Topology Data
VPO provides a topology manager that automatically discovers and
maintains a database of TCP/IP nodes and connections. This database
includes fields that describe each node’s functionality, address, and
status. If a device has an SNMP agent, then that agent’s identification is
used to determine its capabilities and how it should be represented on
VPO maps.

The topology manager passes information to the OpenView database.
Other applications may provide discovery mechanisms for non-TCP/IP
protocols; for example, they may discover connections using MAC, WAN,
or vendor-specific protocols. As with the VPO topology manager, these
applications can store topology information in the OpenView database.
VPO can be configured to use the Oracle relational database to manage
topology information. Some customers use the query and
report-generating capabilities of this database to analyze and document
their network.
