Problem with configuration of SRW 2016 for 802.1x with Cisco ACS 4.2

[Goran Jelenkovikj]

Dear all,

I have cisco infrastructure with cisco catalyst 2960 and 3560 and 2x ACS 4.2 and 802.1x authentication is work fine.

I tried to add Linksys SRW2016 in the infastructure but I run into a problem.

I did the configuration on ACS same as for all other switches and I configured SRW2016 according maunal for .1x and on log on ACS in FAILED ATTEMPTS I received following error:

Message-Type:          Bad request from NAS

Authen-Failure-Code:  Invalid message authenticator in EAP request

I receked the configuration specialy the Shared Secret and it is OK.

Any idea what is the problem and how to resolve it?

Best regards,

Goran,

That is mostly indicative of a bad shared secret. Can you confirm whether the Linksys switch is in a NDG, and if so, do you have any keys defined for the NDG?

Faisal,

Thank you.

I check the shared secret again and again, and i noticed some small but big differance.

I correct it and now the authentification on port with .1x is OK.

Goran,
