Level
Type
reduce the number of exchange packets between the W-IAP and authentication
server.
NOTE: Instant supports the configuration of primary and backup authentication
servers in an EAP termination enabled SSID.
NOTE: If you are using LDAP for authentication, ensure that AP termination is
configured to support EAP.
Authentication
server 1 and
Authentication
server 2
Select any of the following options from the Authentication server 1 drop-down
list:
l Select an authentication server from the list if an external server is already
configured. To modify the server parameters, click Edit.
l Select New to add a new server.
For information on configuring external servers, see Configuring an External
Server for Authentication on page 164.
l To use an internal server, select Internal server and add the clients that are
required to authenticate with the internal RADIUS server. Click the Users link to
add the users. For information on adding a user, see Managing W-IAP Users on

Load
balancing

Reauth
interval
Specify a value for Reauth interval. When set to a value greater than zero, APs
periodically reauthenticate all associated and authenticated clients.
If the reauthentication interval is configured:
l On an SSID performing L2 authentication (MAC or 802.1X authentication)—When
reauthentication fails, the clients are disconnected. If the SSID is performing only
MAC authentication and has a pre-authentication role assigned to the client, the
client will get a post-authentication role only after a successful reauthentication.
If reauthentication fails, the client retains the pre-authentication role.
l On an SSID performing both L2 and L3 authentication (MAC with captive portal
authentication)—When reauthentication succeeds, the client retains the role that
is already assigned. If reauthentication fails, a pre-authentication role is
assigned to the client.
l On an SSID performing only L3 authentication (captive portal authentication)—
When reauthentication succeeds, a pre-authentication role is assigned to the
client that is in a post-authentication role. Due to this, the clients are required to
go through captive portal to regain access.
