Please consult the documentation for child elements on any API. Documentation can be found at the NetApp Developer Page.
If you make a configuration change and want to keep it persistent, make the change using the appropriate net- API. Then use net-config-get-active and take net-config-info output and use it as input to net-config-set-persistent.
I would like add that I would start off by saving a copy of the .rc file, and then execute the set persistent code and compare .rc files. After that, make one change in the active configuration, set persistent and compare the changes. Keep it simple at first for testing.
Thanks Rick I am referring to the ZEDI engine you suggested. Based on the information in that I have created this code. However I am noticing that when I run this code on my 8.2 7 mode Ontap simulator the Simulator crashes , something funny somewhere .
There is no other way of approaching ifgrp-info to create a ifgrp except persistent api .Please let me know if there is a better solution than this .
