

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.

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

syntax error: incomplete path

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

Sent from my iPhone

Here is the NED zip.


Thanks

Kiran

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 ?

Possible completions:

  <WORD> - This system's network name (max 32 chars)

Glad it worked for you..

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

Thanks

Kiran

Try a make clean all...

I did that - but still no luck - not sure what I'm doing different...

[agrahki@nj51nsoc1v src]$ make clean all

rm -rf ncsc-out/* ../load-dir/* ncsc-out/*

rm -f ../jar/*.jar

rm -f java/src/com/tailf/packages/ned/hp/namespaces/*.java

cd java && ant clean

Phew - That finally worked!

Thanks for patiently helping with this!

You're welcome!
