802.1x Authentication Configuration Guidelines
These section has configuration guidelines for these features:
•
802.1x Authentication, page 10-35
•

page 10-37
•
MAC Authentication Bypass, page 10-37
•

802.1x Authentication
These are the 802.1x authentication configuration guidelines:
• When 802.1x authentication is enabled, ports are authenticated before any other Layer 2 or Layer 3
features are enabled.
•
If you try to change the mode of an 802.1x-enabled port (for example, from access to trunk), an error
message appears, and the port mode is not changed.
Number of seconds between re-authentication
attempts 3600 seconds.
Re-authentication number 2 times (number of times that the switch restarts the authentication process
before the port changes to the unauthorized state).
Quiet period 60 seconds (number of seconds that the switch remains in the quiet state
following a failed authentication exchange with the client).
Retransmission time 30 seconds (number of seconds that the switch should wait for a response to
an EAP request/identity frame from the client before resending the request).
Maximum retransmission number 2 times (number of times that the switch will send an EAP-request/identity
frame before restarting the authentication process).
Client timeout period 30 seconds (when relaying a request from the authentication server to the
client, the amount of time the switch waits for a response before resending the
request to the client.)
Authentication server timeout period 30 seconds (when relaying a response from the client to the authentication
server, the amount of time the switch waits for a reply before resending the
response to the server.)
You can change this timeout period by using the dot1x timeout
server-timeout interface configuration command.
Guest VLAN None specified.
Inaccessible authentication bypass Disabled.
Restricted VLAN None specified.
Authenticator (switch) mode None specified.
MAC authentication bypass Disabled.
