Hi,
I am actually trying to get MAC-Authentication throught our ACS 3.2 Radius server.My first question is that As I have read any excellent conversation on Cisco forum regarding MAC-Authentication. I have set up everythig on ACS, from user set up, then added the MAC addresses without dotts, like {00095ba3230c}.
in all the required field.
1. Do I need to seup the MAC address list in the AP1200 which is running IOS 12.3(2)JA. In instructions, it says that once you put the mac in the ACS, it will pass to AP1200 automatically, when client device assoiciate to AP. But is does not happenend here, If I setup MAC-filter list, then it work fine, If I don't then client does not get the ip address form DHCP server.
encryption is open with mac and EAP,
I will be happy if some one could help me.
Here is the config from AP1200 below:
aaa new-model
aaa group server radius rad_eap
server 193.x.x.165 auth-port 1645 acct-port 1646
aaa group server radius rad_mac
server 193.x.x.165 auth-port 1645 acct-port 1646
aaa group server radius rad_acct
aaa group server radius rad_admin
aaa group server tacacs+ tac_admin
aaa group server radius rad_pmip
aaa group server radius dummy
aaa group server radius rad_eap2
server 193.x.x.165 auth-port 1645 acct-port 1646
aaa group server radius rad_eap1

aaa group server radius rad_mac2

"Do I need to seup the MAC address list in the AP1200 which is running IOS 12.3(2)JA?"
No.
How do you setup the user profile in ACS? You need to set up a user with user name and the password as the MAC address in the format of xxxxxxxxxxxx.
If you have done that, is there any entry in the successful authentications and failed attemps?

Hi,
Many thanks for oyur reply.
I have done as you have just said that take off the mac filter list from AP1200. I can see the cilent pass the mac authentication in the ACS logs.
Its working fine.

"You need to set up a user with user name and the password as the MAC address in the format of xxxxxxxxxxxx."
Will this work with Cisco ACS version 3.0? I tried entering the client MAC address into the ACS, but it came back with an error saying 'Can not have the username in the password'. Any idea.

I think you are missing the line at the bottom of your config to define the radius server and key. You did setup a username and password under "network configuration" for the AP as a radius client. If not then, under failed attempts on the ACS you'll see "Unknown NAS" error messages. The syntax for the radius server command is as follows:
radius-server host x.x.x.x auth-port 1812 acct-port 1813 key xxxxxx

I'm also doing MAC authentication with the same AP, but with freeradius.
Do you know how to configure the AP so that it sends as
User-name the MAC with dashes ex: e4356-a125-a2345-3556?
Thank you
