Connecting to Aruba Central

ArubaOS-CX switch downloads the location of Aruba Central server using:

  • Command-line interface (CLI).

  • Aruba Activate server.
  • DHCP options provided during ZTP.

DHCP servers are used to connect to Central on-premise management.

If switch is unable to connect to Activate server, it retries to establish connection in exponential back off of 1s, 2s, 8s, 16s, 32s, 64s, 128s, and 256s. After the maximum back off of 256s, switch retries happen for every 5 minutes.


If the Network Time Protocol (NTP) is not enabled on the switch, it will synchronize the system time with the Activate server.
