There is an SNMP ipAddress on every node, whether it has one interface or many. Cordially, Leslie A. Clark IT Services Specialist, Network Mgmt Information Technology Services Americas IBM Global Services (248) 552-4968 Voicemail, Fax, Pager
Hello again, I notice I made a couple of mistakes in this (I guess that's what happens when you try doing too many things at once ;-). With the subnet calculation thing, it may be calculating based on IP Address/Subnet Mask, or, it may be basing the information on nodes that are appear in specific subnets in NetView (which would have to be based on the TopM Network/Segment ID fields associated with the interface objects in the OV Object Database). In my contiguous subnet example, I should have used an OR (||) instead of AND (&&): # nvUtil e '((IN_SUBNET 192.168.254.0) || (IN_SUBNET 192.168.254.1))' Apologies for the errors.

Hello, One thing you need to keep in mind with when using the "SNMP ipAddress" field is that it will only work for single interface devices. If you are trying to get a list of multiple interface devices you will need to approach this differently. One method using nvUtil is (which can be used for creating a smartset): # nvUtil e '(IN_SUBNET 19.39.0.0)' The only problem with this is that it is based on a calculation of IP Address and Subnet Mask to determine which hosts match. If there are incorrect Subnet Masks results could be incorrect. This calculation thing also means that you would need to have more than one entry if you were looking addresses in a contiguous set of subnets... eg. ((IN_SUBNET 192.168.254.0) && (IN_SUBNET 192.168.254.1)) If you are just wanting to get this list from the command line or a script, a .format file with the nvdbformat command could be used: ########################################################### # # NVDBFormat interface listing .format file # Modified version of interfaces.format # # Usage: nvdbformat -f <filename> # # If this file were named 'interfaces.format' it would be processed by: # # nvdbformat -f interfaces.format # ########################################################### SELECTRULE:isInterface=TRUE SELECTRULE:IP Address~19.39.*.* SELECTFIELD:1:TopM Node ID:Selection Name SELECTFIELD:2:IP Address SELECTFIELD:3:IP Subnet Mask SELECTFIELD:4:IP Status # GROUPBY:1:TopM Node ID:Selection Name SORTBY:1:IP Address # HEADER:Interface List by Selection Name HEADER:Selection Name,IP Address,IP Subnet Mask,IP Status # OUTPUT:${1},${2},${3},${4} # With some modification and cron, this could be used to create/maintain a smartset with a list of nodes that meet fit. # run nvdbformat command to get Selection Name list # run nvUtil command to create a smartset with the selection names: nvUtil a "Smartset Name" "description" "(IN '"host1" "host2"')" Hope this helps.

Look at the object info for a node. Nodes don't have a field 'IP Address'. That's an attribute of an interface. So you are getting a list of Selection Names of interfaces or Networks. Nodes do have a field called 'SNMP ipAddress'. Cordially, Leslie A.

I tried making a smartset based on ip's: nvUtil e '("IP Address" ~ "19.39.*.*")' But the results that I get are not
nodes but something else: How do I make a smartset, based on a range of ip's, AND get actual nodes in it? Thanks in advance
