Enabling Mac Move; Enabling Mac Replace - Cisco Catalyst 2975 Software Configuration Manual

Configuring 802.1x Authentication
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
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
Step 1 configure terminal
Step 2
authentication mac-move permit
Step 3 end
Step 4 show running-config
Step 5 copy running-config startup-config
This example shows how to globally enable MAC move on a switch:
Switch(config)# authentication mac-move permit

Enabling MAC Replace

MAC replace allows a host to replace an authenticated host on a port.
