Are there any good freeware monitoring applications which will enable engineers to determine data flow & possible impact SVI, interface and etc.

Here's another very capable NetFlow tool whose name I couldn't recall yesterday:

http://www.pmacct.org/

It's a NetFlow collector, not an analyzer. It can feed into reporting frontends such as this for visualizing the collected NetFlow data:

Here's the wiki:

Here're the config options I used on OS X. I didn't find the README.IPv6 file in the distribution though.

./configure --exec-prefix=/usr/local/pmacct \

--mandir=/usr/local/share/man \

--enable-64bit \

--enable-ipv6 \

--enable-v4-mapped \

--enable-threads \

--enable-mysql \
