9. If you want to discover devices located on your network within a specific
range of IP addresses, complete the following procedure.
Note: Only one selection method may be used per defined discovery.
a. Click IP Ranges in the Selection Method menu, and then, for each IP
range, provide both a Start address and an End address. Scheduled
discovery profiles should not use IP address ranges that include nodes
with dynamically assigned IP addresses (DHCP).
b. If you want to add another range, click Add More, and then repeat
the previous step. If you have multiple ranges, click X to delete an
incorrect range.
c. If you have added all the IP ranges you want to poll, click Next.
10. If you want to discover devices connected to a specific router or on a
specific subnet of your network, complete the following procedure:
Note: Only one selection method may be used per defined discovery.
a. Click Subnets in the Selection Method menu.
b. If you want to discover on a specific subnet, click Add a New Subnet,
provide both a Subnet Address and a Subnet Mask for the desired
subnet, and then click Add. Repeat this step for each additional subnet
you want to poll.
c. If you want to discover devices using a seed router, click Add a Seed
Router, provide the IP address of the Router, and then click Add.
Notes:
n Repeat this step for each additional seed router you want to use.
n Network Sonar reads the routing table of the designated router
and offers to discover nodes on the Class A network (255.0.0.0
mask) containing the seed router and, if you are discovering
devices for an SolarWinds NPM installation, the Class C networks
(255.255.255.0 mask) containing all interfaces on the seed router,
using the SNMP version chosen previously on the SNMP
Credentials page.
n Networks connected through the seed router are NOT
automatically selected for discovery.
Confirm that all networks on which you want to conduct your network
discovery are checked, and then click Next.
