Upload a List of Subnets with Only Static IP Addresses

Assist IoT Security in discovering static IP devices by uploading a CSV file containing a list of subnets with static IP addresses.
In the case where an entire subnet consists of static IP addresses, it’s more efficient to add a subnet and define it as having static IP addresses than adding numerous static IP devices individually. When you have multiple subnets with static IP addresses, you can upload all of them in a CSV file at once.
After you provide IoT Security with a subnet configuration specifying that it has static IP addresses and then IoT Security detects traffic from a device in that subnet, it considers the device a static IP device. Using the IP address as the device ID (instead of a MAC address), it adds the device to its inventory. IoT Security adds static IP devices to its inventory in this manner only for devices that are not discovered through other detection mechanisms such as ARP logs.
If you later remove a static IP subnet after IoT Security added static IP devices for this subnet to its inventory, IoT Security reverses this action and automatically removes them from its inventory.
  1. Navigate to the Subnets page (
    Network
    Subnets
    ) and then click
    Add
    Upload subnets
    .
  2. Click the link to download the CSV template.
  3. Fill out the template with subnet information.
    Enter the following for each subnet you want to upload:
    prefix
    : Enter the IP address of the subnet in dot-decimal notation and its netmask in CIDR notation (example, 10.1.1.0/24). This appears on the Subnets page, and for a device in this subnet, the subnet and netmask appear on the Devices and Device Details pages.
    vlan
    : (Optional) Enter a VLAN ID. If entered, this also appears on the Subnets page, and for a device in this subnet, it appears on the Devices and Device Details pages.
    description
    : (Optional) Enter a description of the subnet/VLAN, perhaps noting the type of devices for which it’s intended. These special characters are not allowed in the description field: ~ ` ! # $ % ^ & * + = { } [ ] | \ < > ? This description only appears on the Subnets page.
    static
    : Enter
    yes
    to define this as a subnet containing static IP addresses. When IoT Security discovers a device from a user-configured static IP subnet in a different L2 domain from the firewall and adds it to its inventory, the Source column on the Devices page shows
    User-Configured
    . (Leave it blank if you do not want the subnet to be static).
    monitored
    : Enter
    yes
    if you want IoT Security to provide device profiling, behavioral analysis, and risk monitoring of the devices in this subnet. Leave it blank if you only want IoT Security to detect the devices in the subnet and perform a simplified device identity analysis. Based on this field, the IoT Security portal displays the subnet either on the
    Subnets
    Monitored
    or
    Subnets
    Unmonitored
    tab and provides the appropriate level of device monitoring, analysis, and protection.
    The
    Add a subnet
    option does not provide an option to specify a subnet as monitored or unmonitored. IoT Security automatically classifies an added subnet as monitored. However, you can change its classification after you add it by selecting the subnet and clicking
    Stop Monitoring
    .
  4. Upload the CSV file.
    Return to the Subnets page, click
    Add
    Upload subnets
    , choose or drag the completed CSV file onto the space in the dialog box, and then click
    Upload
    . Return to the Subnets page, click
    Add
    Upload subnets
    , choose or drag the completed CSV file onto the space in the dialog box, and then click
    Upload
    .
    If IoT Security previously detected network activity from an IP address in one of the uploaded subnets, it now considers it a static IP address and automatically adds a static IP device to the inventory on the Devices page. Similarly, if IoT Security later detects traffic from an IP address in one of these subnets, it automatically adds an entry to the inventory at that time.
    It can take several minutes for new entries to appear on the Devices page.
