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:
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.
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.
