Several common TCP services and their associated ports are configured for discovery.

A list of common
routers and switches.
During initial configuration, you are given the option to automatically run discovery after initial
configuration is complete. If this option is accepted, discovery runs, using these default settings,
immediately after the ZoneRanger completes its initial startup. In addition, the periodic discovery
option will be enabled with a default interval of 7 days. If this option is declined, you can wait until
the ZoneRanger starts up, modify the discovery settings as desired, and then either invoke discovery
manually or configure periodic discovery.
Incremental Discovery
As an alternative to running the full discovery algorithm, ZoneRanger also provides a mechanism
whereby the user can request that a short list of IP addresses or hostnames be scanned and
incrementally added to the database. When this mechanism is invoked, the ZoneRanger will scan
each provided IP address or hostname using SNMP and TCP and will update the ZoneRanger
database with the resulting information. If a new IP address or hostname is scanned, information for
that device will be added to the database. If an existing IP address or hostname is scanned, the
information in the ZoneRanger database for that device will be updated.
Note that incremental discovery is intended as a shortcut, to be used in cases where executing the
full discovery algorithm would consume too much time. Accordingly, the incremental discovery
algorithm does not gather subnet or path information for added devices. As a result, root cause
information will not be available for these newly added devices until a full discovery is executed.
