The 2012
edition of Cisco LIVE, scheduled to start Jan 30, 2012 at London, features some key players
in the networking business. With budget cuts & optimization of resources
being the buzzwords, businesses are vying to adopt the latest products to boost
their network performance & hence boost productivity.

NetFlow Analyzer from ManageEngine, is a product that supports a whole lot of technologies from Cisco and has evolved itself as an inevitable tool for network Administrators to gain in-depth visibility into their network. NetFlow Analyzer has aligned itself with Cisco in the following areas:
It is easily
the one product that has spread its wings into critical areas like QoS, SLA,
rich media traffic monitoring etc. and that makes it THE tool to deploy in your
network environment.

Source/Destination tab helps find the traffic from an individual host passing through a specific interface. The Source table will group all the source IP address in the conversation and the total traffic contributed by that host will be displayed. You can further drill down to an IP address/host to view the destination host with the application used and the amount of traffic transferred. This would be the same for Destination tab also.

Many customers have doubts regarding the IP that is shown as the top contributor under the conversations tab is not the top contributor in the Source/Destination tab. This is because, the conversations tab lists every conversation happened whereas the Source/Destination tab will group those conversations based on Source/Destination IP address. When grouping is done, the top IP in the conversation might have less traffic compared with the other IP address. So, combining the conversations results in traffic difference in this tab.

This tab accounts for the IN and OUT traffic of an interface separately. For example let’s assume there is traffic coming IN from the Internet to your LAN and you are monitoring your WAN Interface, the Source IN will be the public network IP Address and the Destination IN will be your LAN IP.
If traffic is from your LAN to the internet through WAN interface the Source OUT will be your LAN IP and the Destination OUT will be the internet IP.
Source/Destination Tab in IP Groups:
The function of these tabs will be the same but there will be no IN or OUT. This is because the accounting of traffic is different from the Interfaces. In a conversation if the destination IP address matches with the credentials for that IP Group, this conversation will be accounted as IN traffic for that IP groups. Similarly, if the Source IP matches it will be accounted as OUT traffic.
Therefore in the Source tab will be accounting the Source IP address from which the destination is contacted and the Destination tab will show the IP addresses to which the groups was trying to communicate.

Hope this helps.

Some frequently answered questions of the Application, Source and Destination tabs in NetFlow Analyzer have been handled in this blog.
Our primary focus would be on the ‘Applications’ tab which displays information on the applications used in the link along with the amount of data handled by that particular application and the bandwidth consumption involved.
NetFlow Analyzer maps the application on the basis of the port and protocol used in a conversation. Application mapping is done by prioritizing the lower port number used in a conversation. We cannot map the application name based on source/destination port number. For example,
Src IP Dst IP SrcPort DstPort Protocol
192.168.90.12 172.16.100.19 88 443 TCP
In the mentioned conversation, NetFlow Analyzer checks if any application has already been mapped for port 88 failing which it checks for the port 443 and maps under HTTPS.
Applications contributing more than 1KB of data is stored in the historic tables.
Why Application showing '_App'?
NetFlow Analyzer have 10000 Application names stored in its database. Any application that falls out of this category will be categorized as '_App', based on the protocol used.
This is why '*' is displayed for the port number in the ‘Conversation’ tab when the time period selected is more than 6 hours.
In such cases, clicking on show ports, based on which the corresponding application can be found and added through Application / QoS Mapping --> Add. The ‘Show Ports’ will be available within 24 hours of collection of data.

Why is the drilled amount of traffic less?
In some applications, the amount of
traffic shown in the Application tab on drilling down will be less.
This is because the drill down for an Application is queried from the
conversations table which stores the top 100 records of unique
conversations. If the conversation corresponding to a given
application does not fall in the top 100, then it will not be
displayed in the conversation table. This is exactly why the
discrepancy occurs.

Hope this helps.

With highly advanced technology development, the overhead on Network Administrators in ensuring prompt delivery of business critical applications over the WAN is very high. Video conferencing is predominantly taking place in major organizations for a variety of reasons like less cost, more productivity and a whole lot of advantages it can offer.
Video conferencing will take place between different branch
locations within the same country or over the WAN between different countries. A
Network Administrator needs to ensure smooth conferencing of video and avoid
undesirable factors such as delay, packet loss and jitter, which are most
likely to hamper the quality of the video.
In general, the Network Administrator would adjust bandwidth allocation in order to handle quality related issues for media rich traffic. With Cisco Medianet, this task has become really simple as the networks get intelligent enough on their own. To ensure effectiveness of the changes that have been made on the network.
Video traffic Quality Monitoring:-
Network Administrators can now easily configure their devices for video traffic monitoring through Medianet and Mediatrace reports of NetFlow Analyzer.
The illustration shows a video conferencing between 2 sites over WAN for about 4 hours, NetFlow Analyzer is used to monitor live video traffic between these 2 sites to know the performance over WAN.

Medianet and Mediatrace Report from NetFlow Analyzer:

We have not stopped with this, In our next release, you won't need to create monitors for Medianet and Mediatrace reporting. We have brought in a feature called On Demand report in which you specify the session details and continue monitoring the media rich traffic in real time basis.

The mood seems to be very light and happy. Its holiday season and
let us try to do away with the conventional things that we normally talk about.
It is that time of the year when we put an end to things and gear up for a
fresh start.
It is that time of the year when a lot of us introspect what we
wanted at the beginning of this year and how much of it has been achieved. This
kind of an analysis certainly helps in making our lives better. The bottomline
of all of this is that, we normally have the tendency to rely on the past and
plan for the future, the same way we generate ‘Capacity Planning’ reports in
NetFlow Analyzer.
Our networks are the way we made them and it is very natural to
draw some comparisons to real life. We have made them as a result of our
thinking and imagination. We are living at a time where geography is not a
barrier for business. It does not really matter where we are located, thanks to
the advent of telepresence and video calls. To ensure seamless
connectivity, the IPSLA module helps a great deal.
The Enterprises slowly but surely did away with the concept of
time. Had Einstein lived today, the true color of relativity would have been
right in front of him. When it is morning in the India centre, it is afternoon
in Hongkong office and midnight in the sales office in the US. Time does not
even matter for running business. It is an era of 24x7 working environment. No
matter what, the quality of service has to be maintained at least to the
minimum of standards for a ‘good’ from your management and the maximum for a ‘very
good’ and the optimum for a ‘fantastic’ (which never really happens). Our CBQoS reports try to make it happen for you so that your paycheck as a Network
Administrator goes up.
Just like we have a first aid kit at every place we are, be it our
car or office or home, to be prepared to face any anomalies of network health
is important. The security analytics reports help a great deal in this
direction.
These are simple real-life analogies to some key features of
NetFlow Analyzer. Clearly, they measure up to some important things in real life
that one cannot ignore. To overlook any of these aspects in either your network
or your life, could and would spell nothing but trouble.
So, it is now time to put to the best use, the resources you have
in life for a fruitful 2012 and exploit every feature in NetFlow Analyzer for a
smooth, healthy and an effective 2012 for your network.
Wishing all very happy holidays!
