Configuring Port-Based and User-Based Access Control (802.1X) 802.1X Open VLAN Mode 802.1X Open VLAN Mode 802.1X Authentication Commands 802.1X Supplicant Commands 802.1X Open VLAN Mode Commands [no] aaa port-access authenticator < port-list > [auth-vid < vlan-id >] [unauth-vid < vlan-id >] 802.1X-Related Show Commands RADIUS server configuration page 12-19 page 12-52 page 12-46 page 12-54 pages 12-26 Introduction This section describes how to use the 802.1X Open VLAN mode to provide a path for clients that need to acquire 802.1X supplicant software before proceeding with the authentication process. The Open VLAN mode involves options for configuring unauthorized-client and authorized-client VLANs on ports configured as 802.1X authenticators. Configuring the 802.1X Open VLAN mode on a port changes how the port responds when it detects a new client. In earlier releases, a "friendly" client computer not running 802.1X supplicant software could not be authenticated on a port protected by 802.1X access security. As a result, the port would become blocked and the client could not access the network. This prevented the client from: ■ Acquiring IP addressing from a DHCP server ■ Downloading the 802.1X supplicant software necessary for an authenti cation session The 802.1X Open VLAN mode solves this problem by temporarily suspending the port's static VLAN memberships and placing the port in a designated Unauthorized-Client VLAN (sometimes termed a guest VLAN). In this state the client can proceed with initialization services, such as acquiring IP addressing and 802.1X client software, and starting the authentication process. 12-32
