IPAM is capable of using both SNMP and ICMP scanning to continuously determine the status of your monitored network. The Subnet Scan Settings view allows you to select how IPAM automatically scans your network for changes.

To configure Orion IPAM subnet scan settings:

  1. Click IP Addresses in the menu bar.
  2. Click IPAM Settings.
  3. Click Manage Subnet Scan Settings.

  4. Provide an appropriate value for the Transient Period. The Transient period must be a value from .2 to 340 days.

    IPAM continuously scans all managed IP addresses on your network. If a device fails to respond to any SNMP or ICMP requests for the period of time designated as the Transient Period, Orion IPAM changes the status of the unresponsive IP address from Used to Available. Any associated custom attribute will be overwritten.

    You can assign Transient scan intervals on a per subnet basis from the Edit Subnet window.

  5. Enter the maximum number of simultaneous scans you want IPAM to attempt.
  6. ICMP is used by default to scan your network subnets for changes. Complete the following steps to configure ICMP:
    1. Provide an appropriate number of Pings per address.
    2. Designate both the Delay between Pings and the Ping Timeout, in ms, for ICMP requests on your network.
  7. If you want to collect device details using SNMP to scan your network subnets, complete the following steps:
    1. Check Enable SNMP Scanning in the SNMP Scanning section.
    2. Provide an appropriate number of SNMP Retries.
    3. Designate the SNMP Timeout for SNMP requests on your network. The timeout value is measured in milliseconds.
    4. Enable SNMP neighbor scanning.
  8. Click Save.

You can disable scanning on a per subnet basis. For more information about editing subnet properties, see Editing Subnets.
