Use the SNMP tab of the Configuration Manager 2007 Network Discovery Properties dialog box to designate the specific SNMP communities for Configuration Manager to search during discovery, as well as the maximum number of router hops that Network Discovery will make.
If possible, you should specify all the community names used in your network so that Network Discovery can more effectively search as many routers as possible. When Network Discovery encounters a new router, it uses the router's hardware cache (its net-to-media tables) to find additional subnets and other SNMP devices.
The SNMP tab contains the following elements:
- SNMP community names
- Specifies the names of SNMP community names that are processed
by the Network Discovery method. Only the community name is
displayed.In processing these SNMP communities, Network Discovery
tries names starting at the top of the displayed list and works
down the list. Each community is retried once if it fails.
Successful names are then remembered, and Network Discovery will
try them first the next time it communicates with the routers that
use that community name.
The following options are available for managing the SNMP community associated with this method:
NoteCommunity names are case-sensitive. - New icon: Opens the New SNMP Community
Name dialog box to add a community name to the discovery
polling list.
- Delete icon: Deletes the selected community
name from the discovery polling list.
- Move Up icon: Moves the selected community
name up one position on the displayed discovery polling list.
- Move Down icon: Moves the selected community
name down one position on the displayed discovery polling list.
- New icon: Opens the New SNMP Community
Name dialog box to add a community name to the discovery
polling list.
- Maximum hops
- Specifies how many router hops to make beyond the server from which Network Discovery is launched. You can specify as many as 10 router hops using the drop-down list. The default value of 0 causes only the local subnet to be searched to discover resources.For more information on router hops and their impact on Network Discovery, see About Router Hops in Network Discovery.
