Configuring The Host Mode - Cisco Catalyst 2950 Software Configuration Manual

Configuring IEEE 802.1x Authentication
Beginning in privileged EXEC mode, follow these steps to set the switch-to-client frame-retransmission
number. This procedure is optional.
Command
Step 1 configure terminal
Step 2 interface interface-id
Step 3
dot1x max-req count
Step 4 end
Step 5
show dot1x interface interface-id
Step 6 copy running-config startup-config
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 authentication process:
Switch(config-if)# dot1x max-req 5

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
To disable multiple hosts on the port, use the no dot1x host-mode multi-host interface configuration
command.
This example shows how to enable a port to allow multiple hosts:
Switch(config)# interface fastethernet0/1
Switch(config-if)# dot1x port-control auto
Switch(config-if)# dot1x host-mode multi-host

Purpose
Enter global configuration mode.
Specify the interface to be configured, and enter interface configuration
mode.
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.
Return to privileged EXEC mode.
Verify your entries.
(Optional) Save your entries in the configuration file.
Purpose
Enter global configuration mode.
Specify the interface 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.
