Configuring Request Identity Re-Transmissions
When the authenticator sends a Request Identity frame and the supplicant does not respond, the authenticator waits for 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 can be configured.
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 problem.
To configure re-transmissions, use the following commands.
Configure 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.
Configure the 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 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 for 10 times.
Configuring 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. You can configure this period.
NOTE:
The quiet period (dot1x quiet-period) is the transmit interval after a failed authentication; the Request
Identity Re-transmit interval (dot1x tx-period) is for an unresponsive supplicant.
To configure a quiet period, use the following command.
Configure 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.
The 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 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.
Forcibly Authorizing or Unauthorizing a Port
The 802.1X ports can be placed into any of the three states:
ForceAuthorized an authorized state. A device connected to this port in this state is never subjected to the
authentication process, but is allowed to communicate on the network. Placing the port in this state is same as disabling
802.1X on the port.
