NOTE: There are several reasons why the supplicant might fail to respond; for example, the
supplicant might have been booting when the request arrived or there might be a physical layer
problem.
To configure re-transmissions, use the following commands.
• Configure the amount of time that the authenticator waits before re-transmitting an EAP Request
Identity frame.
INTERFACE mode
dot1x tx-period number
The range is from 1 to 65535 (1 year)
The default is 30.
• Configure a maximum number of times the authenticator re-transmits a Request Identity frame.
INTERFACE mode
dot1x max-eap-req number
The range is from 1 to 10.
The default is 2.
The example in Configuring a Quiet Period after a Failed Authentication shows configuration information
for a port for which the authenticator re-transmits an EAP Request Identity frame after 90 seconds and
re-transmits a maximum of 10 times.
Configuring a Quiet Period after a Failed Authentication
If the supplicant fails the authentication process, the authenticator sends another Request Identity frame
after 30 seconds by default, but you can configure this period.
NOTE: The quiet period (dot1x quiet-period) is a transmit interval for after a failed
authentication; the Request Identity Re-transmit interval (dot1x tx-period) is for an unresponsive
supplicant.
To configure a quiet period, use the following command.
• Configure the amount of time that the authenticator waits to re-transmit a Request Identity frame
after a failed authentication.
INTERFACE mode
dot1x quiet-period seconds
The range is from 1 to 65535.
The default is 60 seconds.
Example of Configuring and Verifying Port Authentication
The following example shows configuration information for a port for which the authenticator re-
transmits an EAP Request Identity frame:
