ACS Authentication issues when added to client group

When my remote site customer adds a new device to an existing client group with a large number of devices, RADIUS authentication to that device fails; authentication is successful if moving that device to a smaller client group. Is there a limit in the number of devices that may be included in a client group? If yes, what is the limit, and why is there no warning or error raised by the ACS 4.1 server when adding a device beyond that limit? We did not have this issue in the previous version ACS 3.1 software.

Thanks for any help you can give


Re: ACS Authentication issues when added to client group

Please check,

ACS---> Network configuration----> NDG (where you have this switch) ----> Edit Properties----> Remove key.

NDG key overwrites aaa client key.

ACS provides the ability to define a key on a Network Device Group (NDG), as well as define a key on an individual NAS within that group. If the key is defined in both places, the NDG key takes precedence over the individual device key.
