Users Guide

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 failure.

To congure re-transmissions, use the following commands.

• Congure 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.

• Congure 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 Conguring a Quiet Period after a Failed Authentication shows conguration 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.

Conguring 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 congure 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 congure a quiet period, use the following command.

• Congure 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 Conguring and Verifying Port Authentication

The following example shows conguration 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

The bold lines show the new re-transmit interval, new quiet period, and new maximum re-transmissions.
