    • Yellow: The network is unmanaged.
    • Blue: The selected network.
    • GreyGray: The network is currently not available as a NIOS network object.
  • Comment: The information you entered about the network.
  • IPAM Utilization: This information is available for IPv4 networks only. It displays the percentage based on the IP addresses in use divided by the total addresses in the network. For example, in a /24 network, if there are 25 static IP addresses defined and a DHCP range that includes 100 addresses, the total number of IP addresses in use is 125. Of the possible 256 addresses in the network, the IPAM utilization is about 50% for this network. The appliance updates the IPAM utilization data immediately for a network container, but for a network it is updated every 15 minutes.
    The IPAM utilization data is displayed in one of the following colors:
    • Red: The IPAM utilization percentage is above the configured Trigger value.
    • Blue: The IPAM utilization percentage is below the configured Trigger value.
  • Site: The site to which the network belongs. This is one of the predefined extensible attributes.
  • Protocol: Displays whether the network is an IPv4 or IPv6 network.
  • Disabled: Indicates if the network is disabled.
  • Leaf Network: Indicates whether the network is a leaf network or not. A leaf network is a network that does not contain other networks.
  • IPv4 DHCP Utilization: This information is available for IPv4 networks only. It displays the percentage of the total DHCP usage of theIPv4 network. This is the percentage of the total number of DHCP hosts, fixed addresses, reservations, and active leases in the network divided by the total number of IP addresses (excluding IP addresses in the exclusion range) and all DHCP objects in the network. Note that only enabled addresses are included in the calculation. It does not include abandoned addresses or leases. The appliance updates the utilization data approximately every 15 minutes. The utilization data is displayed in one of the following colors:
    • Red: The DHCP resources are 100% utilized.
    • Yellow: The DHCP utilization percentage is over the effective high-water mark threshold.
    • Blue: The DHCP utilization percentage is below the effective low-water mark threshold.
    • Black: The DHCP utilization percentage is at any number other than 100%, or it is not above and below any threshold.
