machine MAC authentication by ACS


I have 1 AP 1240 & ACS 4.1 Solution Engine.

I want to authenticate internal users by their MAC addresses (that is created into ACS database) after selecting appropriate SSID from the AP.

Let me give you an idea of the setup & config:

I have a DHCP server in the network from where users will get IP addresses.

I have created 2 VLAN's in the switch & made the port as "Trunk" that is connected with AP. VLAN 1 as native VLAN (AP & ACS is asigned ip addresses of native vlan range) & VLAN 2 for Internal Users.

Radio interfaces are mapped to the VLAN id & SSID is mapped with VLAn as well in AP.

MAC addresses are confiured into ACS (without any space, comma, special character..the mac addreses are put manually in the ACS to avoid the generation of any phantom character).

The problem is "USers are not getting IP addreses from the dhcp pool created in the switch" after selecting the SSID.

Please ry to help me out in this...


Re: machine MAC authentication by ACS

You can try to disable aironet extensions & enable the SSID as guest mode SSID. Also, try to change the datarates to enable. Else, configure MAC authentication and disable SSID as guest mode SSID.
