Manage IP Domains

HID_View_a_List_of_IP_Domains
To monitor multiple tenants or environments with overlapping IP addresses, create an IP domain. Data sources report a domain identifier. This identifier associates monitored items with specific IP domains and tenants. Items that are not assigned to a custom IP domain in the data source are associated with the Default Domain.
The Default Domain is created automatically. This domain includes the items that are not assigned to a custom domain in the data source.

You can view a list of IP domains from the
Manage IP Domains
page. To view this page, hover over
Administration
,
Configuration Settings
, and then click
IP Domains
.

Add or Edit an IP Domain

  • Updates to device alias names and interface descriptions can take up to 5 minutes to appear.
  • Editing an IP domain does not change the historical data for monitored items.
The procedure requires the Administer IP Domains role right.
Follow these steps:
  1. From the
    Manage IP Domains
    page, click
    New
    or select the IP domain that you want to edit, and then click
    Edit
    .
    The
    IP Domains Administration
    dialog opens.
  2. Specify a domain name and description.
  3. (Optional) Configure a device alias name or interface description override. Click
    Browse
    , select the file, and then click
    Open
    .
    The CSV or TXT file must includes the following format:
    IP_Address,name,description,alias/alternate_description
    Use the primary IP address of the associated devices. To find the primary IP address, look at the Address column of the Inventory Devices list.
    You can use the same alternate interface descriptions for more than one interface.
    Example:
    172.24.36.107,ethernet_7,vmxnet3 Ethernet Adapter,Connection to Dallas
    To change or remove an alternate description or device name alias, import a new file. To remove the alias or alternate description, leave the final column blank. When you remove the alias or alternate description, the original name or description reappears. If you change or remove alternate descriptions or device name aliases from a file using a spreadsheet program, include a column heading for that column.
    The preferred method to update device alias names and alternate interface descriptions is through REST.
    For more information, see Set Device Alias Names Using the Devices Web Service.
    To update multiple device alias names, use the
    update_alias_name.sh
    script that is included with
    DX NetOps Performance Management
    .
    For more information about this script, see Set Alias Names Using a Script.
  4. (Optional) To assign a primary and secondary DNS address for the domain in
    DX NetOps Network Flow Analysis
    (NFA), select
    DNS Settings
    , and then specify the required values.
    Only NFA uses the DNS settings.
    DX NetOps Performance Management
    does not directly use the DNS settings.
  5. Click
    Save
    .
The IP domain displays in the list. The changes apply to the data sources in the next synchronization.

Assign Items to an IP Domain

You can assign the following managed item types with an IP domain:
  • Devices
  • Interfaces and interface addresses
  • Networks
  • VoIP Locations
Data collectors associate managed items with a single IP domain. To enable multi-tenant deployments, assign an IP domain to each data collector.
You cannot move items from one IP domain to another.
To assign items from other data sources to an IP domain, see the documentation for that data source or see the following pages:
DX NetOps Spectrum
(Spectrum) determines which models are synchronized with
NetOps Portal
using IP domains.
For more information, see the
DX NetOps Spectrum
documentation
.
Use the following process to assign managed items to an IP domain:

Delete an IP Domain

Deleting an IP domain does the following:
  • Deletes the monitored items in that IP domain, including historical data. This also deletes the items from registered data sources that use IP domains, such as NFA,
    DX NetOps Mediation Manager
    (DX NetOps MM), and (23.3.10 and lower)
    CA Application Delivery Analysis
    (CA ADA). Spectrum devices in the IP domain are removed from
    NetOps Portal
    , but Spectrum continues to monitor the devices.
  • Deactivates the data collectors and discovery profiles that are associated to the IP domain.
    You can continue polling or discovery by assigning these data collectors and discovery profiles to another IP domain.
    To retain associated data, do not delete an IP domain. You cannot recover deleted data.
Follow these steps:
  1. From the
    Manage IP Domains
    page, select the IP domain that you want to delete, and then click
    Delete
    .
  2. At the prompt, confirm the deletion by clicking
    Yes
    .
The IP domain is deleted.
