> # About the Default RADIUS Server Encryption Type and Preshared Key

> You need to configure the RADIUS preshared key to authenticate the switch to the RADIUS server. The length of the key is restricted to 64 characters and can include any printable ASCII characters (white spaces are not allowed). You can configure a global key to be used for all RADIUS server configurations on the switch.

> You can override this global key assignment by explicitly using the key option when configuring an individual RADIUS server.
