Figure 34-28. Configuration > Discovery page Networks tab
The Include Networks section defines the outer bounds of the network to be discovered. If any
include networks are defined, only nodes that have an interface in at least one include network
are discovered.
The Exclude Networks section defines areas in the network to avoid during discovery.
Interfaces in an exclude network are added only if they are on a node that has other interfaces
that are in an include network.
The filtering provided by the include network and exclude network lists applies to ping ranges,
addresses found in ARP caches, route tables, and interface tables, and to addresses found by
broadcast pings and root cause path analysis.
Filtering does not apply to addresses specified in seed nodes. In effect, seed nodes override
filtering.
Note: If the include network list is empty, only the exclude network list limits discovery. If the
exclude network list is also empty, discovery is not limited.
Configuring Ping Ranges
The Configuration > Discovery page Ping Ranges tab is used to specify a list of IP addresses
to ping as a part of discovery. During discovery, ZoneRanger pings (sends one or more ICMP
echo requests) all addresses in any specified ping ranges that pass the include/exclude network
filtering criteria. Any address that responds is added to the database.
