different NAS types with different parameters

hey list, we have switches from enterasys and access points from cisco, now we have configured the parameters like this example in the users file: DEFAULT LDAP-Group == "CN=xadmins,CN=users,DC=isalab,DC=local" Filter-ID == "Enterasys:version=1:policy=xadmins", Tunnel-Type:1 = 13, Tunnel-Medium-Type:1 = 6, Tunnel-Private-Group-ID:1 = 1, Reply-Message = "Welcome %u", Fall-Through = No so with this entry the enterasys switch also gets the parameters from the aironet and on the other way the same! is this the right way or is there an other possibility to give the differernt types of NAS different parameters? thanks mIke
