Configuring 802.1X With Voice Vlan; Enabling Periodic Reauthentication - Cisco 4500M Software Manual

How to Configure 802.1X

Configuring 802.1X with Voice VLAN

To enable 802.1X with voice VLAN feature, perform this task:
Command
Step 1
Switch # configure terminal
Step 2
Switch(config)# interface
interface-id
Step 3
Switch(config-if)# switchport
access vlan vlan-id
Step 4
Switch(config-if)# switchport mode
access
Step 5
Switch(config-if)# switchport voice
vlan vlan-id
Step 6
Switch(config-if)# dot1x
port-control auto
Step 7
Switch(config-if)# end
Step 8
Switch(config)# end
This example shows how to enable 802.1X with voice VLAN feature on Fast Ethernet interface 5/9:
Switch# configure terminal
Switch(config)# interface fastethernet5/9
Switch(config-if)# switchport access vlan 2
Switch(config-if)# switchport mode access
Switch(config-if)# switchport voice vlan 10
Switch(config-if)# dot1x port-control auto
Switch(config-if)# end
Note

Enabling Periodic Reauthentication

You can enable periodic 802.1X client reauthentication and specify how often it occurs. If you do not
specify a time value before enabling reauthentication, the interval between reauthentication attempts is
3600 seconds.
Automatic 802.1X client reauthentication is a per-interface setting and can be set for clients connected
to individual ports. To manually reauthenticate the client connected to a specific port, see the
Reauthenticating a Client Connected to a Port" section on page
To enable periodic reauthentication of the client and to configure the number of seconds between
reauthentication attempts, perform this task:
Command
Step 1
Switch# configure terminal
Step 2
Switch(config)# interface
interface-id
