Network Type and Addresses— Select the type of entry in the pick list (IP Address(es),
CIDR Address, Hostname, SNMP Broadcast, Subnet).
The tooltips in the data entry field tell what valid entries look like.
NOTE:
When specifying network addresses using the Subnet type, you must specify the Network address at the
beginning of the subnet since Dell OpenManage Network Manager assumes it is the starting IP address
for the range. If you specify an address in the middle of the subnetwork then Dell OpenManage Network
Manager may discover devices outside of that subnetwork. This also means that IP addresses in the
network that precede the specified address are not discovered. To avoid these issues, use the CIDR
specification of the network to discover rather that the subnet ID.
Authentication—You can create new, or add existing authentications. See Authentication on
4
page 143 for the way to create such authentications outside the discovery process.
Notice that authentications appear with Edit / Delete icons and Up / Down arrows on their
right. The Edit icon opens the authentication editor. Click the arrows to arrange the order in
