Configuring Wired AVC Flexible Netflow
Creating a Flow Record
Wired AVC FNF supports two types of predefined flow records — Legacy Bidirectional flow records and
Directional flow records (ingress and egress). A total of four different predefined flow records, two bidirectional
flow records and two directional flow records, can be configured and associated with a flow monitor. The
legacy bidirectional records are client/server application statistics records, and the new directional records
are application-stats for input/output.
