Cisco NetFlow services consist of
high-performance IP switching features that capture a rich set of traffic
statistics exported from Cisco routers and switches while they perform their
switching functions. NetFlow traffic statistics include per-user, per-protocol,
per-port, and per-type of service statistics. These statistics can be used by
Network Managers for a wide variety of purposes, such as network analysis and
planning. Web based graphical information is presented to the user showing
statistics on elements such as source/destination, 'top talkers', protocol types
and protocol load on the network. Individual NetFlow monitors would be installed
at each network site where these statistics are required.

Product Benefits:-
1. LAN and WAN Bandwidth analysis without
hardware probes - Offering an intuitive "drill down" into bandwidth
utilisation without the complication and expense of hardware probes.
2. Completely Web-based - providing
all authorised network users with access to information, which is relevant to
them.
3. Integration With Crannog Netwatch™
- Netwatch™ complements Netflow Monitor™ by providing a customisable unified
screen displaying network health and link status and providing an "in context"
view of Netflow Monitoring.
4. Simple and Intuitive Graphical Format
- which converts complex data into a clear view of bandwidth utilisation
expressed as bytes transferred and percent utilization , all data accessed from
a simple historical bandwidth graph.
5. Cost-effective Solution - unlike
many other network management solutions which offer Cisco Netflow analysis,
Netflow Monitor™ will run as a stand alone tool and does not require an
expensive initial investment.
6. Windows Based - Netflow Monitor™ is
ideal for deployment to all businesses requiring bandwidth analysis, based upon
an NT4/2000/XP platform, it is simple to administrate and does not require the
UNIX skills often associated with high end Netflow analysers.
7. Speedy Installation Process -
Following initial router or switch configuration, Netflow Monitor™ can be
installed in minutes.
8. Huge Potential Install Base - Cisco
IP™ software supports Netflow statistical analysis in almost all routers and
chassis-based layer 3 switches. Netflow Monitor™ effectively leverages the value
of Cisco IOS™ and presents your sales team with a huge potential customer base.
It should be noted
that Cisco Netflow data generation must be specifically enabled on each
nominated Cisco router or switch. Netflow data generation requires specific
Cisco IOS versions and configurations on the device in question. Depending on
equipment specification additional memory may also be required for each device.
Netwatch™ - NetFlow Monitor™
will run for four hours in evaluation mode before terminating. If you require a
longer evaluation period, contact
sales@nmcnetworking.com for an evaluation key.
Key Points.
·
NetFlow™ does not require adoption of new or proprietary
protocols or new generations of networking equipment. NetFlow™ is available
today on most Cisco platforms.
·
NetFlow™ may be deployed incrementally, on an interface-by-interface basis on
strategically located edge, aggregation or WAN access routers.
·
NetFlow™ data collection and export will also serve as a key enabler for
flexible, differentiated IP services based on Cisco IOS QoS capabilities.
·
Crannog's NetFlow Monitor provides a commercially supported and cost effective
solution to collect flow export data. Allowing users to perform real time and
post-processing of statistics, providing storage and making flow detail records
available to consumer applications in a convenient format
NetFlow Monitor
V1.4 has been tested in accordance with interoperability criteria set by Cisco
Systems, Inc. and is compatible with Cisco IOs Software - NetFlow. For full

Key
differences between NetFlow Monitor and NetFlow Tracker:
1.
Tracker stores ALL NetFlow data so it
will save a complete record of all traffic that traverses your network for up to
a week. After that it can be archived off to a separate database for retrieval
as required.
2. Tracker presents its data in 1
minute intervals, as opposed to 10 minutes in Monitor.
3. Tracker can output all its data in
.csv if required for reporting purposes.
4. Tracker has no memory limitation so
theoretically a single copy can handle NetFlow data from an unlimited amount of
devices.
5. Tracker reports on packet as well
as traffic levels so its extremely useful from a SECURITY perspective for
identifying 'rogue' devices, devices infected with viruses or devices that may
represent a security breach.
