Dead Time—Enter the number of minutes that elapse before a non-
responsive RADIUS server is bypassed for service requests. If the value is 0,
the server is not bypassed.
Key String—Enter the default key string used for authenticating and
encrypting between the device and the RADIUS server. This key must match
the key configured on the RADIUS server. A key string is used to encrypt
communications by using MD5. The key can be entered in Encrypted or
Plaintext form. If you do not have an encrypted key string (from another
device), enter the key string in plaintext mode and click Apply. The
encrypted key string is generated and displayed.
This overrides the default key string if one has been defined.

can be used for communication only on the local network. Only one link
local address is supported. If a link local address exists on the interface,
this entry replaces the address in the configuration.
