Setting The Re-Authentication Number; Enabling Mac Move - Cisco Catalyst 3750-X Software Configuration Manual

Chapter 11 Configuring IEEE 802.1x Port-Based 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.
You should change the default value of this command only to adjust for unusual circumstances such as
Note
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
Step 1
configure terminal
Step 2 interface interface-id
Step 3
dot1x max-reauth-req count
Step 4 end
Step 5
show authentication interface-id
or
show dot1x interface interface-id
Step 6
copy running-config startup-config
To return to the default re-authentication number, use the no dot1x max-reauth-req interface
configuration command.
This example shows how to set 4 as the number of times 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.
This procedure is optional.
Command
configure terminal
authentication mac-move permit
end
