Cisco IOS NetFlow—What Is It?

• Developed and patented at Cisco Systems in 1996

• NetFlow is the de facto standard for acquiring IP operational data

• Standardized in IETF via IPFIX

• Provides network and security monitoring, network planning, traffic analysis, and IP accounting

• Packet capture is like a wire tap

• NetFlow is like a phone bill

Network World Article—NetFlow Adoption on the Rise http://www.networkworld.com/newsletters/nsm/2005/0314nsm1.html

NBAR: Full-Packet Inspection

• Used for intelligent policy (QoS, filtering, etc.) or reporting

• Identifies over 1200 applications and protocols TCP and UDP port numbers – Statically assigned

– Dynamically assigned during connection establishment

– RTP and RTP payload type identification

– Cisco TelePresence media and signaling supported in IOS 15.1(3)T

– WebEx desktop-share/audio/video supported in 15.2(2)T

• Non-TCP and non-UDP IP protocols

• Data packet inspection for matching values

MSP and MSI What’s the Difference?

Capabilities MSI MSP Considerations

Auto discovery of the endpoint and auto configuration of

the switch port

Limited to protocols (SIP, H323, mDNS, CDP, LLDP, SIP, DHCP) supported

by MSP – surveillance cameras & collaboration endpoints

Location awareness on endpoints/ applications (learned

from the network)

Auto discovery of services by application

Performance Monitoring on endpoint Network can independently monitor traffic

Dynamic troubleshooting on endpoint – Mediatrace

Identify the flow and apply the appropriate policies (e.g.

QoS, monitoring, routing, etc.) MSP recognizes the type of flow by gleaning a limited set of signaling

protocols (RTSP, SDP, SIP, H.225, H.245) and they have to be visible to

MSP

Application specific information sharing with the network

MSI can share any attributes with the network whereas MSP is limited to what

is available from the signaling protocols

Works with application traffic encryption

Resource reservation MSP can reserve bandwidth on behalf of the endpoint

3rd Party support MSI licensing will be available in Q3CY2012
