Resetting The Ieee 802.1X Configuration To The Default Values - Cisco Catalyst 2950 Software Configuration Manual

Configuring IEEE 802.1x Authentication
Beginning in privileged EXEC mode, follow these steps to enable the optional guest VLAN behavior
and to configure a guest VLAN. This procedure is optional.
Command
Step 1 configure terminal
Step 2 dot1x guest-vlan supplicant
Step 3
interface interface-id
Step 4
switchport mode access
Step 5 dot1x port-control auto
Step 6 dot1x guest-vlan vlan-id
Step 7 end
Step 8
show dot1x interface interface-id
Step 9 copy running-config startup-config
To disable the optional guest VLAN behavior, use the no dot1x guest-vlan supplicant global
configuration command. To remove the guest VLAN, use the no dot1x guest-vlan interface
configuration command. The port returns to the unauthorized state.
This example shows how enable the optional guest VLAN behavior and to specify VLAN 5 as an IEEE
802.1x guest VLAN:
Switch(config)# dot1x guest-vlan supplicant
Switch(config)# interface gigabitethernet0/1
Switch(config-if)# dot1x guest-vlan 5

Resetting the IEEE 802.1x Configuration to the Default Values

Beginning in privileged EXEC mode, follow these steps to reset the IEEE 802.1x configuration to the
default values.
Command
Step 1
configure terminal
Step 2 interface interface-id
Step 3 dot1x default
Step 4 end
Step 5
show dot1x interface interface-id
Step 6 copy running-config startup-config
