Discover Subnet
To open the Discover Subnet dialog, either click the Discover Subnet icon on the NavBar, or on the OidView Toolbar (see OidView Console ).
The Discover Subnet tool
allows a user to enter a variety of different criteria to either find as many agents as possible, or even narrow
down results for only those systems and/or agents that correspond to the exact configuration desired. It uses
a combination of ICMP (ping) and SNMP. If something is found to respond, the grid will list a green light.
If it does not respond, a red light will be displayed.
There are two stages to discovery, Stage 1 (ICMP), and Stage 2 (SNMP). If ICMP is unchecked, there will
only be one stage for discovery (Stage 2), but it will be much slower because it does not have the advantage
of knowing which agents to target (as Stage 1 with ICMP helps to determine that). We recommend leaving both ICMP and SNMP checked, if possible.
Get Device Capabilities
tells Discover to look for basic device capabilities during stage 2. For example, is this a router or a switch? Is
it a printer, a probe, a battery? There is a file located in the profiles subdirectory called mDiscoverRules.xml,
which can be edited to modify how OidView classifies these agents. If you decide to change this file, it is
best to contact ByteSphere support with your changes so we can include them in the latest distribution.
The following criteria can be used to find agents on a network:
1. ICMP and/or ICMP
2. IP Address Ranges (as many as needed)
3. Community Strings (as many as needed)
4. UDP ports (as many as needed - you are not limited to only 161)
5. OID Filters (list agents only responding to a specific OID)
