Configuring Layer 3 Topology Discovery
For the MARS to reach full operability, you must specify its community strings and select the networks
that you want to discover. Once the appliance discovers these networks, you get a more accurate view of
MAC addresses, end-point lookup (attack paths), and network topology. Topology discovery enables
operation level three, see
Levels of Operation, page 2-1

See
Figure 17-13 on page 17-7
