Dell N3200-ON EMC Networking N-Series Switches CLI Reference Guide version 6.6 - Page 1077

When configuring an interface for both a data and voice device, set the maxusers limit to 3 if the voice device first authenticates or otherwise uses the data VLAN prior to switching over to the voice VLAN. Command History Syntax updated in version 6.6 firmware. Example The following example configures an interface for a data and voice device. The voice device is a typical IP phone that utilizes the data VLAN to obtain configuration via HTTP prior to authenticating onto the voice VLAN. console(config)#authentication max-users 3 authentication port-control Use the authentication port-control command in Interface Configuration mode to configure the 802.1x mode of authentication on the port. Use the no form of the command to return the mode to the default. Syntax authentication port-control {force-authorized | force-unauthorized | auto} no authentication port-control • auto - Enables 802.1x authentication on the interface and causes the port to transition to the authorized or unauthorized state based on the 802.1x authentication exchange between the switch and the client. Once the first data client is authenticated, any other clients on the interface have access to the data VLAN. This is equivalent to IEEE 802.1X portbased mode. VLAN assignment is allowed on the port if it is not configured in trunk mode. This is the default port-control authentication method. • force-authorized - Disables 802.1x authentication on the interface and causes the port to transition to the authorized state without any authentication exchange required. The port sends and receives normal traffic without 802.1x-based authentication of the client. VLAN assignment is not supported in this mode. Security Commands 1077
