Executing NIOS IPAM Sync


Infoblox NIOS software, running on Infoblox appliances, delivers core network services—including DNS, DNSSEC, DHCP, IPAM, HTTP, FTP, TFTP, NTP, and others—that are important to the operation of all IP-based networks. IP address management (IPAM) functionality is built in to Infoblox NIOS software and includes a comprehensive suite of functions that support address allocation, management, and reporting.

You can configure a NetMRI instance to synchronize with the NIOS IPAM database and populate it with the NetMRI IP network discovery data. During a synchronization, device data (IP addresses and other data), subnets/DHCP networks, or both are exported from NetMRI to NIOS through a CSV file. You can run a synchronization immediately or schedule for future times.

NetMRI tracks the last time it has successfully communicated with a device via NMAP (used for fingerprinting), SNMP, and telnet/SSH/HTTP. This timestamp information appears in the Network Explorer > Discovery page in NetMRI. To provide the most accurate possible timestamp, the protocols used to generate the timestamps also include ICMP Ping and NetBIOS communications protocols. Ping and NetBIOS data results are not directly displayed on the Network Explorer > Discovery page. NetMRI uses the maximum timestamp for a given device (i.e. across all protocols) to populate the timestamp value that is sent to NIOS.

For how to configure synchronization, see Configuring IPAM Sync. This section also lists IPAM Sync data fields that are exported from NetMRI to NIOS.

For how to execute a configured NIOS IPAM Sync, see Synchronizing Between NetMRI and NIOS Appliances.

Note

NetMRI supports synchronization of IPv6 subnet and address information between NetMRI and target NIOS systems, to automatically define networks in IPAM. Some subnetworks may not be reported to NIOS during IPAM Sync owing to their addressing being part of MPLS VPNs.

Keep in mind the following to get consistent results of synchronization between NetMRI and NIOS:

  • Network Views: Be aware of overlapping subnets and IP addresses. If you execute IPAM Sync several times, do not export different NetMRI network views to the same NIOS network view. Otherwise, some discovered data may be lost.
  • Device reachability: Once a device became unreachable, it remains visible in NetMRI for some time, but it will not be exported to NIOS. If you see the device in NetMRI, but not in NIOS, check the device interfaces and reachability. Some of the interfaces may become disconnected. Additionally, check if the corresponding device subnet is displayed in the list of subnets in NetMRI.
