Add Custom IP Domains

Administrators can set the domain assignment for Harvesters, routers, interfaces, and custom virtual interfaces (CVIs). We recommend that you set up any custom tenants and domains you need before you add the Harvesters.

Administrators can set the domain assignment for Harvesters, routers, interfaces, and custom virtual interfaces (CVIs). We recommend that you set up any custom tenants and domains you need before you add the Harvesters.
Having the appropriate IP domains set up helps to achieve the following goals:
  • Assign the correct tenant-domain when you add Harvesters so that their routers and interfaces inherit the correct associations. The routers have the appropriate SNMP profiles available to poll their interfaces.
  • Make specific content accessible only to the operators who need to monitor it.
  • Enable Administrators to create domain-specific ToS labels, protocol groups, and Autonomous System (AS) names in
    DX NetOps Network Flow Analysis
    .
  • Avoid IP address conflicts.
    For example, suppose a router with a single IP address has interfaces that belong to different enterprises. The domain identifiers clarify that the interfaces are different managed items, even though they have the same IP address.
The
Default Domain
is created automatically. The
Default Domain
includes any items that are not assigned to a custom domain.
Follow these steps:
  1. Log in to the
    NetOps Portal
    Console as a user with the required administrative role rights.
  2. Display the current domains by completing one of the following actions:
    • Select
      Custom Settings: IP Domains
      .
      The
      Manage IP Domains
      page opens and displays the current domains.
    If you have not created any custom IP domains, only the
    Default Domain
    appears in the list.
  3. Create a new domain:
    • Click
      New
      .
      The
      IP Domains Administration
      dialog opens.
  4. Supply information for the following parameters:
    • Domain Name
      Identifies the domain.
    • Description
      (Optional) Describes this domain namespace, such as naming the enterprise that owns it.
    • Device Name Alias
      Indicates the alias to use for a managed device. A device alias is a user-configured name that is applied to the associated managed item in
      NetOps Portal
      . Click Browse to navigate to and import a CSV file of aliases. The CSV file contains a comma-separated list of IP address-to-device alias mappings.
      Aliases that are associated with the primary IP address of a device take precedence over aliases that are associated with any secondary IP addresses. Look for the primary IP address in the Address column of the Inventory Devices list. We recommend always using the primary IP address of the device in the CSV file.
      For example:
      172.24.36.107,Austin Router
      Browse to select the file and click
      Open
      .
      If you include aliases for devices you are managing already, it can take up to 5 minutes to begin synchronizing these aliases with
      NetOps Portal
      .
      To remove an alias, import a CSV file that includes the IP address for the device and a blank alias column. To change an alias, modify the alias entry in the CSV file and reimport the file.
    • Interface Description Override
      Indicates the alternate description to use for an interface. Interface descriptions appear in
      NetOps Portal
      already, but you can provide an alternate description. Click
      Browse
      to navigate to and import a CSV or TXT file of alternate descriptions. The file contains a comma-separated list of values that include the device IP address, interface name, interface description, and alternate interface description (alias) mappings.
      For example:
      172.24.36.107,ethernet_7,vmxnet3 Ethernet Adapter,Connection to Dallas
      Use the primary IP address of the associated device in the CSV or TXT file. Secondary IP addresses are not supported. Look for the primary IP address in the
      Address
      column of the
      Inventory Devices
      list.
      Browse to select the file and click
      Open
      .
      If you include alternate descriptions for interfaces you are managing already, it can take up to 5 minutes to begin synchronizing these descriptions with
      NetOps Portal
      .
      You can use the same alternate interface descriptions for more than one interface.To remove an alternate description, import a CSV or TXT file that includes the IP address for the device, the interface name, the interface description, and a blank alias column. When you remove an alternate description, the original interface description reappears in
      NetOps Portal
      views.
      If you use a spreadsheet program to remove all of the alternate descriptions from a
      CSV
      file, include a column heading for the interface description override column in the imported file. If you do not include this column heading, the original interface descriptions will not reappear in
      NetOps Portal
      views.
      To change a description, modify the alias entry in the
      CSV
      or
      TXT
      file and re-import the file.
    • DNS Settings check box
      If selected, displays the Primary DNS/Port and Secondary DNS/Port options.
    • Primary DNS Address
      Is the IP address of the primary name server for this domain.
    • Primary DNS Port
      Is the port number that the primary name server uses.
    • Secondary DNS Address
      Is the IP address of the secondary name server for this domain. Can be the same as the primary address.
    • Secondary DNS Port
      Is the port number that the secondary name server uses.
  5. Click
    Save
    .The new IP domain appears on the page.
  6. Repeat the steps as required to add more IP domains.
