Get all configuration below interface using python maapi

nso20 · ‎06-11-2020

Hello,

I can get the value of description on device interface using python maapi as below:

import ncs.maapi as maapi

with ncs.maapi.single_read_trans('admin', 'system', db=ncs.OPERATIONAL) as m:
root = ncs.maagic.get_root(m)

print(root.devices.device['mydevice'].config.ios__interface.GigabitEthernet['1'].description)

my_interface_desc

Instead of getting a single value, can I get the output of all configuration below the interface (e.g. description, ip address, negotiation, ...) using python maapi, something like:
root.ncs__devices.device['mydevice'].config.ios__interface.GigabitEthernet['1'].?

I do not believe you can get what you want in Python. What I can think about is the encodeXML() method in Java. This will return you the full sub-tree structure from your object that you can print in XML format (or decode at your wish). Please remember that a "config" in CDB is a tree and not a "string".

encodeXML
```
public List<ConfXMLParam> encodeXML()
                             throws NavuException
```
Description copied from class: NavuNode
Encoding the sub-tree including the current NavuNode as the topmost NavuNode to a ConfXMLParam array.
The returning ConfXMLParam array contains no values except for list keys. The leaf elements are encoded as ConfXMLParamLeaf therefore the returning array could be used as a input parameter to NavuNode.getValues(ConfXMLParam[]) on the current elements parent.
```
  NavuNode node = ...;
   //cxa contains structure that does not contains values except for
  //keys in list elements
   ConfXMLParam[] cxa = node.encodeXML().toArray(new ConfXMLParam[0]);
   NavuNode parent = node.getParent();

   //contains sub-tree with all the values
   ConfXMLParam[] cxb = parent.getValues(cxa);
 
```
Specified by:

encodeXML in class NavuNode

Returns:

An array of ConfXMLParam of the sub-tree (including key values) with key values.

Throws:

NavuException - If the operation could not be performed for some reasons
