User Guidelines
If only one RADIUS server is configured, it is recommended to use a
deadtime interval of 0.
Setting the deadtime to 0 indicates to the switch that the server should never
be marked dead. This effectively disables features such as critical Voice
VLAN.
If a RADIUS server is currently active and responsive, that server will be used
until it no longer responds. RADIUS servers whose deadtime interval has not
expired are skipped when searching for a new RADIUS server to contact.
Example
The following example specifies a deadtime interval of 60 minutes.
console(config)#radius server auth 192.143.120.123
console(config-auth-radius)#deadtime 60
key
Use the key command to specify the encryption key which is shared with the
RADIUS server. Use the no form of this command to remove the key.
