ACS 4.2 Preferred EAP Protocol

jialbert — Mon, 11 Mar 2019 04:12:29 GMT

ACS 5.x can configure preferred EAP protocol:

Preferred EAP protocol

Select the preferred EAP protocol from the following options available:

•EAP-FAST

•PEAP

•LEAP

•EAP-TLS

•EAP-MD5

This option helps ACS to be flexible to work with old supplicants (end devices) which are not capable of sending No-Acknowledgement, when a particular protocol is not implemented. You can use this option to place a particular protocol first in list of protocols that is being negotiated with device so that the negotiation is successful.

Any way to configure that in ACS 4.2?

Thanks.

As such, there is no option like this in ACS 4.x.

Which protocol are you concerned with?

ACS 4 works with most older supplicants especially ones that LEAP as well.

In ACS 4 if LEAP is enabled, its the first protocol that is proposed.

ACS 5 will always propose EAP-TLS even if LEAP is enabled unless configured to change that.

We want to make EAP-MD5 the first to use. Supplicants are some switches for MAC based Authentication.

Any way can make it for ACS 4.2 such as some internal cli configure, window registery table editing or tweak?

Thanks.
