Excluding Network Devices from discovering

Hi All,


We have 4000 devices Inventory license on DDMi 9.32, stil not yet started with DDMi implementation.


Customer has 9 locations with differnt subnets, where devices like Desktops, Laptops, Servers, Workstaion & Network Printers need to be discovered & Inventoried.


In 9 locations IP subnets we have all types of  devices, our requirement is need to exlcude all network devices been discovered & inventoried in those subnets only windows devices needs to be discovered & Inventoried.


Can someone please help me in providing me the best practice how this can be performed.

Re: Excluding Network Devices from discovering

Basic discovery in DDMI is to ping the IP addresses in discovery ranges; any Ip addr respond to ping request will be discovered.


Therefore, the only way to prevent discovering NCDs is not to let DDMI ping those devices. You can either block NCD IP addresses in DDMI configuration or block ICMP ping in those NCDs.


In addition to that DDMI uses "arp entries" (from snmp-managed NCDs and DHCPs), call-home, and virtual discovery methods to discover the devices. Call-home and virtual discovery don't apply to NCDs. If you are not planning to model your devices through snmp agent, you don't need to worry about arp entries either.

Also, dont get your "Devices Inventoried = 4000" license confused with "Devices Discovered = #####" license.


HP mainly charges you for "Devices Inventoried"... and not so much concerned with "Devices discovered".  If you have 4k devices inventoried, you should have at least like 10-15k "Devices Discovered", which should cover you for all your IP addresses...

Re: Excluding Network Devices from discovering

Also if you have specific set of IP ranges for the network devices (as most corporate follows), please create some device group with high ranking and exclude them from all configuration profiles (so that those machines are not touched - inventoried)
