Chapter 1 Configuring the Network Analysis Module
Configuring the NAM
Note Classification of received data from data sources to sites is done only after the sites are configured. Any
old data from these data sources before the sites were configured are counted under the default
'Unassigned’ site.
The site definition is very flexible and can accommodate various scenarios. The site definition is used
not only for viewing of data but for data export and data retention as well. Typically, a site is defined by
its subnet(s), but a site can also be defined using the following rules:
• Subnet (IP address prefix)
• Subnet from a data source
• Subnet from a given VLAN of a SPAN data source
• WAE device serving the site
We recommend that you define sites using subnets whenever possible.
Note The same rule cannot be defined in multiple sites.
Note If you are configuring a WAAS device, you must add WAAS servers to the NAM. See Auto Creating a
New WAAS Device.
To display accurate data on charts and dashboards, you must configure every site on which WAAS is
planned to be deployed on the NAM. To get a breakdown of the traffic volume and response time for
each branch and the data center, configure the IP subnets for all the sites that has WAAS deployed.

Definition Rules
Typically, subnets alone are sufficient to define a site. For example:
Site Data-Center = subnet 172.20.0.0/16
In certain scenarios when there are overlapping IP address spaces in the networks (for example, in
private networks where hosts from different sites have the same IP addresses), you can use data sources
or VLANs to differentiate the subnets. For example:
Site NewYork = subnet 10.11.0.0/16 from "NDE-NewYork" data source.
Site LosAngeles = subnet 10.11.0.0/16 from "NDE-LosAngeles" data source.
Site Sale-Dept = subnet 10.11.0.0/16 from VLAN 10 of "DATA PORT 1" data source.
Site Finance-Dept = subnet 10.11.0.0/16 from VLAN 12 of "DATA PORT 1" data source.
