IP ranges

You can specifically include or exclude IP addresses individually for

discovery

or as part of a range. IP

address range entries also affect

cluster

discovery. The IP ranges must include the addresses of the cluster

and its nodes. Enter one

system

or range per line. Use the following guidelines:

Range to enterIP range

172.25.76.1-172.25.76.254Your local subnet IP ranges from 1 to 254, the default Ping

inclusion ranges

Broadcast node determined by the subnet mask

Discovery assumes you do not want to ping the subnet network ID, typically the zero node, or the subnet

broadcast address, typically node 255, because these settings would unnecessarily take network resources.

If the system 255 is not a broadcast address on your network, you can indicate this in the Ping inclusion

ranges section as shown in the table above or exclude the specific system in the Exclusion ranges section.

HP Systems Insight Manager (HP SIM) uses the subnet mask to determine the broadcast system. If you do

not specify a mask, HP SIM uses the default mask for the class of network. If your subnet mask is not the

default for the class, the broadcast system can be included, generating much more network traffic than

necessary.
