Network Analysis Module

For more information on Control Plane Policing, See the Cisco Nexus 7000 Series NX-OS Security Configuration
Guide.
Network Analysis Module
You can also use the Cisco Network Analysis Module (NAM) to monitor NetFlow data sources. NAM enables
traffic analysis views and reports such as hosts, applications, conversations, VLAN, and QoS. See the NAM
configuration example in the Configuration Examples for NetFlow.
To use NAM for monitoring the Cisco Nexus 7000 NetFlow data sources, see the Cisco Nexus 7000 Series
Network Analysis Module (NAM-NX1) Quick Start Guide.
High Availability
Cisco NX-OS supports stateful restarts for NetFlow. After a reboot or supervisor switchover, Cisco NX-OS
applies the running configuration.
Because the flow cache is not preserved across restarts of the process and packets that come to the software
during restarts cannot be processed, all of the flows during switchovers are lost and cannot be recovered.
Virtualization Support
A virtual device context (VDC) is a logical representation of a set of system resources. Within each VDC,
you can configure NetFlow. By default, Cisco NX-OS places you in the default VDC and any flows that you
define in this mode are only available for interfaces in the default VDC.
For information about configuring VDCs, see the Cisco Nexus 7000 Series NX-OS Virtual Device Context
Configuration Guide.
