It might depend on the type of controller you have but you can determine by executing the following command from your controller :
This is the output from an M3 controller and the default is 25 concurrent web sessions
(aruba-controller) #show web-server
Web Server Configuration
------------------------
Parameter Value
--------- -----
Cipher Suite Strength high
SSL/TLS Protocol Config sslv3 tlsv1
Switch Certificate default
Captive Portal Certificate default
Management user's WebUI access method username/password
User session timeout <30-3600> (seconds) 900
Maximum supported concurrent clients <25-400> 25
But for the CLI/SSH session the maximum I believe it is 5.
Hope this helps
Thanks
