4 802.1X Network Access Control

Guest VLAN

The Guest VLAN feature allows a switch to provide a distinguished service to unauthenticated users. This feature provides a mechanism to allow visitors and contractors to have network access to reach external network with no ability to surf internal LAN.

When a client that does not support 802.1X is connected to an unauthorized port that is 802.1X-enabled, the client does not respond to the 802.1X requests from the switch. Therefore, the port remains in the unauthorized state, and the client is not granted access to the network. If a guest VLAN is configured for that port, then the port is placed in the configured guest VLAN and the port is moved to the authorized state, allowing access to the client.

Client devices that are 802.1X-supplicant-enabled authenticate with the switch when they are plugged into the 802.1X-enabled switch port. The switch verifies the credentials of the client by communicating with an authentication server. If the credentials are verified, the authentication server informs the switch to 'unblock' the switch port and allows the client unrestricted access to the network; i.e., the client is a member of an internal VLAN.

Guest VLAN Supplicant mode is a global configuration for all the ports on the switch. When a port is configured for Guest VLAN in this mode, if a client fails authentication on the port, the client is assigned to the guest VLAN configured on that port. The port is assigned a Guest VLAN ID and is moved to the authorized status. Disabling the supplicant mode does not clear the ports that are already authorized and assigned Guest VLAN IDs.

Configuring the Guest VLAN by Using the CLI

To enable the Guest VLAN Supplicant Mode, use the dot1x guest-vlan supplicant command in Global Config mode.

To configure a VLAN as guest VLAN on a per port basis, enter the Interface Config mode for the port and use the dot1x guest-vlan<vlan-id>command.
