Aruba – lost WPA Passphrase

Issue

The WPA Passphrase for a WiFi network (Aruba) had been forgotten.

Resetting it would be painful due to the number of connected devices.

The WPA Passphrase is not visible from the Virtual Controller GUI.

Resolution

Connect to the Virtual Controller via SSH.

Run the following command to disable encrypted display.

Note: this does not display unencrypted passwords for admin logins.

AP1-X500-Comms-c8:ba:d6#  show run no-encrypt

Find the relevant SSID profile, and the WPA-Passphrase will be shown in clear text, for example:

wlan ssid-profile "X500 Guest"
enable
index 1
type guest
essid "X500 Guest"
wpa-passphrase GiveMeInternet123!!!
opmode wpa2-psk-aes
max-authentication-failures 0
vlan 20
rf-band all
captive-portal disable
dtim-period 1
broadcast-filter arp
dmo-channel-utilization-threshold 90
local-probe-req-thresh 0
max-clients-threshold 64

Sorted!

For info, the Aruba was running ArubaOS (MODEL: 315), Version 6.5.4.9.
