Page 191: Vlan Port Configuration
User’s Manual of GS-5220 LCD Series ■ Port Overlapping Port overlapping can be used to allow access to commonly shared network resources among different VLAN groups, such as file servers or printers. Note that if you implement VLANs which do not overlap, but still need to communicate, you can connect them by enabled routing on this switch.
Page 192 User’s Manual of GS-5220 LCD Series • Untagged: Ports with untagging enabled will strip the 802.1Q tag from all packets that flow into those ports.

The initial frame (any kind of frame) sent by a client is snooped by the switch, which in turn uses the client's MAC address as both username and password in the subsequent EAP exchange with the RADIUS server. The 6-byte MAC address is converted to a string on the following form "xx-xx-xx-xx-xx-xx", that is, a dash (-) is used as separator between the lower-cased hexadecimal digits.

Page 364 User’s Manual of GS-5220 LCD Series Figure 4-11-1  Client—the device (workstation) that requests access to the LAN and switch services and responds to requests from the switch. The workstation must be running 802.1X-compliant client software such as that offered in the Microsoft Windows XP operating system. (The client is the supplicant in the IEEE 802.1X specification.) Authentication server—performs the actual authentication of the client.
Page 365 User’s Manual of GS-5220 LCD Series Switch (802.1X device)—controls the physical access to the network based on the authentication status  of the client. The switch acts as an intermediary (proxy) between the client and the authentication server, requesting identity information from the client, verifying that information with the authentication server, and relaying a response to the client.
Page 366 User’s Manual of GS-5220 LCD Series switch port becomes authorized. The specific exchange of EAP frames depends on the authentication method being used. “Figure 4-11-2” shows a message exchange initiated by the client using the One-Time-Password (OTP) authentication method with a RADIUS server.

Page 376 User’s Manual of GS-5220 LCD Series Single 802.1X • In port-based 802.1X authentication, once a supplicant is successfully authenticated on a port, the whole port is opened for network traffic. This allows other clients connected to the port (for instance through a hub) to piggy-back on the successfully authenticated client and get network access even though they really aren't authenticated.

The Link Aggregation Control Protocol allows bundling several physical ports together to form a single logical port. LLDP LLDP is an IEEE 802.1ab standard protocol. The Link Layer Discovery Protocol(LLDP) specified in this standard allows stations attached to an IEEE 802 LAN to advertise, to other stations attached to the same IEEE 802 LAN, the major capabilities provided by the system incorporating that station, the management address or addresses of the entity...
Page 555 User’s Manual of GS-5220 LCD Series table that maps MAC addresses to switch ports for knowing which ports the frames should go to (based upon the DMAC address in the frame). This table contains both static and dynamic entries. The static entries are configured by the network administrator if the administrator wants to do a fixed mapping between the DMAC address and switch ports.
Page 556 User’s Manual of GS-5220 LCD Series from a source VLAN to be shared with subscriber-VLANs. The main reason for using MVR is to save bandwidth by preventing duplicate multicast streams being sent in the core network, instead the stream(s) are received on the MVR-VLAN and forwarded to the VLANs where hosts have requested it/them (Wikipedia).
Page 557 User’s Manual of GS-5220 LCD Series computer systems. NTP uses UDP (datagrams) as transport layer. OAM is an acronym for Operation Administration and Maintenance. It is a protocol described in ITU-T Y.1731 used to implement carrier Ethernet functionality. MEP functionality like CC and RDI is based on this.
Page 558 User’s Manual of GS-5220 LCD Series PHY is an abbreviation for Physical Interface Transceiver and is the device that implement the Ethernet physical layer (IEEE-802.3). PING is a program that sends a series of packets over a network or the Internet to a specific computer in Ping order to generate a response from that computer.

It is used mainly with ADSL services where individual users connect to the ADSL transceiver (modem) over Ethernet and in plain Metro Ethernet networks (Wikipedia). Private VLAN In a private VLAN, communication between ports in that private VLAN is not permitted.
Page 560 User’s Manual of GS-5220 LCD Series individual applications or protocols. A communications network transports a multitude of applications and data, including high-quality video and delay-sensitive data such as real-time voice. Networks must provide secure, predictable, measurable, and sometimes guaranteed services. Achieving the required QoS becomes the secret to a successful end-to-end business solution.
Page 561 User’s Manual of GS-5220 LCD Series In 1998, the IEEE with document 802.1w introduced an evolution of STP: the Rapid Spanning Tree Protocol, which provides for faster spanning tree convergence after a topology change. Standard IEEE 802.1D-2004 now incorporates RSTP and obsoletes STP, while at the same time being backwards-compatible with STP.
Page 562 User’s Manual of GS-5220 LCD Series SNAP The SubNetwork Access Protocol (SNAP) is a mechanism for multiplexing, on networks using IEEE 802.2 LLC, more protocols than can be distinguished by the 8-bit 802.2 Service Access Point (SAP) fields. SNAP supports identifying protocols by Ethernet type field values; it also supports vendor-private protocol identifier.

Page 564 User’s Manual of GS-5220 LCD Series programs at each end have been exchanged. TCP is responsible for ensuring that a message is divided into the packets that IP manages and for reassembling the packets back into the complete message at the other end. Common network applications that use TCP include the World Wide Web (WWW), e-mail, and File Transfer Protocol (FTP).
Page 565 User’s Manual of GS-5220 LCD Series encryption algorithm. TKIP comprises the same encryption engine and RC4 algorithm defined for WEP. The key used for encryption in TKIP is 128 bits and changes the key used for each packet. UDP is an acronym for User Datagram Protocol. It is a communications protocol that uses the Internet Protocol (IP) to exchange the messages between computers.
Page 566 User’s Manual of GS-5220 LCD Series VLAN A method to restrict communication between switch ports. VLANs can be used for the following applications: VLAN unaware switching: This is the default configuration. All ports are VLAN unaware with Port VLAN ID 1 and members of VLAN 1. This means that MAC addresses are learned in VLAN 1, and the switch does not remove or insert VLAN tags.
