Chapter 10 Configuring IEEE 802.1x Port-Based Authentication
Configuring 802.1x Authentication
Beginning in privileged EXEC mode, follow these steps to set the switch-to-client frame-retransmission
number. This procedure is optional.
To return to the default retransmission number, use the no dot1x max-req interface configuration
command.
This example shows how to set 5 as the number of times that the switch sends an EAP-request/identity
request before restarting the authentica tion process:
Switch(config-if)# dot1x max-req 5
Setting the Re-Authentication Number
You can also change the number of times that the switch restarts the authentication process before the
port changes to the unauthorized state.
Note You should change the default value of this command only to adjust for unusual circumstances such a s
unreliable links or specific behavioral problems with certain clients and authentication servers.
Beginning in privileged EXEC mode, follow these steps to set the re-authentication number. This
procedure is optional.
Command Purpose
Step 1 configure terminal Enter global configuration mode.
Step 2 interface interface-id Specify the port to be configured, and enter interface configuration mode.
Step 3 dot1x max-reauth-req count Set the number of times that the switch sends an EAP-request/identity
frame to the client before restarting the authentication process. The range
is 1 to 10; the default is 2.
Step 4 end Return to privileged EXEC mode.
Step 5 show authentication interface
interface-id
or
show dot1x interface interface-id
Verify your entries.
Step 6 copy running-config startup-config (Optional) Save your entries in the configuration file.
Command Purpose
Step 1 configure terminal Enter global configuration mode.
Step 2 interface interface-id Specify the port to be configured, and enter interface configuration mode.
Step 3 dot1x max-reauth-req count Set the number of times that the switch restarts the authentication process
before the port changes to the unauthorized state. The range is 0 to 10; the
default is 2.
Step 4 end Return to privileged EXEC mode.
