Hi,
Please consider the following L2VPN schema tree.

container l2vpn
container instances
list instance
leaf name
. . . . . . . .
case redundancy-grp
list primary-pw
leaf name
list backup-pw ---------> How to access Primary-pw here ?
leaf name
leaf protection-mode
leaf revert
leaf revert-delay
leaf split-horizon-group

In this schema tree, I would like to get primary-pw name in backup-pw SIL. I could access the primary-pw name from OpenYuma-DB after "commit" phase. But, I need to access primary-pw name in validation phase itself. So, i can't get it from OpenYuma-DB. Could you please let me know if there is any other way ?
Thanks,

Hi Vladimir,

This is regarding accessing all elements in a list in yuma123 without using index.

I knew, a particular element can be accessed using index/key in a list in yuma123.
There is a situation where i dont know the index but want to access all elements from the list.
So, how can i access all elements from the list. Is it possible ? If so, can you please let me know.

Basically, how to access all elements in the list.

Thanks in advance.

Hi,

I want to access data from one container to another in OpenYuma code. How can I do ?
Container Peer-1
|
|
list of sub-containers (Say A, B, C, D)
|
|
leaf state;

Question 1: From SIL of A.leaf , can we access B.leaf ? If so, how can access ?
Question 2: Can I achieve the above using XML config? Or XML config used only for SET functions ? Can't be used for GET ?
Question 3: If I create another container say, Peer-2, can it access data of Container-1 say, we want to access Peer1.A.leaf ? If so, how can we access ?

Thanks,
Kaliyaperumal K

Hello vladimir, I hope you are doing well,
We are begginers in all what concern yuma and yang module creation, we followed your wiki to create a client with yangcli and agent with netconfd and loaded the toaster module . The tutorial was sucessful in a sens that we had RPC OK in each of the tutorial steps .
Then we created our own module based on the toaster one, but we didn't know in which folder should we put our new created file.
We did a little bit of searching and we find that the modules were in a folder "/usr/share/yuma/modules/netconfcentral" we dropped our new module in this folder, and executed the netconfd command : "/usr/sbin/netconfd --module=rhode-and-schwarz --superuser = minanas" and then we get the following error :

Hi,

I am using candidate and running database.

When I do commit for my config in yangcli, due to some error config I am getting operation failed.
After that, I am configuring with correct values and committing again. At this time I am facing malloc-failed issue continuously for all commits.
due to that, I am not able to proceed with commits. Could please help me on this issue.

we are using openyuma 2.2 version. we are planning to upgrade. before that, we want to fix this issue.

Regards,
Santhosh

Vladimir Vassilev and everyone, could you take a look at the issue? Thanks.

Hi,

I'm trying to build yuma123, however I get this error message when I run the instruction $make:

ietf-network-bridge-openflow.c:31:10: fatal error: openvswitch/vconn.h: No such file or directory
#include <openvswitch/vconn.h>

I cloned this project which includes the required file and directory: https://github.com/openvswitch/ovs

But I still get the same error even though I explicitly included it in CLI ($make -I/ROUTE_TO_OPENVSWITCH/). I've also tried including this route in the Makefile but I'm not sure if I'm doing it okay.

Could someone help me?

Hi,
I am new to yuma123 from the user perspective.
I have 2 questions:

1/
I would like to integrate the yuma123 NETCONF server implementation into my application module, such that it runs from the integrated application threads/process.

Essentially, I am exploring options to NOT run as a daemon process, but as a library of the application.
For example, integrate integrate the "IO server loop for the ncxserver socket" (agt_ncxserver_run) of the yuma123 NETCONF into the application.

Is this approach reasonable?

2/
I would the user applications to know which attribute(s) have changed when the running configuration has changed, or the candidate configuration has been committed.

At present, my understanding is that that NETCONF server shall write the latest configuration into a 'xml' file. And, a mechanism needs to exist to inform the user application (eg. SIGHUP or alternate mechanisms). The user application needs to "diff" the running version from the new version of configuration and apply it.

The above works good for user application which can afford to restart. However, for applications with dynamic updates, the precise attribute(s) which have changed needs to be known.

Would u help how this would be possible?

Thanx.
Shashank

Hello,
In our system we need to do some extra validation and pre-commit processing that requires asynchronous communication with the target components. Is it possible to use the async validation callbacks and what would be the best way to achieve this?

But e.g. the accompanying libhelloworld.so for https://github.com/vlvassilev/yuma123/blob/master/example-modules/helloworld/helloworld.yang is included:

> dpkg -S helloworld
netconfd: /usr/lib/x86_64-linux-gnu/yuma/libhelloworld.so.0.0.0
netconfd: /usr/lib/x86_64-linux-gnu/yuma/libhelloworld.so.0
netconfd: /usr/lib/x86_64-linux-gnu/yuma/libhelloworld.so

So helloworld.yang and other example modules should also be packaged accordingly

Hi,

I want to merge multiple modules libraries into the single library. let say, interface.so, pw.so, l2vpn.so. PHB.so etc.. all these modules I want to load using the single ".so" file.

I am calling other module function from one module, since both the modules having different ".so" files, while loading the module I am getting undefined reference to .

could you please share your valuable suggestion.

We want to know how the yang module is working and where the yang information is stored.
Like i want to register the virtual node for read only leaf in yang.
How we can identify the type and walk all the leaf node and register the virtual node CB at the time of loading the module.

Hi Vladimir,

Could you please let me know how redundancy could be supported for OpenYuma DBs such as startup-config.DB, Candidate-config.DB and Running-config.DB ?

Thanks,
Kals

I am testing a very simple construct to verify behavior of "when" in augment.
In the toaster.yang model I added these 2 leaves on the top level:

	leaf toasterWeight {
	    type int32 {
            	range "1 .. 10"; 
	    }
 	    config true;
	    default 5;
	}
        leaf aug-test-leaf {
          when "../toasterWeight = '10'";
             config true;
             type string;
	     default "fooo";
          }

aug-test-leaf behaves as expected: set in DB if toasterWeight =10. Otherwise it's not set in DB, even so yangcli reported success (I guess this is a separate issue).

I created another module with augment as following:
```
module augment-test3-when {
       yang-version 1.1;
       namespace "http://netconfcentral.org/ns/augment-test3-when";
       prefix mymod3;

       import toaster {
         prefix toast;
       }
     augment "/toast:toaster" {	  
          leaf mandatory-leaf {
          when "../toast:toasterWeight = '5'";
             config true;
             type string;
	     default "bla";
          }
       }
``` 
I've loaded this module. It looks like the when statement does not have any affect.
I can create mandatory-leaf when toasterWeight = 10

```
rpc-reply {
  data {
    toaster {
      toasterWeight 10
      mandatory-leaf bla
    }
  }
}
```
I also experimented to put when statement at the augment level: ( when "toast:toasterWeight = '5'";) - it does not work either. 

Please advise.

Regards,

I got above error when i added yangdiff and yangdump compilation in Makefile.am. it seems fields are not there. But when i commented where ever it is used, it started compiling. and i got binaries. But i want to make sure is it ok or not, since i haven't gone through whole code so i am raising a issue.

Hi vlvassilev,

Would like to know how dependency among attributes are handled in yuma123 ?

I see, each attribute has its own SIL function to be programmed into hardware. Assume the following scenario. A object has to be created with 3 attributes such as A1, A2 and A3.
A1 is an optional attribute where as A2 and A3 are mandatory. Now, object creation SIL function has been called with A1. It can't be programmed without A2 and A3. But, A2 and A3 edit SIL functions (for creating them) are not called hence they are not programmed in the hardware so those values are not available. How to handle this situation on yuma123 ?
Assume, A2 and A3 can't use default values as once the values are written on the hardware can't be reprogrammed.

Could you please let me know your thoughts on this ?

Thanks,
Kals

Upon trying to connect from yangcli to netconfd, the messages I get:

What might be going wrong?

Hi. all
I saw an issue upon netconf get operation in your yuma123 package.
Another yang-library capability is being appended to netconf-state capabilities after get operation.
Please, check cap_update_yang_library_val() function.
It seems to work well after the following fixing.

status_t
    cap_update_yang_library_val (val_value_t *caplist,
                        const xmlChar *revision,
                        const xmlChar *module_set_id)
{
    char* prefix = "urn:ietf:params:netconf:capability:yang-library:1.0";
    int prefixlen = strlen(prefix);
    val_value_t* childval = NULL;
    for (childval = val_get_first_child(caplist);
        childval != NULL;
        childval = val_get_next_child(childval)) {
        if(strlen(VAL_STRING(childval))<prefixlen) {
            continue;
        }    
        if(0==memcmp(prefix,VAL_STRING(childval),strlen(prefix))) {
            break;
        }    
    }    
    if(childval)
    {    
        val_remove_child(childval);
        val_free_value(childval);
    }    
    return cap_add_yang_library_val (caplist, revision, module_set_id);
}  /* cap_update_yang_library_val */

Hello,

1. I am having troubles to find a function (API) to get value from DB by XPATH from my callback function.
   I believe I saw API that looked something like this:
   const val_value_t *
   agt_val_get_data (ncx_cfg_t cfgid,
   const xmlChar *defpath,
   status_t *retres);
   But I could not find it in the latest code.

2. I will also need an API to access value of parameter in the incoming message for validation reason. Can I use the following function for this purpose?
   /********************************************************************

• FUNCTION agt_get_parmval
• Get the identified val_value_t for a given parameter
• Used for error purposes!
• INPUTS:
• parmname == parameter to get
• msg == incoming rpc_msg_t in progress
• RETURNS:
• status
  *********************************************************************/
  extern const val_value_t *
  agt_get_parmval (const xmlChar *parmname,
  rpc_msg_t *msg);

Hi @vlvassilev

While creating https://github.com/userzimmermann/yuma123-docker-images/blob/master/yangcli/Dockerfile - which also uses http://yuma123.org/repos/apt/debian to install yangcli - I figured out two things:

• By adding --no-install-recommends to apt-get -y install software-properties-common you can save up to 100MB of installed package data
• Minimal Debian installations don't necessarily have wget and gnupg (needed for apt-key) installed. You could add those two packages to the first apt-get install command

There is no ./yuma123-git/autoreconf script.
There is no ./yuma123-git/configure script.
Here comes the question - how the heck to build this package???

Hi Vladimir,

What would be the problem, in case if startup-config-db and running-config-db are same always i.e whenever there is a change on running-db would be saved in startup-db also. So, will there be any problem due to this approach ?

Actually, i am seeing one problem here... in case if the node is crashed due to mis-configuration, it might go for continuous crash as startup-db and running-db is same. Assume, the mis-configuration has already been saved in running-db and would have been saved in startup-db.

Please let me know if you see any other problem apart from the above ?

Thanks,
Kals

hi, vlvassilev.
Could you check this update for get-schema.

https://github.com/neoul/yuma123/commit/2d5ecce8a1d565c9005981e2ca426792a00706cf

The current yuma123 doesn't support the query for submodule schema file via get-schema rpc.
But, according to RFC 6022, the submodules should be also retrieved by get-schema and netconf-state/schema path.

Hi,

Configuring object is leafref, the reference object is configured already in same module.

rpc-reply {
rpc-error {
error-type application
error-tag unknown-namespace
error-severity error
error-app-tag data-invalid
error-path /bridge-mib:BRIDGE-MIB/bridge-mib:fsQBridgeMIBObjects/bridge-mib:fsDot1qTp/bridge-mib:fsDot1qFdbTable/bridge-mib:fsDot1qFdbEntry[bridge-mib:fsDot1qVlanContextId='0'][bridge-mib:fsDot1qFdbId='12']/bridge-mib:fsDot1qVlanContextId
error-message 'unknown namespace'
error-info {
error-number 266
}
}
}

reference object leaf contains " smiv2:max-access "not-accessible" "will it affect?

Thanks,

Hi,

Below l2vpn augment is doing from "qos.yang", SIL code is not generating for "ingress-qos-template" grouping in both l2vpn and qos modules using make_sil_dir.

augment "/l2vpn:l2vpn/l2vpn:instances/l2vpn:instance/l2vpn:endpoint/l2vpn:ac-or-pw-or-redundancy-grp/l2vpn:ac"
{
uses ingress-qos-template;
}

Could you please let us know, SIL code will not be generated for augments?

Hi,

I am using 2.11 yuma123, yuma directory is not getting created with make and make install of 2.11 yuma123. Earlier I was using 2.2 openyuma where /etc/yuma/ directory is getting created.

I want to load the modules using netconfd.conf file. This implementation is removed from latest yuma123?
Do we need to create that directory manually?

Thanks & Regards,
Santhosh

Hi,

We know how to access Read-Only container elements, Is there any API to access Read-Write list elements without using the index.

I have referred mod_yangrpc_example.c file but here you are accessing Read-only elements. can you please let us know is there any way to access the list elements (Read-write).

Thanks,
Santhosh

Hi,

The issue treated here is about the development of a C module which allows yuma/netconfd to interact with a system's routing interface. The yang module it will be developed upon is "[email protected]" [https://tools.ietf.org/html/rfc8349#].

Hi

I am working on a project for my university where I basically have to create a Mininet network and manage it through the NETCONF protocol.
I have chosen to run the yuma server (netconfd) in the nodes and I have not yet decided whether I will use OpenDayLight or ONOS as the controller.

My question is as follows:

After editting the running configuration and committing it... Does it really change the device configuration? i.e. let's say I configure a new route. Would this route be added to the device or is there any other action required after committing?

I ask this since I've read about SIL functions in the documentation and I'm not sure whether the commit operation is enough or if there is needed any other further action in order to truly affect the device's configuration.

Regards, Victor.

Hi vlvassilev,

Could you please let me know how many threads are supported in OpenYuma123 and how to check it out ?

As per my understanding, I could see that only one thread is supported by yuma123 frameworks.
But, am just wondering how a single thread manages all such as configuration, notification, polling and etc. Could you please elaborate a bit on how all these are managed ? In case if a thread is busy on configuration then it cant send notification. Isn't it ?

Thanks,
Kals

Added the identical-identity-names yangcli testcase that currently fails. The user should be prompted to enter fully specified name e.g. module:identity to resolve the conflict.

Hi,

Am seeing transaction-id is also stored as storing startup-db.

1. I would like to know what is the use of storing it ?
2. Is it possible to replay the config based on the transaction id when system comes up ?

Does running-db also would store the transaction-id ?

Thanks,
Kals

Hi vlvassilev,

I have below query.

Is yuma123 supported with multithreading(lock,unlock) ?
Is it possible to create multiple threads of yuma123? are the shared memory handled properly ?

Thanks in advance.

Sivaraman G

The problem is reproduced with the following testcase: https://github.com/vlvassilev/yuma123/tree/6daf58f1ba08207e67be0762a1f59f50e40d9c86/netconf/test/netconfd/identityref-typedef

Hi,

I am generating SIL code for my code, it is having Union leaf as key. But in SIL code generation for all other types typecasting happening except UNION types. Please find below piece of code.

const xmlChar *k_mplstp_oam_meg_meg_name = VAL_STRING(agt_get_key_value(errorval, &lastkey));
uint32 k_mplstp_oam_meg_lsp_spme_tunnel_id = VAL_UINT(agt_get_key_value(errorval, &lastkey));
xmlChar *k_mplstp_oam_meg_lsp_spme_local_lsr_id = agt_get_key_value(errorval, &lastkey); ->UNION
xmlChar *k_mplstp_oam_meg_lsp_spme_remote_lsr_id = agt_get_key_value(errorval, &lastkey); ->UNION

I have checked in netconf/src/ydump code, found below check,
boolean notunion = (obj_get_basetype(obj) != NCX_BT_UNION);
........
if (notunion) {
write_c_val_macro_type(parms->scb, obj);
ses_putchar(parms->scb, '(');
}

May I know the reason why typecasting not doing for Union.

Can I remove "notunion" check, if I remove, wil I get any error?

Hi,

I have installed a different version of both yuma123_2_10 and openyuma-master_2.3in one linux machine. after installing both, I have observed few yang files are duplicated. Same yang files are present in /usr/share/yuma/modules/netconfcentral/ and /usr/share/yuma/modules/yuma123/ folder. Due to this, the netconf server is not starting.
As per my understanding, the openyuma-master_2.3 package installing some dependent yangs in netconfcentral folder but the same yangs are installed by yuma123_2_10 package in /usr/share/yuma/modules/yuma123/
is this understanding correct?

Hello Vladimir,

Yuma123 not creating make_sil_dir . I followed below steps . Yangcli ,Yangdump , netconfd get installed but make_sil_dir not created. To get install make_sil_dir what is the steps ?

===Option 2: Build from source===
sudo apt-get install git autoconf gcc libtool libxml2-dev libssh2-1-dev make libncurses5-dev zlib1g-dev libreadline-dev

git clone git://git.code.sf.net/p/yuma123/git yuma123-git

Hi vlvassilev,

1. Will copy-config from any source (startup-config-db or candidate-config-db) to running-config-db would lead to reprogramming the hardware ?

running-config-db would be updated once config is programmed into the hardware through calling SIL functions. If configs are copied from startup-config-db to running-config-db then all the configs on running-db would be erased i.e would it call SIL functions to delete all the config ? then, as part of copy-config, would program the config into hardware through SIL functions ? This might lead to reprogramming some of the config into the hardware. is nt it ?

2. Assume a situation where I have some config on candidate-db without commit i.e. the configuration changes are not yet committed into running-db. If i do copy-db from candidate to running-db, will those uncommitted configs also would be copied to running-db ?

Thanks in advance,
kals

Hello,

It looks like Yuma 123 Wiki has not been working for the last few days:
http://yuma123.org/wiki/ shows the following error message:

Yuma123 Wiki has a problem
Sorry! This site is experiencing technical difficulties.
Try waiting a few minutes and reloading.

(Can't contact the database server: Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2) (localhost))

Hi,

I have downloaded 2.11 version yuma123, and followed steps are per the README and compiled.
I have started netconfd and connected to yangcli session and load one module and SIL code.
When I tried to configure something using I am facing below error.

**Getting yang-library module set ...

Hi,

What is the Reason for pattern match failed while loading module?
yangcli root@localhost> mgrload IEEE8023-LAG-MIB

Hi,

Everytime I try to connect to the netconfd server from yangcli I will get the message "session shut by remote peer" at yangcli logs, I can't start no session.

However, I can properly SSH to port 830 so it's not a configuration issue (sshd_config has been changed according to the wiki).

Any clue on this?

Hi,

1. Is it possible for other Northbound Interfaces such as CLI, SNMP can alter the config which was programmed by Netconf ?

2. If so, would the controller be notified for the configuration changes ?

Thanks,
kals

what is the detail of create-subcsription with parameter filter for subtree and xpath for example below:
1/create-subscription stream=NETCONF startTime=2017-09-18T00:01:00+07:00 'filter type="subtree"'=222
2/create-subscription stream=NETCONF startTime=2017-09-18T00:01:00+07:00 'filter type="xpath" select="/myService/config and (port=333 or homeLocation=dangle)"'

Does we have test case for the parameter of filter in create-subscription? thanks.
