Can I use the Network CI (cmdb_ci_ip_network) with Discovery?

[rwilson1]

Hi, there is a table in the CMDB called "Networks" (cmdb_ci_ip_network). I am populating this table with values from our IPAM (IP Address Management) software that we use internally to allocate IP ranges and subnets, so essentially this table will contain all information about the various networks we have.

When you create a new Discovery Schedule (Discovery --> Discovery Schedules) it looks like you have some options when choosing the "Discovery IP Range". Normally I use "IP Address List" but there is also an option to use "IP Network". Is there a way to reference this option back to the cmdb_ci_ip_network table? It looks like the Network you specify under the Discovery IP Range is completely independent from the CMDB table and would need to be maintained separately.

If I can do this, I can simply import all my subnets and VLANs from the IPAM system, and create new Discovery Schedules from there, instead of having to re-create everything manually.

Any thoughts or input appreciated.

Yes, you can do that using the Create range sets List link on IP Network table.

Check section "Convert IP networks into Discovery range sets" for more information.

You might consider an import to the range set table and associated discovery range item. That way you can apply the range set and have the import keep it updated and you never have to manage it really from the instance side.

Are you referring to the "Discovery IP Range" table? (discovery_range_item.list)
