You can create user-defined locations and assign these locations to networked devices by specifying IP address ranges that are applicable to the location. After assigning an IP address range to a location, you can autofill this location to associated devices and computers. The Service Manager server uses these ranges to identify which configuration items should be automatically mapped to the given location. You can provide multiple ranges for a location.
If you provide multiple ranges, the asset processor tries to find the smallest IP range that matches. If there is more than one match, then it takes the one with the lowest start address. If there is still more than one match, for example, if two locations have the same range specified, then the location is picked randomly.
You can also specify a range to exclude within a given IP range.
You also have the ability to override default locations for specific devices and disable automatic location updates for them.
The process for automatically updating the location of a configuration item is as follows:
•Create locations and assign IP addresses to them. See Creating Locations and Assigning IP Address Ranges.
•During an audit, the network or IP addresses are populated, which allows the devices to be automatically linked to locations. Or you can run a quick action to apply new IP ranges to the configuration items in the location, as described in Applying IP Ranges to Configuration Items.
•If appropriate, override the defined subnet location for a configuration item and choose another location to assign to it, as described in Overriding a Specified IP Range Location.
1.Log in to Service Manager as a Configuration Manager or Discovery Manager.
2.Open the CI Location workspace. The existing location records is displayed in a list view.
3.Click New CI Location.
4.In the Location field, enter a location name.
5.Click IP Range Mapping.
6.Click New Device Subnet.
7.In the window that opens, do the following:
•Specify the IP address range in the Address Range Start and Address Range End fields.
•To exclude a range within the range you specified, click New Device Subnet again.
•In the Address Range Start and Address Range End fields, specify the range that should be excluded from within the IP range you specified earlier.
•Check Exclude to exclude the range.
For example, if you specify a range from 192.172.0 to 192.172.255, but you want to exclude a range within the specified range, you can create another location mapping from 192.172.200 to 192.172.250 and check Exclude.
1.Create locations and map IP ranges to them, as described in Creating Locations and Assigning IP Address Ranges.
2.From the Action Menu, select Location Mapping and then select Apply Now.
3.If you open a configuration item record to which this subnet is associated, the application populates the CI Location field with the location that you assigned. Check Override IP Range Location to override the assigned location, then select another configuration item location, as described in Working with Audits.
1.Log in to Service Manager as a Discovery Manager.
2.Open the CI workspace.
3.Search for the configuration item with the configuration item location to override.
4.Select the record and open it.
5.Check Override IP Range Location.
