Configuring A Guest Vlan - Cisco WS-C2960-24LC-S Software Configuration Manual

Configuring IEEE 802.1x Authentication
Command
Step 3 aaa accounting dot1x default
start-stop group radius
Step 4 aaa accounting system default
start-stop group radius
Step 5 end
Step 6
show running-config
Step 7 copy running-config startup-config
Use the show radius statistics privileged EXEC command to display the number of RADIUS messages
that do not receive the accounting response message.
This example shows how to configure IEEE 802.1x accounting. The first command configures the
RADIUS server, specifying 1813 as the UDP port for accounting:
Switch(config)# radius-server host 172.120.39.46 auth-port 1812 acct-port 1813 key rad123
Switch(config)# aaa accounting dot1x default start-stop group radius
Switch(config)# aaa accounting system default start-stop group radius

Configuring a Guest VLAN

When you configure a guest VLAN, clients that are not IEEE 802.1x-capable are put into the guest
VLAN when the server does not receive a response to its EAP request/identity frame. Clients that are
IEEE 802.1x-capable but that fail authentication are not granted network access. The switch supports
guest VLANs in single-host or multiple-hosts mode.
Beginning in privileged EXEC mode, follow these steps to configure a guest VLAN. This procedure is
optional.

Purpose
Enable IEEE 802.1x accounting using the list of all RADIUS servers.
(Optional) Enables system accounting (using the list of all RADIUS
servers) and generates system accounting reload event messages when the
switch reloads.
Return to privileged EXEc mode.
Verify your entries.
(Optional) Saves your entries in the configuration file.
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 port as a private-VLAN host port.
Enable IEEE 802.1x authentication on the port.
Specify an active VLAN as an IEEE 802.1x guest VLAN. The range is 1
to 4094.
You can configure any active VLAN except an RSPAN VLAN or a voice
VLAN as an IEEE 802.1x guest VLAN.
Return to privileged EXEC mode.
Verify your entries.
(Optional) Save your entries in the configuration file.
