VMware Aria Operations for Networks 6.14

Cause

Juniper OS version higher than 20.2, uses higher netconf juniper library that is incompatible with our netconf juniper library for parsing data. 

Resolution

A patch will be delivered later this year with the new library. Alternatively, you can open a Broadcom Support case and we will work with engineering for a workaround.
