Configuring Request Identity Re-transmissions
If the authenticator sends a Request Identity frame, but the supplicant does not respond, the authenticator
waits 30 seconds and then re-transmits the frame. The amount of time that the authenticator waits before
re-transmitting and the maximum number of times that the authenticator re-transmits are configurable.
To configure the amount of time that the authenticator waits before re-transmitting an EAP Request
Identity frame:
To configure a maximum number of Request Identity re-transmissions:
Figure 7-7 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.

If the supplicant fails the authentication process, the authenticator sends another Request Identity frame
after 30 seconds by default, but this period can be configured.
To configure the quiet period after a failed authentication:
Note: There are several reasons why the supplicant might fail to respond; the supplicant might have been
booting when the request arrived, there might be a physical layer problem, or the supplicant might not be
802.1x capable.
