Monitoring Sites in the Topology Tab

In Aruba Central (on-premises), the Topology tab in the site dashboard provides a graphical representation of the site including the network layout, and details of the devices deployed, and the health of the WANWide Area Network. WAN is a telecommunications network or computer network that extends over a large geographical distance. uplinks and tunnels.

In Aruba Central (on-premises), the Topology tab does not support Campus controllers and Campus APsCampus APs are used in private networks where APs connect over private links (LAN, WLAN, WAN or MPLS) and terminate directly on controllers. Campus APs are deployed as part of the indoor campus solution in enterprise office buildings, warehouses, hospitals, universities, and so on..

The Topology feature is available for Foundation and Advanced licenses for APs, switches, and gateways.

This section includes the following topics:
