Administrator Guide

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:

• after 90 seconds and a maximum of 10 times for an unresponsive supplicant

• re-transmits an EAP Request Identity frame
