Setting The Re-Authentication Number; Configuring The Host Mode - Cisco ME 3400 Software Configuration Manual

Configuring IEEE 802.1x Authentication

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.
Command
Step 1 configure terminal
Step 2 interface interface-id
Step 3 dot1x max-reauth-req count
Step 4 end
Step 5
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

Configuring the Host Mode

Beginning in privileged EXEC mode, follow these steps to allow multiple hosts (clients) on an IEEE
802.1x-authorized port that has the dot1x port-control interface configuration command set to auto.
This procedure is optional.
Command
Step 1
configure terminal
Step 2 interface interface-id
Step 3 dot1x host-mode multi-host
Step 4 end
Step 5
show dot1x interface interface-id
Step 6
copy running-config startup-config

Purpose
Enter global configuration mode.
Specify the port to be configured, and enter interface configuration mode.
Set the number of times that the switch restarts the authentication process
before the port changes to the unauthorized state. The range is 1 to 10; the
default is 2.
Return to privileged EXEC mode.
Verify your entries.
(Optional) Save your entries in the configuration file.
Purpose
Enter global configuration mode.
Specify the port to which multiple hosts are indirectly attached, and enter
interface configuration mode.
Allow multiple hosts (clients) on an IEEE 802.1x-authorized port.
Make sure that the dot1x port-control interface configuration command
set is set to auto for the specified interface.
Return to privileged EXEC mode.
Verify your entries.
(Optional) Save your entries in the configuration file.
