1 Network Performance Monitoring at Minimal Capex Some Cisco IOS technologies you can use to create a high performance network Don Thomas Jacob Technical Marketing Engineer

2 About ManageEngine Network Servers & Applications Desktop ServiceDesk Windows Infrastructure Event Log & Compliance Security Network Monitoring Server Monitoring Desktop Management Helpdesk Active Directory Windows Event Logs Vulnerability Analysis NetFlow Analysis Application Perf Monitoring Asset Management ITIL Service Desk SQL Server Syslog Management Patch Management Network Config Mgmt End User Experience Remote Control Software License Tracking Exchange Server Firewall Log Analyzer Password Management ManageEngine is an IT management vendor focused on bringing a complete IT management portfolio to all types of enterprises

3 The Webinar will discuss: Why network performance management A Network Administrator s wish list Some Cisco technologies you can use for network performance monitoring And a brief on Cisco Flexible NetFlow NetFlow Analyzer and Cisco Technologies

4 Why Network Performance Monitoring Network connectivity and business application uptime are the keywords today Increasing bandwidth but more applications and services in the network Save capex Hold the extra bandwidth or the WAN optimization device you planned Business critical applications have to compete with rogue applications in many networks Planning for VoIP Can your current links do it?

5 A Network Administrator s Wish List

6 A Network Admin s Wish List Need a Capacity Planning Report Is Peer to Peer apps using bandwidth? Traffic Analytics Manage available Bandwidth? What caused the Bandwidth Spike? Network Admin Can the existing link carry Voice Traffic? Is the Network Secure? How will the data traffic perform?

7 A Network Admin s Wish List Bandwidth Monitoring - Analyze link usage - Visualize traffic patterns - Real-time traffic reports Traffic Analytics WHO Traffic Source and related Conversations WHEN Real Time Traffic Graphs to Forever History WHAT Applications and Protocols Used WHERE Traffic Destination and related Conversations Capacity Planning - Existing link meets demand? - Increase available Bandwidth?

8 A Network Admin s Wish List Bandwidth Monitoring - Analyze link usage - Visualize traffic patterns - Real-time traffic reports Traffic Analytics Traffic Source and related Conversations Real Time Traffic Graphs to Forever History Applications and Protocols Used Traffic Destination and related Conversations Capacity Planning - Existing link meets demand? - Increase available Bandwidth?

9 A Network Admin s Wish List Layer 7 Analysis and Traffic Management Analyze Peer to Peer application usage Are unwanted applications using well known ports? Manage, Block or Shape traffic Validate Quality of Service policies

10 A Network Admin s Wish List Measure Link Capability for VoIP Traffic Switching to VoIP to carry Voice Traffic? Can existing link carry the additional traffic? Measure performance of VoIP traffic over the link Available for New Traffic Current Usage

11 A Network Admin s Wish List Link Performance Monitoring How is the WAN link performance Is your ISP delivering as per the SLA? Latency, Jitter, Packet loss, Availability???

12 A Network Admin s Wish List Growing number of Security Threats Threats Threats 70's 80's

13 A Network Admin s Wish List Growing number of Security Threats Is my Network Secure? Are the current firewall rules sufficient? Track network anomalies that may have bypasses firewalls Is your network under attack? Is there a virus spreading or maybe a DDoS attack?

14 Cisco Solutions you can leverage on

15 What Cisco has to help you Cisco s Flexible NetFlow Primary IP Traffic accounting technology Reports on Who, What, When and Where of traffic Helps understand traffic pattern, applications used, top talkers and much more???????? UDP TCP????

16 What Cisco has to help you Source Interface (ifindex) Protocol Source IP Address Destination IP Address Source Port Destination Port ToS

17 A brief about Cisco Flexible NetFlow

18 Cisco Flexible NetFlow What is Flexible NetFlow Uses NetFlow v9 - Allows user defined Key and Non- Key Fields Highly flexible flow export options - Customized traffic monitoring Ability to monitor a wide range of IP packet information which traditional NetFlow did not have

19 Cisco Flexible NetFlow Some Platforms and IOS with Flexible NetFlow Cisco ISR G1 - From 12.4(20)T IOS Cisco ISR G2 Cisco 7200 Cisco ASR1K - All CCO Images - From 12.2(33)SRE - From XE (1)S Cisco CAT 4000 series - SUP Engine 7E Cisco CAT 6000 series - SUP 2T Earl8

20 Cisco Flexible NetFlow NetFlow Performance Impact CPU Utilization 10,000 active flows 7.14 % additional CPU 65,000 active flows % additional CPU Bandwidth Usage Estimate Around 2% to 3% additional bandwidth on the NetFlow enabled device

21 What Cisco has to help you Network Based Application Recognition - NBAR Application Presentation Bitorrent, edonkey, FTP, Kazaa, Skype, SIP Session Transport Network Data Link Data Physical

22 What Cisco has to help you Network Based Application Recognition - NBAR Layer 7 traffic analytics Intelligent Application Categorization Detect Peer to Peer and dynamic port using applications Can work with CBQoS for custom traffic management

23 What Cisco has to help you Class Based Quality of Service - CBQoS Peer to Peer Web VoIP FTP Internet Link Web FTP

24 What Cisco has to help you Class Based Quality of Service - CBQoS Prioritize, limit, block or shape IP traffic Drop unwanted traffic Peer to Peer, IM, etc Ensure delivery of business critical applications

25 What Cisco has to help you Cisco IPSLA IP Service Level Agreement Monitor performance packets reach destination, link performance, availability? RTT, latency, jitter, packet loss, etc Verify if the ISP is delivering as promised Can the link can deliver your data to the destination Can the link carry VoIP traffic?

26 What Cisco has to help you Cisco NetFlow For Security Analytics Valuable information about IP traffic patterns Identify network anomalies, DDoS attacks, spread of malware or viruses Details of attack Offender, Target, Path Helps mitigate attacks that surpasses firewalls and IDS

27 NetFlow Analyzer and Cisco
