Configuring IEEE 802.1x Authentication Chapter 9 Configuring IEEE 802.1x Port-Based Authentication Step 3 Step 4 Command aaa accounting dot1x default start-stop group radius aaa accounting system default start-stop group radius Step 5 Step 6 Step 7 end show running-config copy running-config startup-config 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. 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. Step 1 Step 2 Command configure terminal interface interface-id Step 3 Step 4 Step 5 switchport mode access or switchport mode private-vlan host dot1x port-control auto dot1x guest-vlan vlan-id Step 6 Step 7 Step 8 end show dot1x interface interface-id copy running-config startup-config Purpose Enter global configuration mode. Specify the port to be configured, and enter interface configuration mode. For the supported port types, see the "IEEE 802.1x Authentication Configuration Guidelines" section on page 9-20. 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. 9-30 Catalyst 2960 Switch Software Configuration Guide OL-8603-04
