Chapter 11 Configuring IEEE 802.1x Port-Based Authentication
Configuring 802.1x Authentication
This example shows how to set 5 as the number of times that the switch sends an EAP-request/identity
request before restarting the authentication 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 as
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.
To return to the default re-authentication number, use the no do
t1x max-reauth-req interface
configuration command.
This example shows how to set 4 as the number of ti
mes that the switch restarts the authentication
process before the port changes to the unauthorized state:
Switch(config-if)# dot1x max-reauth-req 4
Enabling MAC Move
MAC move allows an authenticated host to move from one port on the switch to another.
Beginning in privileged EXEC mode, follow these steps to globally enable MAC move on the switch.
Thi
s 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 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.
Step 5
show authentication interface-id
or
show dot1x interface int
erface-id
Verify your entries.
Step 6
copy running-config startup-config (Optional) Save your entries in the configuration file.
