Authentication
Timeout Defines the maximum time (between 30 - 120 seconds)
allowed for SSH authentication to occur before executing a
timeout. The minimum permissible value is 30 seconds.
SSH Keepalive
Interval The SSH Keepalive Interval defines a period (in seconds)
after which if no data has been received from a client,
SSH sends a message through the encrypted channel to
request a response from the client. The default is 0, and
no messages will be sent to the client until a non-zero
value is set. Defining a Keepalive interval is important,
otherwise programs running on a server may never notice
if the other end of a connection is rebooted.
Local The access point verifies the authentication connection.
Radius Designates that a RADIUS server is used in the
authentication credential verification. If using this option,
the connected PC is required to have its RADIUS
credentials verified with an external RADIUS server.
Additionally, the RADIUS Server’s Active Directory should
have a valid user configured and have a PAP based
Remote Access Policy configured for RADIUS Admin
Authentication to work.
Radius Server IP Specify the numerical (non DNS name) IP address of the
Remote Authentication Dial-In User Service (RADIUS)
server. RADIUS is a client/server protocol and software
enabling remote-access servers to communicate with a
server used to authenticate users and authorize access to
the requested system or service.
Port Specify the port on which the server is listening. The
RADIUS server typically listens on ports 1812 (default
port).
Shared Secret Define a shared secret for authentication on the server.
The shared secret is required to be the same as the
shared secret defined on the RADIUS server. Use shared
secrets to verify RADIUS messages (with the exception of
the Access-Request message) sent by a RADIUS-enabled
device configured with the same shared secret.
Apply the qualifications of a well-chosen password to the
generation of a shared secret. Generate a random, case-
sensitive string using letters and numbers. The default is
admin123.
Change Admin
Password Click the Change Admin Password button to display a
screen for updating the AP administrator password. Enter
and confirm a new administrator password as required.
