Cisco ACS 5.3 and ProCurve 2510 with 802.1X and Mac-auth

Level 1
Level 1


I am having difficulties implementing Mac-auth on selected ports between an HP ProCurve 2510 and Cisco ACS 5.3.The 802.1x works just fine, but for selected ports I need to implement port-access with MAC-based authentication instead of regular 802.1X (yeah, I know, but this line of ProCurve switches only support one auth-mechanism per port!).

The switch successfully forwards interesting MAC-auth requests for authentication to the ACS with CHAP/MD5, but the ACS reports this:

The ACS is configured to use the Internal Hosts database, where the client computer is configured like this;

Anyone encountered this, or has any suggestions?

I think it is as it says. CHAP/MD5 is not supported on the identity store. Can you try with PAP?



with MAB you need "host-lookup". Nothing else.




host-lookup ist already activated.. the Problem is the Switch.. the switch is sending CHA/MD5 pakets to the acs...

i installed a newer firmware on my hp switches and now it works
