5. Configure the Advanced
authentication server.
MU Timeout Define the time (between 1- 60 seconds) for the switch's retransmission of EAP-
Request packets. The default is 5 seconds.
MU Max Retries Specify the maximum number of times the switch retransmits an EAP-Request
frame to the client before it times out the authentication session. The default is 3
retries, with a maximum of 100 supported.
6. Refer to the Status field for the current state of the requests made from applet. This field displays error
messages if something goes wrong in the transaction between the applet and the switch.
7. Click OK to use the changes to the running configuration and close the dialog.
8. Click Cancel to close the dialog without committing updates to the running configuration.
Configuring Kerboros
Kerberos (designed and developed by MIT) provides strong authentication for client/server applications
using secret-key cryptography. Using Kerberos, a MU must prove its identity to a server (and vice versa)
across an insecure network connection. Once a MU and server prove their identity, they can encrypt all
communications to assure privacy and data integrity. Kerberos can only be used with Motorola clients.
CAUTION: Kerberos makes no provisions for host security. Kerberos assumes it is
running on a trusted host with an untrusted network. If host security is compromised,
Kerberos is compromised as well
To configure a Kerberos authentication scheme for a WLAN:
1. Select Network > Wireless LANs
2. Select an existing WLAN from those displayed within the
3. Click the Edit button.
A WLAN screen displays with the WLAN's existing configuration. Refer to the
Encryption columns to assess the WLAN's existing security configuration.
4. Select the Kerberos button from within the Authentication field.
NOTE: Kerberos requires at least one encryption scheme be enabled (WEP 128 or other).
If neither WEP 128 or KeyGuard is enabled, WEP 128 will automatically be enabled for
use with Kerberos.
