User’s Manual of GS-5220-8P2T2S Managed Switch 4.3.3 VLAN 4.3.3.1 VLAN Overview A Virtual Local Area Network (VLAN) is a network topology configured according to a logical scheme rather than the physical layout. VLAN can be used to combine any collection of LAN segments into an autonomous user group that appears as a single LAN. VLAN also logically segment the network into different broadcast domains so that packets are forwarded only between ports within the VLAN.
User’s Manual of GS-5220-8P2T2S Managed Switch 4.3.3.2 IEEE 802.1Q VLAN In large networks, routers are used to isolate broadcast traffic for each subnet into separate domains. This L2+ Managed PoE+ Switch provides a similar service at Layer 2 by using VLANs to organize any group of network nodes into separate broadcast domains. VLANs confine broadcast traffic to the originating group, and can eliminate broadcast storms in large networks. This also provides a more secure and cleaner network environment.
User’s Manual of GS-5220-8P2T2S Managed Switch ■ 802.1Q VLAN Tags The figure below shows the 802.1Q VLAN tag. There are four additional octets inserted after the source MAC address. Their presence is indicated by a value of 0x8100 in the Ether Type field. When a packet's Ether Type field is equal to 0x8100, the packet carries the IEEE 802.1Q/802.1p tag.
User’s Manual of GS-5220-8P2T2S Managed Switch PVID of the port on which they were received. Forwarding decisions are based upon this PVID, in so far as VLAN are concerned. Tagged packets are forwarded according to the VID contained within the tag. Tagged packets are also assigned a PVID, but the PVID is not used to make packet forwarding decisions, the VID is. Tag-aware switches must keep a table to relate PVID within the switch to VID on the network.
User’s Manual of GS-5220-8P2T2S Managed Switch ■ Untagged VLANs Untagged (or static) VLANs are typically used to reduce broadcast traffic and to increase security. A group of network users assigned to a VLAN form a broadcast domain that is separate from other VLANs configured on the switch. Packets are forwarded only between ports that are designated for the same VLAN. Untagged VLANs can be used to manually isolate user groups or subnets. 4.3.3.

User’s Manual of GS-5220-8P2T2S Managed Switch The Port VLAN is called an "Access VLAN" for ports in Access mode and Native VLAN for ports in Trunk or Hybrid mode. • Port Type Ports in hybrid mode allow for changing the port type, that is, whether a frame's VLAN tag is used to classify the frame on ingress to a particular VLAN, and if so, which TPID it reacts on. Likewise, on egress, the Port Type determines the TPID of the tag, if a tag is required.

User’s Manual of GS-5220-8P2T2S Managed Switch The switch sends BPDUs to communicate and construct the spanning-tree topology. All switches connected to the LAN on which the packet is transmitted will receive the BPDU. BPDUs are not directly forwarded by the switch, but the receiving switch uses the information in the frame to calculate a BPDU, and, if the topology changes, initiates a BPDU transmission.

User’s Manual of GS-5220-8P2T2S Managed Switch HTTPS HTTPS is an acronym for Hypertext Transfer Protocol over Secure Socket Layer. It is used to indicate a secure HTTP connection. HTTPS provide authentication and encrypted communication and is widely used on the World Wide Web for security-sensitive communication such as payment transactions and corporate logons. HTTPS is really just the use of Netscape's Secure Socket Layer (SSL) as a sublayer under its regular HTTP application layering.
User’s Manual of GS-5220-8P2T2S Managed Switch The current version of the Internet Message Access Protocol is IMAP4. It is similar to Post Office Protocol version 3 (POP3), but offers additional and more complex features. For example, the IMAP4 protocol leaves your email messages on the server rather than downloading them to your computer.
User’s Manual of GS-5220-8P2T2S Managed Switch Information Base (MIB), making it possible for the information to be accessed by a Network Management System (NMS) using a management protocol such as the Simple Network Management Protocol (SNMP). LLDP-MED LLDP-MED is an extension of IEEE 802.1ab and is defined by the telecommunication industry association (TIA-1057). LOC LOC is an acronym for Loss Of Connectivity and is detected by a MEP and is indicating lost connectivity in the network.
User’s Manual of GS-5220-8P2T2S Managed Switch using a separate protocol. MVR Multicast VLAN Registration (MVR) is a protocol for Layer 2 (IP)-networks that enables multicast-traffic 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).
User’s Manual of GS-5220-8P2T2S Managed Switch 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. Optional TLVs. An LLDP frame contains multiple TLVs. For some TLVs it is configurable if the switch includes the TLV in the LLDP frame. These TLVs are known as optional TLVs.
User’s Manual of GS-5220-8P2T2S Managed Switch POP3 POP3 is an acronym for Post Office Protocol version 3. It is a protocol for email clients to retrieve email messages from a mail server. POP3 is designed to delete mail on the server as soon as the user has downloaded it. However, some implementations allow users or an administrator to specify that mail be saved for some period of time. POP can be thought of as a "store-and-forward" service.

User’s Manual of GS-5220-8P2T2S Managed Switch 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. UDP is an alternative to the Transmission Control Protocol (TCP) that uses the Internet Protocol (IP). Unlike TCP, UDP does not provide the service of dividing a message into packet datagrams, and UDP doesn't provide reassembling and sequencing of the packets.
User’s Manual of GS-5220-8P2T2S Managed Switch VLAN ID is a 12-bit field specifying the VLAN to which the frame belongs. Voice VLAN Voice VLAN is VLAN configured specially for voice traffic. By adding the ports with voice devices attached to voice VLAN, we can perform QoS-related configuration for voice data, ensuring the transmission priority of voice traffic and voice quality. W WEP WEP is an acronym for Wired Equivalent Privacy. WEP is a deprecated algorithm to secure IEEE 802.11 wireless networks.
User’s Manual of GS-5220-8P2T2S Managed Switch WPS WPS is an acronym for Wi-Fi Protected Setup. It is a standard for easy and secure establishment of a wireless home network.
