White Paper
Cisco Catalyst 3K-X Service Module: Enabling
Flexible NetFlow in the Access
Introduction
User mobility, virtualization, and a rapidly increasing number of applications make enterprise networks today more
complex and difficult to manage. Cisco
®
Flexible NetFlow provides complete visibility in the network, allowing
administrators to promptly react to security attacks and to effectively perform performance monitoring and network
troubleshooting tasks.
This white paper illustrates how Flexible NetFlow analysis can be extended to the access layer with the new uplink
service module available for Cisco Catalyst
®
3560-X and 3750-X Series Switches.
Technology Overview
The new 10GE service module introduces line-rate Cisco TrustSec
®
MACsec and Flexible NetFlow in the Cisco
Catalyst 3560-X and 3750-X Series Switches.
Cisco Trustsec MACsec implements hop-by-hop data link encryption, making sure of complete data confidentiality
between two switches. How MACsec operates in the Cisco Catalyst 3560-X and 3750-X is illustrated in a separate
white paper.
Cisco Flexible NetFlow is a standard method, defined in RFC 3954, for computing user-configurable statistics on
traffic flowing through a particular network boundary. The new service module is capable of real-time Flexible
NetFlow analysis on traffic traversing its physical and logical interfaces.
Cisco Catalyst 3750-X Series Switches can stack with previous 3750-E, 3750-G, and 3750-V2 Series. Deploying
the service module in the stack enables Cisco Flexible NetFlow functionality across all switches in the stack, thus
realizing a true investment protection.
