.
Auth port
Enter the authorization port number of the external RADIUS server within the range of 1–65,535.
The default port number is 1812.
Accounting
port
Enter the accounting port number within the range of 1–65,535. This port is used for sending
accounting records to the RADIUS server. The default port number is 1813.
Shared key
Enter a shared key for communicating with the external RADIUS server.
Retype key
Re-enter the shared key.
Timeout
Specify a timeout value in seconds. The value determines the timeout for one RADIUS request. The
IAP retries to send the request several times (as configured in the
Retry count
) before the user
gets disconnected. For example, if the
Timeout
is 5 seconds,
Retry counter
is 3, user is
disconnected after 20 seconds. The default value is 5 seconds.
Retry count
Specify a number between 1 and 5. Indicates the maximum number of authentication requests that
are sent to the server group, and the default value is 3 requests.
RFC 3576
Select
Enabled
to allow the IAPs to process RFC 3576-compliant Change of Authorization (CoA) and
disconnect messages from the RADIUS server. Disconnect messages cause a user session to be
terminated immediately, whereas the CoA messages modify session authorization attributes such
as data filters.
NAS IP
address
Allows you to configure an arbitrary IP address to be used as RADIUS attribute 4, NAS IP Address,
without changing source IP Address in the IP header of the RADIUS packet.
NOTE:
If you do not enter the IP address, the VC IP address is used by default when
Dynamic
RADIUS Proxy
is enabled.
NAS
Identifier
Allows you to configure strings for RADIUS attribute 32, NAS Identifier, to be sent with RADIUS
requests to the RADIUS server.
Dead Time
Specify a dead time for authentication server in minutes.
When two or more authentication servers are configured on the IAP and a server is unavailable, the
dead time configuration determines the duration for which the authentication server would be
available if the server is marked as unavailable.
Dynamic
RADIUS
proxy
parameters
Specify the following dynamic RADIUS proxy (DRP) parameters:
l
DRP IP—IP address to be used as source IP for RADIUS packets.
l
DRP Mask—Subnet mask of the DRP IP address.
l
DRP VLAN—VLAN in which the RADIUS packets are sent.
l
DRP Gateway—Gateway IP address of the DRP VLAN.
