Enable TRACE for VIPTELA_PLUGIN to see every occurrence

Cause

No subnet mask information is set in the information returned for a given IP Address.

Environment

All supported DX NetOps Virtual Network Assurance (VNA) releases r21.2.4 and older

Resolution

This is being addressed by defect DE516719. A resolution is expected to be included in the r21.2.5 release. That is subject to change and is just an ETA.

The solution will be to bypass the parsing logic code for any IP Address returned without subnet mask details.
