Monitoring Traffic with a VRF Instance and a Monitoring Group

The first way you can implement passive flow monitoring is to direct traffic into a VRF routing instance and use a monitoring group to export this traffic to a flow server for analysis. Complete the following tasks:

Specifying a Firewall Filter to Select Traffic to Monitor
Configuring Input Interfaces, Monitoring Services Interfaces, and Export Interfaces
Establishing a VRF Instance for the Monitored Traffic
Configuring a Monitoring Group to Send Traffic to the Flow Server
Configuring Policy Options
Option: Stripping MPLS Labels on ATM, Ethernet-Based, and SONET/SDH Interfaces
