Troubleshooting and Advanced Configuration

5-1

During the ProSafe NMS Server installation you entered the address, netmask, and community 
name for one SNMP V1 discovery seed device. This is normally enough information to discover 
most of your network. When you first start ProSafe NMS it will take several minutes for discovery 
to start adding objects to the map. Use the Root Subnet button to display the top-level Map view. 

If you used the Disable Discovery on Startup option of the installation, discovery will not be 
running when you first start ProSafe NMS. In this case, you need to set discovery filters before 
proceeding. Please refer to 

 before reading this 

section.

Discovery creates a two-level IP Subnet based topology. At the top-level, discovery adds any 
multi-port devices (routers) and subnet icons for each IP Subnet. Link objects are added between 
each router and the subnets it is connected to. The map is automatically arranged in a star 
configuration.

All single-port SNMP devices and ICMP (Ping) devices are added to the second level under each 
subnet icon, based on the device IP address and subnet mask. A single Bus Network is added to 
each subnet level, and all devices in the subnet are linked to this network. 

Use the Root Subnet button to display the top-level Map view. You should see a mixture of SNMP 
device icons and subnet icons, connected by links in a star configuration. Double-click on one of 
the subnet icons. You should see a Bus Network with devices linked to it in a grid configuration.
