Network Mapping helps you identify the problem’s origin quickly. Lets you
spot the dependant devices/ affect business service that helps you prioritize
the event based on the impact and urgency.

9. Network Mapping in OpManager
9
• Automatic Layer2/ Layer 3 Network mapping
• Custom device grouping
• Traffic weather map

10. Network Mapping in OpManager
10
• Automatic Layer2/ Layer 3 Network mapping
Automatic L2/ L3 Network Mapping uses CDP & Bridge MIB and Reads ARP
cache to plot your complete network diagram. You can also export the
network diagrams to Microsoft Visio in a click.

11. Network Mapping in OpManager
11
• Custom device grouping (Business views)
Business view or Custom device groups is a widely used OpManager
functionality that helps admins to group devices based on the business
service they cater to or by physical location of the device or based on
logical representation of the network.

12. Network Mapping in OpManager
12
• Traffic weather map
Traffic weather map helps you locate the highly utilized link in a particular
Business view. You can drill down to the device or the link directly by clicking
on the link from this view.

13. Bandwidth / Traffic

14. Bandwidth or Traffic monitoring in OpManager
14
Interface snapshot page showing the last Traffic received and transmitted details,
Interface details, Additional Fields, Interface availability info, Today’s Traffic usage
trend, Errors/ Discards, Total bytes transferred or received and Packets Per second
for every monitored interface. Inset: Real-Time Traffic utilization graph

15. Bandwidth/ Traffic : Traffic Analysis module
• An unusual bandwidth spike, makes you question so
many things like...
– Who is using the bandwidth?
– Which applications (ports & protocols) are using the
bandwidth?
– Is it a legitimate business traffic?
– Do we need to upgrade the link? & more…
Cisco’s NetFlow gives you the right insight you need on your bandwidth
15

16. Bandwidth/ Traffic : Cisco’s NetFlow
• Cisco’s NetFlow give you
– Source IP address
– Destination IP address
– Source port for UDP or TCP, 0 for
other protocols
– Destination port for UDP or TCP,
type and code for ICMP, or 0 for
other protocols
– IP protocol
– Ingress interface (SNMP ifIndex)
– IP Type of Service
Vendors such as 3com, Adtran, Extreme started supporting NetFlow as well.
Similar to Cisco’s NetFlow HP, Juniper and other vendors start creating their
own type of flows such as sFlow, j-Flow, IP FIX & more…

17. Bandwidth/ Traffic Analysis using NetFlow plug-in
• NetFlow Traffic Analysis module, lets you know
– Which user occupies your bandwidth
– What is the top conversation happening in the link
– Which application consume most of the bandwidth. Is it a
business traffic or an user in the back-office streaming a
video.

Root cause Solution

19. Bandwidth/ Traffic Analysis using NetFlow plug-in
• Network Based Application Recognition – NBAR
– An intelligent classification engine to identify dynamic port
applications traffic usage.
– Identifies 70+ dynamic port applications (web-based or client/
server apps)
• www.netflowanalyzer.com/help/nbar/nbar-supported-applications.html
– Bundled as a part of Cisco IOS
– Need to enable NBAR option on the interface
19

20. Bandwidth/ Traffic Analysis using NetFlow plug-in
• Class Based Quality of Service – CB QoS
– Provides information about the QoS policies applied and
class-based traffic patterns. Helps you qualify the QoS
policies set on the router.
– Bundled as a part of Cisco IOS 12.4(4)T and above
– Information are retrieved using SNMP in OpManager
20

21. Monitoring Faulty Components
21

22. Monitoring Faulty Components: Cisco IP SLA
• Cisco IP SLA
– Simulates predefined traffic payload across the network to
determine how the network is performing to ensure Service Levels
for IP based applications and services
– Bundled as a part of Cisco IOS
22

23. Monitoring Faulty Components in OpManager
• WAN Round Trip Time (RTT) and VoIP monitoring in OpManager
– Provides you hop-wise visibility on your WAN link
– IP SLA enabled active monitoring on every VoIP call path
– Just add the monitor in OpManager, it automatically pushes the
necessary configuration to the device and starts monitoring the
performance.

24. Monitoring Faulty Components in OpManager
In most cases a faulty component could boil down to either a overburdened
device or a fault configuration update. OpManager provides you an insight
on both these dimensions.
24

25. Monitoring Faulty Components in OpManager
OpManager supports over 150
device types of Cisco with out-of-
the-box collection of monitors.
Soon after the discovery
OpManager starts monitoring
them right away.
25

26. Monitoring Faulty Components using NCM plug-in
• OpManager NCM module, lets you
– Baseline configuration, Compare configuration side-by-side
and rollback to the trusted version in a click.
– Automate configuration updates and reduce manual and
unauthorized changes
– Ensure compliance after each configuration update
26

27. Monitoring Faulty Components in OpManager
• Is that it?
OpManager supports both Syslog and SNMP Trap processing. You have to configure
your Cisco devices to send SNMP Traps and syslogs to OpManager server. You have
options to configure custom syslog and SNMP Trap rules as well.
Syslog Processing SNMP Trap Processing
