Monitor 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 cflowd server for analysis. Complete the following tasks:
- Specify a Firewall Filter to Select Traffic to Monitor
- Configure Input Interfaces, Monitoring Services Interfaces, and Export Interfaces
- Establish a VRF Instance for the Monitored Traffic
- Configure a Monitoring Group to Send Traffic to the cflowd Server
- Configure Policy Options
- Option: Strip MPLS Labels On ATM and SONET/SDH Interfaces
