NM-NAM Data Sources - Interfaces
The NM-NAM allows for the direct monitoring and analysis of WAN interfaces by using CEF to copy the
packets to the internal NAM interface for processing. When multiple interfaces are copied to the NAM, the
NAM aggregates the data. CEF can be used to forward both WAN and LAN data streams.
The NM-NAM also has an external interface that can be used for monitoring and analysis of connected LAN
links. This connection could be to a hub to view a LAN segment or to a Switch SPAN port for more flexible
port and VLAN analysis.
