I think i have a simple question: I wan't do activate 802.1x on our siwtches(about 800 devices: 6500,3500,3600,4500,...). We use for telnet Tacacs for authentication,authorization and accounting. For 802.1x i need to configure raidius on the switches. So my question is: Can i run Radius and Tacacs
for the same device or do i have to cahnge the telnet-authenticatoin/authorization to Radius. In the NetworkDeviceGroup configuration on ACS4.1 i can only define Tacacs or Radius for the authentication type for one device.
