I have 3 6500's, 2 x 6513 and 1 x 6509.

I keep hearing about a NAM module and wondering, what does a NAM module do and do I have to install 1 in each core switch?

Will it provide me more then 2 SPAN session per switch?

See for more on what the NAM is and what it does. The NAM 2 supports two space sessions where as the NAM 1 only supports one session. However, both can do RSPAN, and both offer the ability to act as NetFlow data export destinations. Using NetFlow, you can analyze traffic from a number of sources.

Many customers do install NAMs in all of their core devices. However, with RSPAN, you can create an RSPAN VLAN between the core switches, and just use one NAM 2.
