Concept Guide

In the following example, the bold lines show that 802.1X is enabled.
DellEMC#show running-config | find dot1x
dot1x authentication
!
[output omitted]
!
interface GigabitEthernet 2/1
no ip address
dot1x authentication
no shutdown
!
DellEMC#
To view 802.1X conguration information for an interface, use the show dot1x interface command.
In the following example, the bold lines show that 802.1X is enabled on all ports unauthorized by default.
DellEMC#show dot1x interface GigabitEthernet 2/1/
802.1x information on Gi 2/1/:

Conguring 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 congured.
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 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.
