A Note on the Cisco 2200 Series Appliances
The NAM software is available as an appliance in addition to the existing platforms. The addition of the appliance to
the NAM product line provides increased flexibility and higher performance. As mentioned in Table 1, the appliance
is available in two varieties. The Cisco NAM 2220 appliance offers the best performance in the NAM product line.
The product contains two 10 Gigabit Ethernet ports that are ideally suited to high bandwidth data center and core
environments. The Cisco NAM 2204 appliance contains four 1 Gigabit Ethernet ports, available both in copper and
fiber, and allows flexible deployment in a variety of locations across the network.
The appliance version serves as a complement to the network module versions. The network modules (or cards)
reside within an ISR, Catalyst 6500 Switch, or Cisco 7600 Router and offer an integrated solution. Such integration
saves rack space and power, eliminates the need for additional cabling, and efficiently monitors device traffic with no
network overhead. Still, there are situations where an appliance is preferred. For example, you may wish to monitor
a Catalyst 4500 Switch or a Nexus 7000 Switch that does not support NAM network modules. Or you may wish to
connect the NAM to multiple switches in parallel as you build a new segment in the network. This can be achieved
easily with the Cisco 2204 appliance, which has four ports that can each be connected to different devices. Or you
may want to monitor traffic from a couple of core routers that feed into the data center and therefore require 10
Gigabit Ethernet ports. The Cisco 2220 appliance might be ideally suited for this scenario. The addition of the
appliances to the NAM product line provides users with additional flexibility in deploying the appropriate NAM
hardware depending on the location in the network.
Enhanced performance also provides other deployment benefits. For example, the number of voice streams
supported by NAM is an important consideration while planning for voice over IP quality monitoring. Other limits
include number of NetFlow records processed per second, buffer sizes available for packet capture, number of WAE
devices that send WAN optimization data to NAM, and in general, monitoring performance under load.
The appliances are not integrated into Cisco infrastructure, but they do support some of the features that the
integrated NAM modules bring. On the integrated Catalyst 6500 NAM cards, you may have used the ability to poll
MIBs on the supervisor and collect statistics on important aspects such as switch CPU health, interface traffic,
utilization, and so on. The appliance defines the concept of a “managed device” that achieves the same result for the
device being monitored. You will need to choose one of the Cisco devices (supported platforms include Catalyst
6500, Cisco 7600, and Catalyst 4500 Series devices) being monitored by the appliance as your managed device.
The NAM appliance will be able to poll MIBs on this managed device and obtain relevant performance
troubleshooting information just like the NAM cards. Also available is the ability to configure SPAN sessions on the
