IP Network probe

For an IPv4 system, the IP Network probe examines the system’s IP address table (ipAddrTable) to combine the IP addresses and the netmask for each interface on the system to create IPNetwork objects, and to build the connected relationships between IP endpoints and IP networks.

For an IPv6 system, the IP Network probe examines the system’s IP address table to create IPv6Network objects, and to build the connected relationships between IPv6 endpoints and IPv6 networks.

For a dual-stack system, the IP Network probe examines the system’s IP address table to create IPNetwork and IPv6Network objects, to build the connected relationships between IP endpoints and IP networks, and to build the connected relationships between IPv6 endpoints and IPv6 networks.

The IP Network probe uses standard MIB-II information to discover IP addresses.

The IP Manager attempts to discover and monitor IPv6 addresses on devices that implement and populate either of the following MIBs:

• IPV6-MIB (.1.3.6.1.2.1.55)

  or

• CISCO-IETF-IP-MIB (.1.3.6.1.4.1.9.10.86)

  For devices that are implementing other MIBs, the IP Manager discovers and monitors only IPv4 addresses.
