NOTE: There are several reasons why the supplicant might fail to respond; for example, thesupplicant might have been booting when the request arrived or there might be a physical layerproblem.To configure re-transmissions, use the following commands.• Configure the amount of time that the authenticator waits before re-transmitting an EAP RequestIdentity frame.INTERFACE modedot1x tx-period numberThe 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 modedot1x max-eap-req numberThe range is from 1 to 10.The default is 2.The example in Configuring a Quiet Period after a Failed Authentication shows configuration informationfor a port for which the authenticator re-transmits an EAP Request Identity frame after 90 seconds andre-transmits a maximum of 10 times.Configuring a Quiet Period after a Failed AuthenticationIf the supplicant fails the authentication process, the authenticator sends another Request Identity frameafter 30 seconds by default, but you can configure this period.NOTE: The quiet period (dot1x quiet-period) is a transmit interval for after a failedauthentication; the Request Identity Re-transmit interval (dot1x tx-period) is for an unresponsivesupplicant.To configure a quiet period, use the following command.• Configure the amount of time that the authenticator waits to re-transmit a Request Identity frameafter a failed authentication.INTERFACE modedot1x quiet-period secondsThe range is from 1 to 65535.The default is 60 seconds.Example of Configuring and Verifying Port AuthenticationThe 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 supplicant82 802.1X
