Creating and maintaining a domain with all devices properly discovered is the key to keep system data up-to-date to guarantee data accuracy and further utilize advanced features, such as path and map.

Domain Manager provides an overview of how devices are discovered, where you can get started to fix all the access issues. The devices listed in each category are updated as soon as a discovery task is completed, including both the on-demand discovery and the scheduled discovery. It’s recommended to check and maintain in the Domain Manager at least once a week or whenever a discovery task is completed.

1.In the Domain Management page, click Operations > Domain Manager from the quick access toolbar.

2.Resolve the issues under the following categories:

▪Unknown IP — the IP addresses that cannot be accessed via Telnet/SSH and SNMP during a discovery.

▪Discovered Devices — the devices discovered successfully during a discovery.

▪Missed Devices — the devices existing in the current domain but failed to be verified during a discovery.

▪Discovered by SNMP — the devices accessed by SNMP but failed to be accessed via SSH/Telnet.

▪Unknown SNMP sysObjectID — the devices whose sysObjectIDs are not defined in the Vendor Model table.

▪Unclassified Network Devices — the devices whose types are not supported, or not recognized due to unknown sysObjectIDs.

▪MPLS Cloud — used to enable A-B path across a vendor supplied MPLS network.
