Network Analysis Module

Network Analysis Module
You can also use the Cisco Network Analysis Module (NAM) to monitor ERSPAN data sources for application
performance, traffic analysis, and packet header analysis.
To use NAM for monitoring the Cisco Nexus 7000 ERSPAN data sources, see the Cisco Nexus 7000 Series
Network Analysis Module (NAM-NX1) Quick Start Guide.

High Availability

The ERSPAN feature supports stateless and stateful restarts. After a reboot or supervisor switchover, the
running configuration is applied.
For more information on high availability, see the Cisco Nexus 7000 Series NX-OS High Availability and
Redundancy Guide.

Virtualization Support

A virtual device context (VDC) is a logical representation of a set of system resources. ERSPAN applies only
to the VDC where the commands are entered.
Note You can monitor the inband interface only from the default VDC. Inband traffic from all VDCs is monitored.
For information about configuring VDCs, see the Cisco Nexus 7000 Series NX-OS Virtual Device Context
Configuration Guide.
