Figure 5-6. Verifying 802.1X Interface Configuration
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.
Note: There are several reasons why the supplicant might fail to respond; the supplicant might have been
booting when the request arrived, or there might be a physical layer problem.
