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.

Network Mapping in OpManager

9

• Automatic Layer2/ Layer 3 Network mapping• Custom device grouping• Traffic weather map


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

• 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

• 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.

Bandwidth / Traffic

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

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

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…

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.

Use case


Problem:

Root cause Solution


• 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


• 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

Monitoring Faulty Components

21

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

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.

23


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


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

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

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
