In continuation to Cisco Medianet Introduction blog, This
blog explains the configuration of Cisco routers to export Medianet related
information . In the latest IOS version,
Cisco adds Performance Monitor parameter to its NetFlow export. So, with
NetFlow traffic analysis, we gain bandwidth monitoring and performance monitor
of business critical application.
Cisco Performance Monitor:-
The performance impact on business critical application on
the network is due to the following parameters jitter, latency, packet loss, low RTT. The Cisco Performance Monitor will
help to monitor Jitter, Latency, Packet Loss and RTT for each flow packets
exported from the router.
Performance Monitoring is important for Video traffic
because the delivery of LIVE video should be with high definition and zero
delay. As mentioned in the earlier post, voice & video traffic would
quadruple by the end of 2012. So, video traffic should be given high priority
when it comes to quality and performance.
Cisco Medianet in NetFlow Analyzer :-
This feature helps you to monitor and analyze voice, video
and data traffic and report on loss, latency and jitter thereby helping you
optimize rich media applications. NetFlow Analyzer uses this feature of Cisco’s
Medianet to report on the rich media traffic. It makes you aware of the volume
and quality of media traffic in your network bandwidth. NetFlow Analyzer
reports on the volume of media traffic, round trip time, packet loss and jitter
along with the source, destination or application that is responsible for media
traffic. These reports help you isolate network issues with regard to rich
media applications and determine the quality of media traffic.
Prerequisite:-
- The Device
should run Cisco IOS which supports Cisco Performance Monitor
IOS version :- 12.4(13r)T or above
Software
Version :- 15.1(3)T or above.
- IPv4
Traffic
- The
networking device must be configured for IPv4 routing. - Cisco
Express Forwarding or distributed Cisco Express Forwarding must be enabled on
your router and on any interfaces on which you want to enable Cisco Performance
Monitor.
Configuring Cisco Performance Monitor:-
The configuration for Cisco Performance Monitor is quite
similar to Flexible NetFlow configuration. This involves following steps:
- Configuring
Flow Exporter - Configuring
Flow Record - Configuring
Flow Monitor - Creating
Class - Creating
Policy for performance monitor - Attaching
the policy to monitored interfaces
Flow Exporter Configuration:-
The flow exporter defines the destination to which NetFlow
packets has to exported.
flow exporter ManageEngine
destination 192.0.2.1 // NetFlow Analyzer listener
port
source FastEhternet0/0
transport udp 9996 // Default listener port for
NetFlow Analyzer
version 9
option exporter-stats timeout 60
template data timeout 60
Flow Record Configuration:-
Here we are going to define records that corresponds to
Performance and regular Flexible NetFlow fields.
flow record ManageEngine
match ipv4 protocol
match ipv4 source address
match ipv4 destination address
match transport source-port
match transport destination-port
collect routing forwarding-status
collect ipv4 dscp
collect ipv4 ttl
collect ipv4 source mask
collect ipv4 destination mask
collect transport packets expected counter
collect transport packets lost counter
collect transport packets lost rate
collect transport round-trip-time
collect transport event packet-loss counter
collect transport rtp jitter mean
collect transport rtp jitter minimum
collect transport rtp jitter maximum
collect interface input
collector interface output
collect counter bytes
collect counter packets
collect timestamp interval
collect application media bytes counter
collect application media bytes rate
collect application media packets counter
collect application media packets rate
collect application media event
collect monitor event
Flow Monitor Configuration :-
A flow monitor is the one that caches all the traffic
passing through the applied interface and the flow exporter will export all the
traffic as UDP datagram to NetFlow Analyzer server.
flow monitor ManageEngine
description Ipv4Monitor
exporter ManageEngine
record ManageEngine
timeout active 60
timeout inactive 60
Flow Class Creation :-
A Class is the one which specifies the filter that
determines which flow traffic to monitor.
Class-map ManageEngine
match any
Policy Creation for Performance Monitor:
Policy creation for Performance Monitor is shown below.
Router(Config)#policy-map type performance-monitor
ManageEngine
Router(config-pmap)#class ManageEngine
Router(config-pmap-c)#Flow monitor ManageEngine
Router(config-pmap-C)#monitor metric rtp
Router(config-pmap-c-mrtp) clock-rate 8 9600
Router(config-pmap-c-mrtp) max-dropout 2
Router(config-pmap-c-mrtp) max-reorder 4
Router(config-pmap-c-mrtp)# min-sequential 2
Router(config-pmap-c-mrtp)# ssrc maximum 20
Router(config-pmap-c)# monitor parameters
Router(config-pmap-c-mparam)# flows 40
Router(config-pmap-c-mparam)# history 4
Router(config-pmap-c-mparam)# timeout 20
Router(config-pmap-c)# react 41 rtp-jitter-average
Attaching the Policy to Interface:-
The created policy is now been attached to an interface
for performance monitoring:
interface FastEhternet0/0
service-policy type performance-monitor input
ManageEngine
You can verify the policy applied details by running
following command:
show policy-map type performance-monitor interface
FastEthernet0/0
Once the router is configured as mentioned above, You are
ready to monitor device for Cisco Medianet.
We will explain about each report generated by Cisco Medinet in our next
blog.
