네트워크 성능 관리 (8분)

어느 사용자/어플이케이션이 가장 많은 트래픽을 일으키는지 알 수 있습니다.

기존의 SNMP 감시 방식으로는 지난 밤 어느 사용자가 토렌트로 영화를 다운받았는지, 어느 서버가 좀비 PC가 되어 불법 트래픽을 내뿜는지 알 수 없습니다.

네트워크 트래픽 분석 및 트러블슈팅

OpManager의 NetFlow 플러그 인은 flow 기반 네트워크 트래픽 분석을 가능하게 해 줍니다. 이 플러그 인의 기능은, 현재 누가 어느 인터페이스를 사용하여 어느만큼의 대역폭/트래픽을 사용하며, 그 대역폭/트래픽을 사용하는 사용자/어플리케이션/source/destination 등에 대한 정보를 제공해 줍니다. NetFlow 플러그 인을 사용하여 다음과 같은 작업이 가능합니다.

  • 네트워크 트래픽에 대한 자세한 정보 획득
  • Cisco NBAR을 사용하여 Skype등의 특정 대역폭 사용 어플리케이션 탐지
  • LAN과 WAN의 급작스런 대역폭 사용량 상승, DoS / DDos 공격, 네트워크 성능 저하
  • Cisco CBQoS를 사용한 네트워크 QoS 정책 효과 검증
  • 수집된 월별 트래픽 추세를 사용한 차후 용량 계획
  • ISP에서 청구된 네트워크 사용비와 대조

"The new Netflow plug-in proved invaluable in troubleshooting a recent VPN outage. I highly recommend both OpManager and the Netflow plug-in"

NetFlow Plug-in FAQs

he NetFlow plug-in is available as a separate downloadable file to be installed over OpManager, enabling both collection and analysis of various flows such as netFlow, JFlow, SFlow e.t.c..

Gain in?depth information on network traffic composition

Know what your network traffic is comprised of through reports on top applications, hosts, protocols, DSCP etc. for every link and for any configurable IP based group. You can analyze your network traffic over multi?vendor routers and switches through the NetFlow Plug?in. Supported network protocols include NetFlow® version 5, 7 and 9, sFlow®, cflowd®, jFlow®, IPFIX®, NetStream® and Cisco® NBAR technology.

Use advanced application recognition

The NetFlow Plug?in’s ability to map applications by combining IP Address, Port and Protocol enables you to know in detail about your applications using the network bandwidth. Further, you can also identify applications (e.g. Skype) that use dynamic ports using Cisco’s Network Based Application Recognition (NBAR) and ensure that these do not consume huge bandwidth.

Did you Know?

You can also disable switch ports through OpManager. So once you identify the host causing the traffic jamming, you can get into the switch monitoring dashboard in OpManager and from there disable the port connected to the troubling host.

Troubleshoot bandwidth problems

The NetFlow plug?in supports custom application mapping which helps you extract accurate network traffic utilization reports. You can know exactly what applications have been using bandwidth and for how long, you can also further drill?down to see the top hosts using those applications. In case of worms, virus or Denial?of?Service (DoS) attacks, the NetFlow plug?in facilitates quick problem isolation and resolution to bring down your Mean Time To Resolve.

Validate network QoS policies

The Cisco CBQoS add?on helps you qualify the QoS policies set on the router and ensure that the right type of traffic gets priority in the network. By studying the traffic composition at pre?policy and post?policy together with the resultant dropped traffic, you can easily judge effectiveness of the implemented QoS policy.

Make important capacity planning decisions

The NetFlow plug-in allows you to create powerful custom reports to analyze bandwidth usage trends in detail e.g. bandwidth used by a specific host/ network accessing an application during a particular week. By creating IP address based departments / divisions and filtering based on applications and interfaces, you also get critical inputs for enterprise bandwidth capacity planning.

Have your own bandwidth billing system

You can now rest your suspicions of being overcharged by cross?checking ISP charges with your own billing system available with the Billing add?on. You can also associate bandwidth costs to each department in your organization to help you plan well with allocated bandwidth budgets. The Billing add?on over the NetFlow plug?in helps you to account your bandwidth by assigning costs to usage (volume?based) or bandwidth (speed?based).
