Figure 2. Places in the Network in Which NAMs Can Be Deployed
Choice of Hardware and Software Platforms for a Given Place in the Network
There are multiple platforms on which NAM software is supported. Depending on the usage scenario and the
location in which the NAM will be deployed, you must make a decision on the type of NAM hardware to deploy. This
section provides the necessary background and details to make such deployment decisions. See Table 1.

Catalyst 6500/
Cisco 7600 blade
The NAM blade fits into any slot on a Catalyst 6500 or
Cisco 7600.
Cisco 7600.
The NAM-2 blade has two data ports. These ports
connect directly to the switching fabric and are not
externally visible. Each port can support one SPAN
session. Therefore, the NAM-2 blades support a total of
two SPAN sessions, while the NAM-1 blades support
one SPAN session.

Notes:
The older versions (without the -250S suffix) also support
NAM 4.2. Their performance is not on par with the latest
version of hardware. If required, currently owned NAM-1 and
NAM-2 cards can be upgraded easily using a memory
upgrade kit. The kit essentially provides an upgrade to the
RAM on your NAM cards and offers an easy way to meet the
performance needs of NAM software while allowing continued
use of the existing NAM hardware investment.

Notes:
Because the network modules have an internal and an

from a router interface or directly tap into traffic from an
external device using the external Ethernet port.
