Configuring A Restricted Vlan - Cisco 3032 Software Configuration Manual

Configuring 802.1x Authentication
This example shows how to set 3 as the quiet time on the switch, to set 15 as the number of seconds that
the switch waits for a response to an EAP-request/identity frame from the client before re-sending the
request, and to enable VLAN 2 as an IEEE 802.1x guest VLAN when an 802.1x port is connected to a
DHCP client:
Switch(config-if)# dot1x timeout quiet-period 3
Switch(config-if)# dot1x timeout tx-period 15
Switch(config-if)# dot1x guest-vlan 2

Configuring a Restricted VLAN

When you configure a restricted VLAN on a switch stack or a switch, clients that are
IEEE 802.1x-compliant are moved into the restricted VLAN when the authentication server does not
receive a valid username and password. The switch supports restricted VLANs only in single-host mode.
Beginning in privileged EXEC mode, follow these steps to configure a restricted VLAN. This procedure
is optional.

Purpose
Enter global configuration mode.
Specify the port to be configured, and enter interface configuration mode.
For the supported port types, see the
Configuration Guidelines" section on page
Set the port to access mode,
or
Configure the Layer 2 port as a private-VLAN host port.
Enable 802.1x authentication on the port.
Specify an active VLAN as an 802.1x restricted VLAN. The range is 1 to
4094.
You can configure any active VLAN except an internal VLAN (routed
port), an RSPAN VLAN, a primary private VLAN, or a voice VLAN as
an 802.1x restricted VLAN.
Return to privileged EXEC mode.
