What are the methods through which Instant AP contacts the managed-mode server?

Aruba Employee

Environment : This applies to all Instant models running OS 6.2.1.0-3.4.x and above.

 

In managed-mode, Instant can contact the server using 2 methods.

  • FTP
  • FTPS

Note: Instant uses FTPS explicit mode still using TCP port 21. When the Instant boots up it performs a GET operation to retrieve the configuration file from the server.

Below is the sample config output of Instant trying to contact the server. The debug was performed on Instant.

216.12.234.15 is the dummy server ip.

00:24:6c:c8:68:98# debug pkt match ip 216.12.234.15
00:24:6c:c8:68:98# debug pkt type all
00:24:6c:c8:68:98# debug pkt dump
If source, destination or target IP is 216.12.234.15
AND packet is of type ARP OR PPPoE OR Mobility OR ICMP OR TCP OR UDP OR GRE OR DHCP OR DNS OR RADIUS OR HTTP OR HTTPS
Press 'q' to quit.
