2.6.5 Configuring Mixed Mode Security
Mixed mode security allows a single access point to transmit and receive
data with mobile units operating with different encryption algorithms. In
mixed mode, additional APs are not needed to support mobile units simply
because they are using different encryption schemes. 128-bit WEP, Kerberos
and EAP-TLS can be used together to provide mixed mode security.
To configure mixed mode security:
1. In the access point System Summary screen, set the Shared Key option
to Enabled and the Key Width to 128 bit . Click [F1] to save the settings.
2. From the Special Functions Menu screen, select the Configure
Kerberos option. From the Configure Kerberos Authentication screen,
set the Kerberos option to Enabled . Enter the KSS Name/IP address.
3. Click [F1] to save the settings. Reboot.
If the Key Width is not set to 128 bit , an error message displays (once the
settings are saved and Kerberos is enabled) stating 128 bit must be enabled.
Consequently, 128 bit is required for mixed mode security to be used. When
Kerberos is set, the key width defaults to 128-bit.
