forwarded to the VLAN based on the PVID of its ingress port. All frame 
types are selected by default.
PVID (Port VLAN identifier)—VLAN ID assigned to untagged frames 
received on the interface. The default value is 1. For all other VLANs, an 
interface must first be configured as an untagged member before you can 
assign its PVID to that group.

This section describes how to configure the security settings for the switch.
Configuring 802.1X Settings
Network switches can provide open and easy access to network resources by 
simply attaching a client PC. Although this automatic configuration and access is a 
desirable feature, it also allows unauthorized personnel to easily intrude and 
possibly gain access to sensitive network data.
The IEEE 802.1X (dot1X) standard defines a port-based access control procedure 
that prevents unauthorized access to a network by requiring users to first submit 
credentials for authentication. Access to all switch ports in a network can be 
centrally controlled from a server, which means that authorized users can use the 
same credentials for authentication from any point within the network.
The Cisco SLM2008 switch uses the Extensible Authentication Protocol over 
LANs (EAPOL) to exchange authentication protocol messages with the client, and 
a remote RADIUS authentication server to verify user identity and access rights. 
When a client connects to a switch port, the switch responds with an EAPOL 
identity request. The client provides its identity (such as a user name) in an EAPOL
