Topology Maps
Topology Maps help network and IT administrators to find the interconnections and relationships between devices in an IT infrastructure. With an overall view of the network, administrators can better visualize the dependencies of devices. Filters, search, and toggles can be used to narrow down or customize the map. Multiple topology views can also be created.
Scans of the whole IT infrastructure is performed nightly to update the map.
Data collection
-
SNMP network devices by performing SNMP walks against the LLDP and CDP MIBs on each monitored network device. Enable LLDP or CDP on network devices to expose this data.
-
Fabric network devices topology data directly from the Fabric APIs used for discovery and provisioning.
-
VMware infrastructure topology data from the VMWare APIs used for discovery and provisioning.
Note: If you enable LLDP/CDP or add Fabric integrations, the topology map will not be updated with new data until after the next nightly scan.
