DEPLOYMENT CONSIDERATIONS AND PLANNING
Cisco PVM works in conjunction with the Cisco Network Analysis Modules (NAMs) to provide you in-depth visibility into your network
traffic. In Cisco PVM 1.0, traffic statistics are collected from the NAMs and their associated Switches/Routers. Technologies such as RSPAN
and Netflow can be used to gather data from other devices.
Cisco PVM communicates with the NAMs and their associated devices through SNMP. The data that is gathered from the NAM modules
comes from the SNMP MIBs (Management Information Bases) that the NAM supports (RMON, DSMON and ART). Cisco PVM collects
SMON (VLAN statistics) and mini-RMON (port statistics) and MIB II (interface statistics) information directly from switches and routers.
Once NAMs have been deployed and configured, Cisco PVM can be installed and deployed on any machine that meets the hardware and
software requirements and has network access to the deployed NAMs and their devices. Figure 1 shows a sample deployment scenario.

Steps in the PVM Deployment Process
The steps in the PVM deployment process are as follows. High level descriptions of each of these steps are provided in the sections that follow.
1. Get answers to the basic questions about the network problems to be addressed (as listed in the following section).
2. Determine the optimal locations where you can place Cisco NAMs in your network.
3. Set up the Cisco NAMs and configure them to collect the desired statistics to solve the problem.
4. Deploy Cisco PVM and add the NAMs and their associated devices in PVM.
