Security Commands 1013
This command sets the limit for retring failed authentications for RADIUS.
The switch attempts authentication based on the selected method and if
authentication returns an error (as opposed to a failure), the next
authentication method is attempted regardless of this setting.
For example, if one or multiple RADIUS servers are configured and no
RADIUS server responds to the authentication message, RADIUS returns an
error and the next authentication method is attempted even when the retry
parameter is configured to a value larger than 1.
Example
The following example configures the switch to allow IEEE 802.1X
supplicants to fail authentication (e.g., enter incorrect passwords) three times
before invoking the quiet timer on the interface.

console(config)#authentication enable
console(config)#interface gi1/0/3
