FILE LOCATION: C:\Users\gina\Desktop\Checkout_new\Dell Astute\User Guide\Dell_Astute_Features.fm 802.1ab (LLDP-MED) The Link Layer Discovery Protocol (LLDP) enables network managers to troubleshoot, and enhances network management by discovering and maintaining network topologies over multi-vendor environments. LLDP allows a device to identify itself and advertise its capabilities and device information to its neighbors. Identity, capabilities, and device information are sent as Type Length Values (TLVs) in LLDP packets. LLDP devices must support chassis and port ID advertisement, as well as system name, system ID, system description, and system capability advertisements. LLDP Media Endpoint Discovery (LLDP-MED) is an extension of LLDP. It increases flexibility in supporting media applications/devices of different policy and QoS in the same network. With LLDP-MED, media endpoints, such as IP phones and video camera, can advertise information, such as their identity, civic locations, Emergency Location Identifier Number (ELIN), media (voice and video) applications, and network policies to their neighbors. For more information, see Network Administration: Link Layer Discovery Protocol (LLDP). Security Features Dot1x and MAC based Authentication Dot1x and MAC based authentication enables authenticating system users on a per-port or per-device basis. Only users from authenticated ports and devices are granted network access to transmit and receive data. Authentication is enforced via the Remote Authentication Dial-In User Service (RADIUS) server using the Extensible Authentication Protocol (EAP). Dynamic VLAN Assignment (DVA) enables network administrators to automatically assign users to VLANs during the RADIUS server authentication. For more information, see Dot1x Authentications.
