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.
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.
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.
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.
Installation Process - Following
initial router or switch configuration, Netflow Monitor™ can
be installed in minutes.
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.
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.
What is Netflow
Cisco IOS® NetFlow technology
is an integral part of Cisco IOS Software that runs on the
majority of all Cisco networking devices. NetFlow collects
and measures data as it enters specific routers or switch
interfaces. By analyzing NetFlow data, a network manager can
identify the cause of congestion; determine the class of service
(CoS) for each user and application; and identify the source
and destination network for your traffic. NetFlow allows extremely
granular and accurate traffic measurements and high-level
aggregated traffic collection. Because it is part of Cisco
IOS Software, NetFlow enables Cisco product-based networks
to perform IP traffic flow analysis without purchasing custom
probes--making traffic analysis economical on large IP networks.
NetFlow and Quality of Service (QoS)
NetFlow™ does not accelerate
QoS services such as traffic classification or Committed Access
Rate (CAR). Note that NetFlow™ itself is not a QoS feature;
it simply captures the Quality of Service level of each flow
does not require adoption of new or proprietary protocols
or new generations of networking equipment. NetFlow™ is
available today on most Cisco platforms.
may be deployed incrementally, on an interface-by-interface
basis on strategically located edge, aggregation or WAN
data collection and export will also serve as a key enabler
for flexible, differentiated IP services based on Cisco
IOS QoS capabilities.
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
requirement of Pentium III, 256MB Ram, 10GB Hard Disk,
Windows NT/ 2000/ XP. This specification will increase
based on number of devices monitored.
Note that NetFlow Monitor
should not be installed on the same machine as NetWatch.
Crannog Netflow Monitor is available to download and
run in evaluation mode for 4 hours.
